Product Description

Small current monitoring relay
with built-in current trans­former with adjustable set­point and integrated solid
state output. Self-powered
and 2-wire connection for
easy use.

12 mm hole for insulated cur­rent carrying wire makes it
suitable for most applications.
For mounting on DIN-rail.

17.5 mm wide housing suit­able both for back and front
panel mounting.
