This is a three-pole thermal overload relay designed to protect AC circuits from overload, phase failure, long starting times, and permanently blocked motors. It features an adjustment dial for setting adjustable relays, a test button, a stop button, manual/automatic reset, and a trip indication. It includes a cover for sealing and a normally closed/normally open contact as auxiliary contacts. The relay can be mounted directly under three-pole contacts or independently on DIN rails. The insulation voltage is 600 V with a dielectric strength of 6 kV.
