Fusebox MT06B061 6A Single Pole B-Curve 6kA MCB (Miniature Circuit Breaker)

This is the Fusebox MT06B061 6A Single Pole B-Curve 6kA Miniature Circuit Breaker (MCB) – Reliable Overload & Short-Circuit Protection available at SparksDirect.co.uk for the best price.

The Fusebox MT06B061 is a Single Pole thermal-magnetic miniature circuit breaker (MCB) designed to protect electrical circuits from overloads and short circuits. As a Type B curve breaker, it is tailored for residential and light commercial circuits with moderate inrush currents — such as lighting circuits and standard socket circuits — where sensitive and fast-acting protection is needed.

Miniature circuit breakers like the MT06B061 replace traditional ceramic fuses in modern fuseboards and consumer units. When a fault (like an overload or short circuit) occurs, the breaker automatically trips to interrupt the current and prevent damage to wiring and connected devices. After clearing the fault, it can simply be reset — unlike a fuse, which must be replaced.

This particular model is DIN-rail mounted (35mm rail) and designed for easy installation in standard consumer units. With a relatively compact footprint (about one module wide), it helps conserve space in distribution boards while giving robust protective performance.

Compliant with IEC/EN 60898-1 and UK wiring regulations, the Fusebox MT06B061 meets recognised safety and performance standards expected in UK and EU electrical installations.

Features and Benefits

• Thermal-magnetic protection: Combines overload and short-circuit protection in one device.
• Type B tripping curve: Trips between 3–5× rated current — ideal for general-purpose circuits like lighting and sockets.
• Rated at 6A: Suitable for low-Amp circuits where high sensitivity is required.
• 6kA breaking capacity: Can safely interrupt fault currents up to 6 000A at 230V.
• DIN-rail mounting: Easy snap-in installation into standard consumer units.
• IP20 protection rating: Finger-safe enclosure for enhanced safety.
• Compliant with standards: IEC/EN 60898-1 and UK 18th edition wiring regs.
• Compact 1-module width: Saves space in panel design.
