CE Certification 4p Mini Circuit Breaker Exporter – 1P, 2P, 3P, B C D curve, MCB, ETM12, AC, miniature circuit breaker, plug in – Etechin

Feature

ETM12 series MCB is in complied with IEC 60898-1 standard. It has the certification of Semko, CE, CB.
The breaking capacity of ETM12 is 6KA, or 4.5KA
The tripping type is B, C or D curve.
The rated current is (1A, 2A, 3A, 4A) 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A. The rated current is related to different area using for example one pole 10a to 16a ampere is normally used for lighting, 20 ampere to 33 ampere is normally used for kitchen and bathroom area, also used for air conditioner and other line equipment. Some customers will choose 2 pole, 40ampere to 63 ampere as main switch instead of isolator.
Rated insulation voltage: 230V, 240V, 230 / 240V (1 Pole); 400 / 415V (2 poles, 3 poles)
It has single pole (1p), double poles (2p), three poles (3p), and four poles, which is one inch breaker sizes per pole.
There is a position indicator equipped on the products, Red is on, Green is off.
The MCB terminals are IP20 protection which is designed for finger and hand touch safe to keep the safety during installation.
The ETM12 MCB can work reliably in harsh environment, in ambient temperature from -25°C to 55°C.
The electrical life can be up to 8000 operations and mechanical life up to 20000 operations, while the IEC requirement is only 4000 operations and 10000 operations.
The mounting type is plug-in on top terminal ,wiring bottom.

The following are several principles for choosing MCB: 1) The rated voltage of the circuit breaker should not be less than the rated voltage of the line; 2) The rated current of the circuit breaker and the rated current of the overcurrent release are not less than the calculated current of the line; 3) The rated short-circuit breaking capacity of the circuit breaker is not less than the maximum short-circuit current in the line; 4) The selection of power distribution circuit breakers needs to consider the short-time delay short-circuit on-off capability and the coordination between delay protection levels; 5) The rated voltage of the undervoltage release of the circuit breaker is equal to the rated voltage of the line; 6) When used for motor protection, the selection of the circuit breaker should consider the starting current of the motor and make it not operate within the starting time; 7) The selection of circuit breakers should also consider the selective coordination of circuit breakers and circuit breakers, circuit breakers and fuses.
