Industrial 4-Pole Circuit Breaker – 315A, 21kA (MCCB)

This 4-Pole 315A Industrial Circuit Breaker (MCCB) is designed for reliable protection of heavy-duty three-phase electrical systems in industrial, commercial, and infrastructure applications. With a high breaking capacity of 21kA at 400/415V, it safeguards against overloads, short circuits, and electrical faults. The 4-pole configuration offers full-phase and neutral protection, making it ideal for balanced three-phase distribution. Built from durable polycarbonate and compliant with IEC/EN 60947-2 standards, this MCCB delivers long-lasting performance, safety, and reliability in demanding environments.

Applications:

• Industrial facilities: Protects machinery and distribution systems from electrical faults
• Commercial complexes: Ensures safe three-phase power distribution in large buildings
• Manufacturing plants: Prevents costly downtime by shielding critical equipment
• Main and sub-distribution boards: Reliable for both primary and secondary protection
• Construction projects: Provides secure and stable temporary power connections
