Product Description

This 2-pole industrial relay

minimises the space require-

ments in a control cabinet

without compromising perfor-

mance. By applying an input

voltage on control A, the corre-

sponding output semicondcu-

tor is activated at the first zero

crossing of the line

The optimised design is free of

moulding mass to reduce inter-
