Product Overview

The MCB Matching Terminal 4×10mm² is a purpose-built distribution connector engineered to interface directly with standard miniature circuit breakers (MCBs) in modular electrical distribution boards. This compact terminal block enables a single incoming supply to feed up to four 10mm² branch circuits through individual MCBs, delivering a clean, organized, and code-compliant wiring solution for residential consumer units and commercial distribution panels. Its modular design eliminates messy daisy-chaining and reduces installation time significantly.

Wide MCB Compatibility – One Terminal Fits Multiple Brands

This terminal block is designed to work seamlessly with standard 18mm modular MCBs conforming to DIN 43880 and IEC 60898 standards. It supports 1P, 2P (1P+N), 3P, and 4P (3P+N) pole configurations, and is compatible with 63A and 100A frame MCBs. Whether you are working with Schneider (C60/iC60), ABB (S200), Siemens (5SY), Chint (DZ47/NXB), Delixi, or other standard 18mm modular breakers, this terminal provides a universal interface that simplifies panel assembly.

The terminal occupies 4 modules (72mm) on a 35mm top-hat DIN rail (EN 50022), with each outlet position precisely aligned to the standard 18mm module spacing. This ensures that every outlet corresponds directly to the MCB position above or below it on the rail, eliminating alignment guesswork during installation.

Busbar (Comb) Compatibility for Faster Wiring

In addition to direct cable termination, this terminal block is fully compatible with standard finger-safe busbar (comb) connectors. The busbar inserts directly into the terminal's inlet side, distributing power to all four outlets simultaneously and eliminating the need for individual inlet cables. Key busbar compatibility parameters include:

Busbar Pitch

18mm (matching standard MCB spacing)

Busbar Current Rating

63A / 100A (match to MCB rating)

Busbar Type

Pin-type (fork) or clamp-type, insulated (finger-safe)

Using a busbar connector significantly reduces wiring time, minimizes connection points, and improves long-term reliability compared to traditional individual cable daisy-chaining.

Quick DIN Rail Installation in Three Simple Steps

Snap onto DIN Rail

Clip the MCB matching terminal onto the 35mm DIN rail at the desired position-typically at the top or bottom of the MCB row.

Connect Incoming Supply

Terminate the main incoming cable (16–35mm²) to the inlet terminal, or insert a compatible busbar (comb) connector.

Wire Branch Circuits

Connect each of the four 10mm² (or smaller) branch cables from the terminal outlets to the line-side terminals of the corresponding MCBs.

The terminal's IP20 touch-proof design allows safe installation even when adjacent circuits remain live. Always verify all connections are secure and torque values are within specified ranges before energizing the panel.

Typical Applications

This versatile distribution terminal is widely deployed in:

Residential consumer units (CU) and distribution boards (DB)

Commercial sub-panels and modular MCB-based control panels

Lighting distribution boxes

Any installation utilizing standard 18mm modular MCBs requiring a 4×10mm² distribution interface with DIN rail quick mounting
