Miniature Earth Leakage Circuit Breaker Introduction:
It according to IEC 61009-1 standard, protection against the effects of sinusoidal alternating earth fault currents, protection against indirect contacts and additional protection against direct contacts.Assembly on side with LWBX.
Leakage circuit breaker: A switch that can automatically act when the leakage current in the circuit exceeds a predetermined value. Commonly used leakage circuit breakers are divided into voltage type and current type, and current type is divided into electromagnetic type and electronic type.
Leakage circuit breakers are used to prevent personal electric shock, and should be selected according to the different requirements of direct contact and indirect contact with electric shock protection.
miniature Earth Leakage circuit breaker product has a small current of 10mA. It will jump when it leaks. It is safe and worry-free for the family. Choose high-standard protection, overload high-power electrical appliances, short-circuit hazards, leakage hazards, lightning disasters, circuit breaker helps you use electricity safely and eliminate potential electricity hazards. Protect other valuable equipment from damage caused by unstable power supply.
The main differences between ACB-universal (frame type) Miniature Earth Leakage Circuit Breaker, MCCB-molded case circuit breakers, MCB-miniature circuit breakers, and ELCB-leakage circuit breakers are:
(1) The breaking capacity is different. The breaking capacity of ACB is relatively high, followed by MCCB, and MCB is the worst.
(2) The installation position is different. ACB is mostly used as the main circuit breaker (main switch on the power supply side), because it has a delay function, can delay breaking and tripping, and also has good communication functions and selectivity. , And MCCB is mostly used as a power distribution appliance, in the middle of the line, because it only has the breaking capacity and inverse time tripping capability, and does not have selectivity. It can only be used as a lower-level protection switch, an emergency stop switch HW; MCB It is mostly used on the load side because its breaking capacity is relatively low and half is 6000A and 4500A;
(3) The dimensions of the MCB are also very different. The MCB is small in size and easy to install. The ACB has the largest size and is complicated to install. The MCCB is in the middle.
