ASKM3EL Thermal-Magnetic Molded Case Circuit Breaker for General Protection

ASKM3EL Thermal-Magnetic Molded Case Circuit Breaker for General 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 ofACB 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 of Article 4.6 of GB13955-2005.
