Product Description
This 2-pole industrial relay
minimises the space requirements in a control cabinet
without compromising performance. By applying an input
voltage on control A, the corresponding output semicondcutor is activated at the first zero
crossing of the line

The optimised design is free of
moulding mass to reduce internal mechanical stress.
The RA2A..M types have been
specially customised for
