50A relay improves component conductivity

Circuit Protection Electronics relay

TE CONNECTIVITY Potter & Brumfield T92 Series Two-Pole 50A Relay is primarily designed for HVAC, industrial controls, power supply, charging, lighting and inverter applications. The improvement on the key components’ conductivity and heat dissipation capability of this relay provides improved ratings (T92H type, 50A) and enables usage in higher power and temperature environments such as charging applications. Device is the two pole version of the T9 relay family – offered with either a form A or form C contact arrangement. The normally open contacts are nominally rated 30A, and there is a 40 A UL rating. The normally closed contacts on the form C version are not intended for power switching and are rated 3 A. Devices are available with a dc coil requiring 1.7W or an ac coil requiring 4VA of power.
