These Power Relays come with auxiliary contact block included. Additional auxiliary contact blocks can be bought separately.

Capable of switching 40A at 440Vac (4-pole power fully applied 160A)
Compact, 40% smaller than contactors (IEC-AC1, 50A specifications)
Mirror contacts for safety function
Low noise, approx. 70dB
Low Power consumption, less than 4W dc
High insulation, load switching for 400Vac systems
Bifurcated crossbar contact
Simple mounting

For mirror contact mechanisms (certification to EN60947-4-1) refer to manufacturer datasheet for precautions for correct use. Compliance attained through a combination of the relay and auxiliary blocks.
