American ZETTLER continues to be a highly competitive source for relays supporting a wide spectrum of applications such as HVAC, Industrial, Motor Control, Power Controls and Food Services. As a market leader in the PCB relay component industry, we also offer highly convenient replacement “drop-ins” for competitive relays that have recently been or are in the process of being discontinued.
A few years ago, Omron discontinued their G8P and G5LA series relays, and recently TE Connectivity discontinued their T9 relay. Now Panasonic has announced “end-of-life” for their JS1, JTN and JTV relay series – all without replacements.
Our AZ943, AZ2100, AZ2150 & AZ2280 series are suitable replacement “drop-ins” and we are here to stay with these series. Please see below for the discontinued competitors’ series and the ZETTLER series crosses (with hyperlinks).
Due to the growing market for electric vehicles, the demand for charging infrastructure products is increasing rapidly. During the initial phases of the e-mobility rollout, mostly purely functional Mode 2 charging cables in accordance with IEC62752 were required. Today, manufacturers are also paying more and more attention to an attractive design with a high recognition value. There is also a strong focus on reducing the size of such devices.
A market leader in the field of high-end charging infrastructure approached ZETTLER because they desired a relay according to IEC62752 for its new generation of mode 2 charging cables with additional customized design features. Based on the experience and variety of reliable ZETTLER relays, a customized version was built according to the customer’s needs. The customer is highly satisfied with the resulting individualized relay solution, packaged in a tailor-made housing and printed in its own design.
ZETTLERs AZEV132 relay is a 1-pole power PCB relays, initially developed specifically for use in accordance with IEC62752 and, more importantly, to meet the exceedingly stringent short-circuit withstand-current requirements of this standard. These relays also have a monitoring contact to allow detection of any possible welding issues with the main contacts. The relays are approved at UL, CUR and TÜV with ratings of up to 40 A with 6k switching cycles (32 A with 50k switching cycles) for the normally open load contact and 10 mA at 12 VDC with 50k switching cycles for the normally closed monitoring contact.
A new version with switching capability of up to 50A, our AZEV140, is planned for series production in 2021.

Previously in Part 1 of this series, we explored electromagnetic components from ZETTLER Magnetics used in the conversion of 480VAC to lower AC (or DC) voltages. In Part 2, we explore electromechanical components from American ZETTLER that are capable of switching or isolating high voltage circuits operating at 480VAC. This ranges from bulky definite purpose contactors which handle the higher power loads more commonly associated with 480VAC circuits down to miniature power (latching) relays popular in lighting.
These robust switches offer safety approvals and certified ratings well suited for a number of applications including refrigeration, air conditioning, heating, elevators, food service equipment, cranes, hoists, welding machines, power supplies, vending machines, lighting, pumps and compressors.
XMC0 Definite Purpose Contactors are available in various pole configurations with options for auxiliary contacts, micro switches, and mechanical interlocks

The demand for switching higher currents and higher voltages on increasingly smaller footprint continues to grow, especially in Solar and EV charging applications. ZETTLER is following this trend by introducing its newest type of “New Energy” relays, the 50A AZSR143.
The AZSR143 has a maximum UL/TUV switch rating of 50A@277VAC with 6K cycles. Other ratings include 43A@277VAC (85°C) and 33A@277VAC (105 C) with 30K cycles each and 50A@277VAC carry current with 50K cycles (on/off) at 20A. It features a 1.8mm contact gap, a 4500Vrms dielectric strength and a minimum holding power of 196mW.
Mainly designed for solar inverters, the AZSR143 is also well suited for for electric vehicle charging equipment.
Innovation in product design is how ZETTLER is leading the field of new energy application solutions. Please also Contact Us for other relay products in that category, such as the 16/32A AZEV116/AZEV132 , the 65/90A AZSR165/AZSR190 or our 35A AZSR131 as well as our flagship solar relay, the 50A AZSR250.

Global plug-in electric vehicles sales for the first half of 2019 reached more than 1.1 million units- a 46% increase over prior year. Estimated global sales for 2020 are projected to reach 4 million units, reaching 12 million units in 2025, and 21 million in 2030.
This positive trend is also evident in associated sales of charging infrastructure solutions. In particular, wall charging stations – so-called “wallboxes” – that enable EV charging with AC voltage according to charging mode 3 (IEC 61851-1) are and will continue to be in extraordinary demand. They facilitate charging of electric vehicles with voltages up to 400V, and are used in protected areas such as parking garages, carports or private homes.
A supplier of wallboxes contacted ZETTLER in Europe, because of their need for a relay compliant with the requirements of IEC 61851-1 for a new generation of EV charging wallboxes. The relays of ZETTLER’s AZSR131 series have a normally open contact (1 form A) and are UL and TÜV approved with 35A 277VAC and 30,000 switching cycles or 33A 277VAC and 50,000 switching cycles with TÜV. The relays are available in the standard version with 1.8mm contact gap and in a special version with up to 2.3mm. The relays are also available in a version in accordance with the extended household appliance standard IEC 60335-1 (GWT). This component solution in the EV charging space along with others, such as the new AZEV132 EV charging relay, keeps ZETTLER relays at the forefront in this significant green energy growth segment.
Please Contact Us for samples and data sheets of these new ZETTLER EV charging relays or similar solutions or to discuss the wide variety of application opportunities for the range of ZETTLER Relays.
Electromobility is progressing steadily and the plans of many car manufacturers to ultimately exit internal combustion engine technology are becoming ever more concrete.
As with almost all emerging technologies, application-specific standards for EV charging have continuously evolved over the years as safety concerns and impacts to the electric utility grid were considered. For early pioneers of electrical vehicle supply equipment (EVSE) or charging stations, this meant constant re-engineering of existing systems to meet regional standards and uncertainty around future certification requirements.
For the charging of electric vehicles using household or CEE sockets, the IEC62752 standard offers system designers a welcome sense of clarity on what future regulations are likely to require. Charge mode 2 (Level 2 charging / IC-CPD) addresses necessary control and safety requirements for charging cables along with considerations for the type of currents and service life these products will endure.
Fortunately for hardware designers of EVSE systems, ZETTLER’s new relay series AZEV116 and AZEV132 were developed specifically for use in accordance with IEC62752 and, more importantly, to meet the exceedingly stringent short-circuit withstand-current requirements of this standard. These relays also have an isolated signal monitoring contact to allow detection of any possible welding issues with the main contacts.
Designed for charging systems of charge mode 2 (IEC62752).
Normally open (1 Form A) with wide contact gap ≥ 2.25 mm.
