Product Features of the Type C MCB

Engineered from halogen-free, RoHS-compliant thermoplastics, this type c mcb integrates modular expansion capabilities to enhance long-term operational safety.

Reliable Short-Circuit Defense: Achieves a rated short-circuit capacity (Icn) of 4.5kA to decisively interrupt and clear severe fault currents.
Finger-Safe Terminals: Features IP20-rated incoming and outgoing terminals, preventing accidental operator contact during active maintenance.
Versatile Connectivity: Supports both standard flexible/rigid cables (up to 25mm²) and pin-type busbars for accelerated panel wiring.
Visual Status Recognition: Incorporates a mechanical red/green contact position indicating device for immediate switching status verification.
Eco-Friendly Construction: Utilizes state-of-the-art thermoplastics to allow complete MCB recycling, actively reducing environmental pollution.
