Product Features of the RCCB Type B

Built for heavy-duty commercial deployment, this RCCB Type B utilizes an advanced electro-magnetic tripping mechanism to guarantee instantaneous, fail-safe fault clearance.

Comprehensive Leakage Detection: Detects smooth DC and composite waveform leakage at any level up to 1kHz, completely eliminating the risk of RCD “blinding”.
Heavy-Duty Isolation Capacity: Achieves a formidable 10kA rated conditional residual short-circuit current (IΔc), clearing severe faults instantly (≤0.1s).
Touch-Safe Design: Features IP20 finger-protected incoming and outgoing terminals to secure live parts from hazardous operator contact during maintenance.
Immediate Status Verification: Integrates a prominent red/green mechanical indicating device on the faceplate for instant switching status recognition.
Flexible Wiring Architecture: Accepts standard flexible cables (up to 16mm²), rigid cables (up to 25mm²), pin-type busbars, and fork-type busbars via bidirectional routing.
