Product Overview
The RCCB Matching Terminal 100 Type is a specialized high-current connection block designed to perfectly complement 100A frame residual current circuit breakers (RCCBs) used in main distribution boxes, industrial control panels, and EV charging stations. Engineered to match the standard spacing of 100-type RCCBs (2P or 4P), this terminal block provides clean, organized, and reliable wiring for both incoming and outgoing RCCB connections. It supports conductors up to 35mm² and full 100A current rating, aligning exactly with RCCB specifications. The block mounts directly alongside RCCBs on the same 35mm DIN rail, allowing a professional installation that saves approximately 35% of panel space. Ideal for high-current main distribution applications, it enhances wiring efficiency and space utilization for panel builders, electrical contractors, and main distribution box manufacturers managing 100A circuits.
