Fusebox MT06C061 6A Single Pole C Curve 6kA MCB (Miniature Circuit Breaker)

This is the Fusebox MT06C061 6A Single Pole C Curve 6kA Miniature Circuit Breaker (MCB) – Enhanced Overload & Short-Circuit Protection available at SparksDirect.co.uk for the best price.

The Fusebox MT06C061 is a Single Pole miniature circuit breaker (MCB) designed to protect electrical circuits from overloads and short circuits in distribution boards and consumer units. It is part of the Fusebox MT06 series, which includes both B-curve and C Curve MCBs; the C Curve version is tailored for circuits that may experience moderate inrush currents — such as lighting with fluorescent ballasts, small motors, or heavy loads — where a slightly delayed trip is beneficial.

When a fault condition occurs (like too much current drawing through the circuit), the MT06C061 automatically disconnects the circuit using a thermal-magnetic trip mechanism, helping to prevent cable overheating, equipment damage, or fire hazards. After the fault is cleared, the breaker can be reset by switching it back on, which is more convenient and safer than replacing a fuse.

This MCB is DIN-rail mountable, making installation quick and compatible with most standard consumer units and panel boards, and it’s built to comply with recognised safety standards including BS EN 60898-1.

Features and Benefits

• C Curve trip characteristic – trips between about 5–10× rated current, suitable for loads with moderate start-up surges.
• 6kA breaking capacity – safely interrupts fault current up to 6000A at 230V.
• Thermal-magnetic trip mechanism – protects against both sustained overloads and sudden short circuits.
• Single Pole design – protective device for live conductors in single-phase systems.
• DIN-rail mounting – easy snap-in installation on standard 35mm rails.
• Compact space-saving module – conserves space in distribution boards.
• Compliant with UK/EU safety standards – meets BS EN 60898-1, suitable for consumer and commercial installations.

Three Reasons Customers Recommend This

1. Enhanced surge handling — C Curve trip makes it better suited than B-curve for circuits with moderate inrush currents (e.g., motors & ballasts).
2. Reliable protection — automatic trip and reset capabilities offer dependable defense against overloads and faults.
3. Compact and cost-effective — delivers good performance while saving space and budget in distribution panels.

Who Needs It

• Electricians and electrical installers specifying circuit protection where moderate inrush loads are expected.
• Maintenance teams upgrading or replacing breakers in consumer units.
• Commercial or light industrial installations where C Curve protection provides better selectivity for certain loads.

Who Can Install It

• Qualified electricians or competent electrical installers familiar with consumer unit configuration and safety standards.
• Not recommended for DIY novices: internal panel work should be done with power isolated and by someone competent due to electrical hazards.
