Scope of application

3TM1E series intelligent molded case circuit breaker, it is the factory USES the international first when the design, manufacture technology development, the development of one of the new type of circuit breaker. Its rated insulation voltage is 800 v, applied to ac 50 hz, rated voltage 400 v, rated current 800 a do not frequent conversion circuit and motor is not frequent starting. Circuit breaker with overload long time delay inverse time, short circuit, short time delay inverse time, short circuit the short time delay time instantaneous and owe voltage, short circuit protection function, can protect circuit and power equipment from being damaged.

Circuit breaker can be installed vertically (that is, vertical pack), can be installed horizontally (that is, the horizontal loading).

This circuit breaker shall not fall in line, the only allowed to connect power 1, 3, 5, 2, 4, 6, the load line.

The circuit breaker to perform the following criteria:

IEC60947-1 and GB/T14048.1 conditions;

IEC60947-2 and GB/T14048.2 low E circuit breaker and appendix F electrons overcurrent protection circuit breaker of the additional requirements;

IEC60947-4 GB/T14048.4 contactor and motor starter;

IEC60947-5.1 and GB/T14048.5 electromechanical control electric circuit.

The main performance characteristics

3TM1E series intelligent molded case circuit breaker with three protection function, use category for B breaker and connected to the other in the same circuit short circuit protection device with selective completely under the condition of short circuit;

Five kinds of tripping characteristics; The user can according to the load current requirements set to adjust for trip;

Electronic tripping device provided by the circuit breaker itself energy, current signal and the control power supply from the installation of the ring current transformer in the circuit breaker;

With early additional instructions: when the load current exceed the set current, the light emitting diode on the circuit breaker cover indicates to yellow;

With overload indicator: when the negative when the current exceeds the setting current, circuit breaker cover on the led Cha instructions in red;

Has the fire special overload trip not only to glance function: when the load current overload operation, circuit breaker tripping, passive contact output a signal, drive the corresponding alarm device;

In line with the IEC60947 appendix F electromagnetic compatibility requirements.
