TEM1 Moulded Case Circuit Breaker
TEM1 Moulded Case Circuit Breaker

Application
TEM1 Series of moulded case circuit breaker is one of our new type products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 660V and used for circuit of A.C.50Hz, rated
operating voltage AC 380V. (Or below), rated operating current up to 800A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current, short circuit and under voltage, the products are capable
of preventing damage of circuits and supply units.
Classication
Accord to product poles. Two kings of three-pole are provided The neutral pole(N pole) of four poles has four types

Performance Curve of Release



Protection Characteristics
The thermodynamic release of a circuit breaker provides the feature of inverse time delay, while the magnetic release is the instantaneous operation as show on table 2 (distribution circuit-breaker) and table 3 (motor protection circuit breakers).
