Electronic Components for 480VAC Applications (Part 2/2)

Application Spotlight, July 2020.

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.

Perspective:  A smaller XMC0 contactor next to AZSR1200, AZSR190, AZ2800, and AZ576 power relays.
Featured Products   Load Ratings
XMC0 Definite Purpose Contactors are available in various pole configurations with options for auxiliary contacts, micro switches, and mechanical interlocks 25-90 FLA up to 600VAC
125-450 LRA at 480VAC
AZSR1200, AZSR1180, and AZSR1160 single pole PCB mount power relays are well suited for solar inverter applications Make/break 40A, carry up to 200A, 920VAC (85 C)
50 make/break cycles up to 200A, 920VAC (85 C)
AZSR190 and AZSR165 single pole PCB relays are common in both solar and EVSE applications Up to 55A at 480VAC (85 C) for 30k cycles
Up to 100A at 480VAC (85 C) for 1k cycles
AZ2800 (panel mount) and AZ2850 (PCB mount) are popular double-pole power relays available in DPST and DPDT configurations 8 FLA or 10A general use on normally open contacts up to 600VAC
2 FLA or 2A general use on both normally open and closed contacts at 480VAC
AZ576 (non-latching) and AZ576P (latching) miniature power relays in single pole configurations are great for lighting and other smaller loads on 277, 347 or 480VAC circuits 3.7A std. ballast at 480VAC (105 C)
2.7A elec. ballast at 480VAC (105 C)
1HP rating at 480VAC (85 C)
