Polarized latching relay TP41-28A, with continuous switching current capability up to 120A. The relay coil can be designed to single winding and double winding with coil voltage from 5VDC to 48VDC. The advantage of polarized latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. The relay is designed and manufactured in accordance to IEC 61810-1 as well as meet the requirements of IEC 62055-31.
1. Single phase 120A switching capability;
