Product Features

Reliable Overload & Short-Circuit Protection:The WCP Push-in MCB safeguards electrical systems with thermo-magnetic release technology (B/C/D curves), offering precision protection against overloads and short circuits. Its 6kA breaking capacity ensures rapid fault interruption, minimizing equipment damage and downtime in lighting, motor control, and power distribution networks.
Space-Saving Push-in Design:Engineered with a compact modular structure and IP20-rated enclosure, this MCB optimizes panel space while resisting dust ingress. Its lightweight yet durable build supports seamless integration into modern electrical setups, even in confined spaces. The push-in terminal design simplifies installation, reducing labor time and costs.
High-Performance Durability:Built to endure demanding conditions, the WCP MCB operates reliably across ambient temperatures -5°C to +40℃ (storage: -25°C to +70℃) and withstands 8,000 electrical operations. Fire-resistant materials and 4kV impulse voltage resistance ensure longevity in residential, commercial, and industrial environments.
Compliance & Versatility:Compatible with 230/400V, 50/60Hz systems and certified for 2kV dielectric strength, this MCB meets rigorous safety standards. Its multi-pole configurations (1P, 2P, 3P, 4P) and 6–40A adjustable current range adapt to diverse applications, from machinery control to grid infrastructure.
Certified Safety Assurance:Designed with 30°C thermal calibration and tested for stability under extreme conditions, the WCP MCB aligns with global electrical safety benchmarks, ensuring trusted performance in critical installations.
