proof relay

Description

The LSR-0 is a self-powered load sensor intended for use as a

proof relay. It is used to verify that current is ﬂowing as intended.

It has a guaranteed 15A pull-in current and 2.5A drop-out current.

Proof relays are typically used to interlock fans, compressors,

motors, heating elements and other devices. The LSR-0 is

self-powered, that is, it draws its power from the wire being

monitored so it does not require separate control power wiring.
