Product Description:

Rated residual operating current I△n: 100mA/300mA/500mA/1000mA (adjustable/non-adjustable)

Operating time: ≤0.2s (non-delay type); 0.5s/1.15s/2.15s (delay type)

N-pole type of 4-pole MCCB:

    A: N-pole is always close without overload release

    B: N-pole is open or close together with other three poles and without overload release

    C: N-pole is open or close together with other three poles and with overload release



· Small size, high breaking capacity, short arc, shake-resisting, and so on.

· Suitable for both vertical and horizontal installation.

· With isolating function.

· Residual current of the protecting modular is from 3 phases, making it possible to work normally in case of default of any phase.

· Adjustable on the site: With three grades of residual current and three grades of delay time. User can adjust them according to the requirements on the site.

· Indication of working status: Normal-Green lamp; Fault-Red lamp; Alarm-Yellow lamp (≥25%I△n).

· Good performance under voltage faults: Be able to perform residual current protection when phase voltage drops to 50V.

Q:Is the zero line going through the circuit breaker?
Three-phase three-wire, the use of protection to zero system, the zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken,
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
Used to control, protect, adjust, measure and monitor the parameters of the circuit and the working conditions of each component.
Q:What is the solution of the leakage circuit breaker always jumping?
if it exceeds its rated current or leakage, primarily for home or office lighting and to ensure the safety of the person.
Q:How to choose the home of the circuit breaker air switch?
air conditioning circuit, separate wiring, when one of the circuit (such as the socket circuit) failure, the other circuit can still be normal power supply.
Q:What is the choice of low voltage electrical circuit breaker?
At present, some high-performance circuit protection devices provide circuit breakers specifically designed for extreme shock and vibration environments.
Q:How is the total switch breaker in the distribution box correctly
protection current in the grid after the protection, then the command will be the leakage protector trip occurs when the control of the main circuit breaker trip
Q:Does the isolator and circuit breaker able to switch to each other?
As the circuit breaker inside the arc suppression mechanism, the circuit breaker in a very short period of time (such as a few hundred seconds) will arc off, so that the circuit breaker safety separation.
Q:Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
the current flows through the LED When the GPRS high, the emission junction reverse bias, collector junction reverse bias, work in the cut-off area
Q:Household leakage circuit breakers, circuit problems
Leakage circuit breaker DZ47LEC63, electric problem. Anxious ~ ~ ~ ~ ~ reward points: 80 - from the end of the problem there are 14 days 23 hours 1
Q:What is the difference between a circuit breaker and other switches?
In practical applications, more than 800A loop or segmentation capability requires particularly high circuit or the need for more features of the circuit should be used frame circuit breaker,
