The Potric WSB1-125H 3 Pole Miniature Circuit Breaker (MCB) is engineered to provide high-performance circuit protection for low-voltage three-phase electrical systems. With a breaking capacity of 10kA, it effectively interrupts fault currents caused by overloads and short circuits, helping to protect electrical installations, equipment, and personnel. Designed according to IEC / EN 60898-1 standards, the WSB1-125H series is suitable for demanding commercial and industrial applications where higher fault current protection is required. Its compact DIN rail mounting design allows easy installation in distribution boards, switchboards, and control panels. Available in a wide range of current ratings and tripping curves, the WSB1-125H series offers flexibility for various electrical protection requirements. Built with durable materials and a reliable operating mechanism, this MCB ensures long service life, stable performance, and enhanced safety in modern electrical systems.
