RFW5–Limit value switch for terminal W of a 24 V three-phase generator : NORIS Group GmbH

Limit value switch for 24 V three-phase generator input
Simple application; for harsh environments
Limit value adjustable by drum scale
Normally open or normally closed version
Compact and robust construction
Operating status indication by integrated LED

Limit value switches of type RFW5 monitor electrical measured variables. The integrated relay switches when the actual value present reaches the set target value. Normally open devices can also be equipped with a self-latching feature as an option. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
