ARM5 double breaking type high Icu=Ics MCCB Main functions and features
Pneumatic Protection Device: When the circuit breaks with large current, the gas in the contact unit box is rapidly pressurized, and the pneumatic protection device rapidly fluctuates the operating mechanism latch under strong air pressure, greatly reducing the damage of the breaking current to other electrical components and buses.
Magnetic Blow Design: The current flows through the fixed contact to generate an electromagnetic source, which forms an annular magnetic field arc with the iron core and quickly enters the arc extinguishing chamber under the action of the magnetic field, which is conducive to quickly break the current.

Frequently Asked Questions
What are the main functions of the ARM5 double breaking type MCCB?
The ARM5 series molded case circuit breaker features a double breaking type structure, providing high ultimate short-circuit breaking capacity (Icu=Ics). It includes a pneumatic protection device to prevent current damages and a magnetic blow design for rapid current interruption.
How does the pneumatic protection device protect electrical components?
During a high current interruption, gas in the contact unit box is quickly pressurized. This air pressure rapidly trips the mechanism latch, reducing damage to other components and buses.
What is the advantage of the magnetic blow design in ARM5 MCCBs?
The magnetic blow design uses the electromagnetic field generated by current flowing through fixed contacts to create an annular magnetic field. This field pushes the arc into the extinguishing chamber, ensuring fast and safe current interruption.
What are the mechanical and electrical lifespans of the ARM5-400 model?
The ARM5-400 MCCB offers high durability with a rated mechanical life of up to 7,000 operations and a rated electrical life of 1,000 operations under 400In conditions.
What insulation and impulse withstand voltages can the ARM5 series handle?
The series features a high rated insulation voltage (Ui) of 1000V and can withstand a rated impulse voltage (Uimp) of up to 12kV, making it ideal for demanding industrial environments.
