300A Series 31 Industrial Power Relays

TE Connectivity's (TE) / KISSLING 300A Series 31 Industrial Power Relays are bistable relays designed to operate in harsh environments. The series features electronic functions for pulse-coil protection, a low-energy switching input for direct connection to an electronic control unit (ECU), and an optional "energy" function for fail-safe shutoff when power is lost. TE KISSLING Series 31 power relays are offered in 300A variants and in three control types: ENERGY, INIT, and SAFETY. These robust relays are designed for battery management and power distribution applications.
