Description

Gray Bakelite Shell Thermal Overload Relay STH-40 Auxiliary Contact Block

STH series of thermal overload relay can be used in the circuit of 50/60 HZ, rated insulation voltage 660 V, rated current 0.1-93A for protecting the phase break when the electric motor is overload , the relay has different mechanism and temperature compensation can be pluged in ST1 series AC contactor,It is the most advanced thermal relay in the nineties in the world the products comply with IEC 60947-4.

The thermal relay works on the principle of the thermal effect of electrical energy. The bimetallic strips, heating coils and the current transformers are the important parts of the thermal relay.
