ASKM3EL Thermal-Magnetic MCCB with Integrated Residual Current Protection

ASKM3EL LCD Electronics Molded Case Circuit Breaker with Residual Current Protection

Basing on the ASK3EL MCCB, we integrate the residual current protection function, we produce a new LCD intelligent electronic leakage protectiontype circuit breaker ASKM3EL (MCCB for short). MCCB can display real-time three phases currents, voltages and residual currents and upload datathrough communication network, realizing four remote functions and meeting the requirements of Low-voltage molded case circuit breakercommunication protocol

MCCB have protections for overload, short- circuit, under-voltage, over-voltage, phase-loss, zero-loss, can protect circuits and equipment fromdamage. MCCB also have residual current protection, providing protection against dangerous voltage exposure to people due to insulation damage.The selective protections of ACB have high accuracy, which can improve the reliability of power supply and avoid unnecessary power outages.

MCCB is suitable for the distribution network of AC 50Hz, rated insulation voltage 1000V, rated voltage 400V and rated current up to 800A. MCCB can beused for infrequent switching of lines and infrequent starting of motors. Special places can use leakage alarm non-tripping module to avoid majorlosses caused by power outages. MCCB meet the requirements ofArticle4.6 of GB13955- 2005.

FAQ

1、What accessories can be installed?

Alarm contact, shunt release, auxiliary contact, undervoltage release, electric operating mechanism, manual operating mechanism, machine operating mechanism

2、What are the reasons for frequent tripping?

Possible causes include: excessive load, circuit short, unstable voltage, internal fault or improper trip setting.

3、Can this type of MCCB be used in DC circuits?

Currently only available for AC400/415V, AC660/690V.

4、What should I do if the MCCB can't close the brake?

Check whether overload or short circuit is not ruled out.

Check whether the operating mechanism is stuck.

Check whether the undervoltage trip and shunt trip are operational.

Check that the auxiliary contacts and interlocking mechanisms are correct.
