ARM5 double breaking type high icu=ics mccb Main functions and features
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.
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.

Technical FAQ details regarding the ARM5 MCCB
The ARM5 double breaking type MCCB features high Icu=Ics breaking capacities, utilizing a pneumatic protection device and a magnetic blow design to ensure reliable circuit interruption and component protection.
When a large current breaks, the gas in the contact unit box is rapidly pressurized. This strong air pressure causes the pneumatic protection device to quickly fluctuate the operating mechanism latch, minimizing damage to buses and other electrical components.
The magnetic blow design generates an electromagnetic source as current flows through the fixed contact. This forms an annular magnetic field arc with the iron core, guiding the arc rapidly into the extinguishing chamber for quick current interruption.
Yes, the ARM5 is designed as a double breaking type circuit breaker offering high Icu=Ics performance, suitable for demanding electrical systems.
By combining rapid pneumatic latch fluctuation and quick magnetic arc extinguishing, the MCCB significantly reduces the duration and impact of fault currents, thereby safeguarding buses and connected electrical devices.
