The ARM1L-250A 4P Residual Current Circuit Breaker is a premium-grade molded case circuit breaker designed for industrial and commercial electrical distribution systems. This 250A rated MCCB features advanced protection capabilities including residual current detection, overcurrent protection, and short-circuit protection.
With its 4-pole configuration, this circuit breaker is ideal for three-phase systems requiring neutral protection. The unit operates at AC 50Hz with a rated voltage of 400V, making it suitable for most industrial power distribution applications. The breaker incorporates both thermal and magnetic trip mechanisms for reliable overload and short-circuit protection.
The innovative design ensures stable performance even under phase loss conditions, with adjustable residual current settings and tripping time parameters. The compact dimensions (142×165×110mm) allow for space-efficient panel mounting while maintaining excellent heat dissipation characteristics.
Key technical features include a high breaking capacity (50kA Icu), mechanical endurance of 7000 operations, and compliance with international safety standards. The unit's robust construction includes arc chutes for effective arc extinguishing and silver alloy contacts for enhanced conductivity and durability.
This circuit breaker is particularly suitable for applications requiring personnel protection against electric shock and prevention of fire hazards caused by insulation faults. It provides comprehensive protection for electrical circuits against overloads, short circuits, and earth leakage currents.
