LR-power relay
the power relay LR
LR relays are power relays which convince by her brilliant simplicity. The
mature and simple construction will predestine this relay for the rough and
uncompromising use.
By using best materials and because of
the simple construction a max. mechanical and electrical life time was achieved.
The special advantages of this mature
relay lie in the high switching power as
well as in the low power consumption
of the coil.
The LR relay is available in AC- and also
in DC- version
