Dold Monitoring Relay, 3, 1 Phase, 0 to 500 V Monitor Range, DPDT, DIN Rail 110 to 240 V dc

The Dold Monitoring Relay is a reliable three-phase, single-phase voltage monitoring device designed to protect electrical systems by continuously monitoring voltage conditions. It supports a 0–500 V monitoring range and provides DPDT (Double Pole Double Throw) relay contacts for dependable switching and control.

Designed for convenient installation, the relay operates from a 110–240 V DC supply and is suitable for DIN-rail mounting inside control panels and electrical enclosures. It can help detect abnormal voltage conditions and provide a control signal for protective or shutdown circuits.
