TNID earth leakage circuit breaker is suitable to the circuit of AC 50/60Hz. rated voltage 230V for 2 poles and 400V for 4
poles, and rated current up to 100A. when people come across the electric shock or the leakage current of the electrical network exceeds the fixed value, this product can cut off the fault current in short period so as to protect person and the equipments, It also can be used in the infrequent starting of the circuit and motors.
The circuit breaker is suitable to industry, commerce, high-rise building, household and other kinds of places.
■In complicance with IEC/EN61008.1.
■Bilateral busbar wiring capabilities to adapt to the wider use of premises.
■Maximum connecting ability of 35mm, wiring torque 3.5N*m, applicable to a variety of installing equipment.
■Protection class: IP20.
