1630

5

Description

The power relay HPR10 belongs to E-T-A’s product group of high-

current relays. The hybrid version also features the electro-mechanical

relay system plus an active electronic control unit for signal conditioning.

This creates a wide range of options regarding activation and func-

tionality of the power relay.
