160 A Thermal Overload Relay

A bimetallic thermal overload relay for three-phase asynchronous motors, offered in three frame sizes with settings up to 20 A, 63 A and 160 A. It uses temperature-compensated bimetallic sensing with switchable manual or automatic reset and 1NO + 1NC auxiliary contacts, housed in flame-retardant bakelite with large screw terminals and a fixed base that mates with common AC contactors. Typical duties are pump, fan, compressor, machine tool and HVAC motor circuits inside closed cabinets. Match the frame size and setting range to the motor full-load current and allow for IP20 indoor mounting.Key details:Materials: High flame-retardant bakelite plastic housing
