Single-pole MCBs provide overcurrent and short-circuit protection for individual live conductors on single-phase circuits. They are the standard protective device used in most UK consumer units and distribution boards, covering lighting, socket outlets, small power circuits and a wide range of fixed appliances.
These breakers interrupt the line conductor only, ensuring rapid fault clearance while keeping the neutral intact. They are available across a full range of current ratings and tripping curves, making them suitable for both domestic and light-commercial installations with predictable load characteristics.
Single-pole MCBs are used in the majority of consumer units and are the correct protective device whenever only the line conductor requires disconnection under fault conditions.

A single-pole MCB is a miniature circuit breaker that disconnects only the live conductor when a fault occurs. This ensures safe isolation of the circuit under overcurrent or short-circuit conditions while leaving the neutral conductor unaffected.
Single-pole breakers provide fast fault clearance on the live conductor, supporting safe operation and predictable disconnection times on standard single-phase installations. They remain the industry standard for domestic and small-scale commercial work.
B Curve: Trips at 3–5 × rated current; ideal for lighting and general circuits.
C Curve: Trips at 5–10 × rated current; suitable for circuits with moderate inrush, such as small motors or equipment with start-up surge.
All Single-Pole MCBs in this category meet BS EN 60898 and comply with 18th Edition Wiring Regulations when correctly selected based on fault level, circuit design and load characteristics.
Reliable, predictable and widely compatible, single-pole MCBs provide everyday protection across the vast majority of UK circuits. Their modular design, familiar operation and broad rating selection make them a dependable choice for upgrades, rewires and new installations.
