Fusebox MT06C161 16A C Curve 6kA MCB Single Pole (Miniature Circuit Breaker (MCB)

This is the Fusebox MT06C161 16A C Curve 6kA Miniature Circuit Breaker (MCB) – DIN Rail Overload & Short-Circuit Protection available at SparksDirect.co.uk for the best price.

The Fusebox MT06C161 is a Single Pole miniature circuit breaker (MCB) engineered to protect electrical circuits from both overloads and short circuits. As part of Fusebox’s MT06C range (C Curve), it’s especially suited to circuits where moderate inrush currents may occur — for example in lighting systems with ballasts or small motor-driven appliances.

MCBs are fundamental safety components in modern electrical distribution systems. Unlike simple fuses that need replacing after a fault, the MT06C161 automatically trips when current exceeds safe limits and can be reset manually once the fault condition is cleared. Its compact design slides onto a 35mm DIN rail in consumer units or distribution panels, making installation neat and straightforward.

Built to comply with EN/IEC 60898-1 safety standards, this circuit breaker provides dependable protection for circuits up to 16A while handling significant fault currents up to 6kA, aligning with UK and EU wiring requirements for residential and light commercial installations.

Features and Benefits

• C Curve tripping characteristic — allows tripping between 5–10× rated current, ideal for circuits with moderate startup surges.
• 16A rated current — suitable for standard socket circuits or power circuits limited to 16A.
• 6kA breaking capacity — protects safely against high fault currents.
• Thermal-magnetic trip mechanism — combines overload and short-circuit protection.
• DIN rail mounted — quick installation on 35mm rails inside consumer units.
• Compact single-module design — saves space in distribution boards.
• IP20 finger-safe rating — basic protection against accidental contact with live parts.
• Standards compliant — meets EN/IEC 60898-1 and applicable wiring regulations.

Three Reasons Customers Recommend This

1. Reliable protection with selectivity — the C curve handles moderate surge currents without nuisance tripping.
2. Compact and easy to install — fast DIN rail fitment saves time during panel builds or upgrades.
3. Compliant with safety standards — gives confidence that circuits are safeguarded per UK/EU wiring requirements.

Who Needs It

• Electricians and electrical installers specifying over-current protection in consumer units and distribution boards where moderate surge tolerance is beneficial.
• Maintenance teams and contractors replacing or upgrading blown breakers in existing installations.
• Homeowners with power circuits that include motors or fluorescent lighting, where C Curve tripping characteristics offer better selectivity than B-curve breakers.

Who Can Install It

• Qualified electricians or competent electrical installers familiar with consumer unit wiring, safe isolation, and wiring standards.
• Not recommended for untrained DIYers — internal panel work should always be done with power isolated and by someone competent due to safety implications.
