Product details

Product Overview: 

 TM1E series intelligent molded case circuit breaker is one of the new circuit breakers developed and researched by our factory using internationally leading design and manufacturing technology. Its rated insulation voltage is 800V, suitable for infrequent conversion and motor starting in circuits with AC 50Hz, rated working voltage of 400V, and rated working current up to 1250A. The circuit breaker has overload long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay timed limit, short circuit instantaneous and undervoltage protection functions, which can protect the circuit and power equipment from damage. Execution standard: GB/T14048.1; GB/T140482。

Circuit breakers can be installed vertically or horizontally

Model meaning:

Main performance characteristics:

  TM1E series intelligent molded case circuit breaker has three-stage protection function, suitable for Class B circuit breakers and other short-circuit protection devices connected in the same circuit, with complete selective coordination under short-circuit conditions;

There are five types of trip characteristics to choose from: Users can adjust the settings of the trip according to the load current requirements:

The electronic release is powered by the circuit breaker itself, and the current signal and control power come from the annular current transformer installed inside the circuit breaker:

Equipped with warning indication: When the load current exceeds the preset current, the LED on the circuit breaker cover indicates yellow;

Overload indication: When the load current exceeds the set current, the LED on the circuit breaker cover indicates in red;

Equipped with a fire specific overload non trip alarm function: when the load current is overloaded, the circuit breaker does not trip and outputs a power contact signal to drive the corresponding alarm device: in accordance with the electromagnetic compatibility requirements of Appendix F of IEC60947;

When the intelligent molded case circuit breaker has isolation function, its corresponding symbol is:

The external dimensions are the same as those of the TM1 series molded case circuit breaker, and the installation is interchangeable.
