1-Pole 10kA Miniature Circuit Breakers (MCBs) – High Breaking Capacity for Professional Electrical Installations
Discover our premium range of 1-pole 10kA miniature circuit breakers (MCBs). These reliable single-pole circuit breakers provide superior protection against overload and short-circuit faults in accordance with IEC/EN 60898-1. Designed for professional use, they are the preferred choice for electrical contractors, construction companies, renovation firms, industrial facilities, research laboratories, and van conversion specialists.
With a 10kA breaking capacity, these MCBs offer significantly higher short-circuit withstand than standard 6kA models. They are ideal for installations near the main supply, in commercial buildings, or in environments with potentially higher fault currents, ensuring maximum safety for cables, equipment, and personnel.
Key Benefits of 1-Pole 10kA MCBs
Our single-pole miniature circuit breakers deliver fast tripping, excellent current limitation, and long mechanical endurance. They are built for daily use by qualified electricians and feature:
- Effective protection of cables and conductors against overload and short circuits
- Easy DIN-rail mounting (35 mm) for quick installation in distribution boards and enclosures
- IP20 protection rating (higher when installed in enclosures)
- High energy limitation class – reduces stress on the entire installation
- Compliance with international standards for residential, commercial, and light industrial applications
Applications of 1-Pole 10kA Miniature Circuit Breakers
1-pole 10kA MCBs are widely used by professional electricians and businesses that demand robust protection in demanding environments. Common applications include:
- Construction and Renovation Companies: Protecting final circuits in new builds, refurbishments, and modernisations of residential and commercial properties. Ideal for safeguarding wiring in walls, ceilings, or trunking systems.
- Electrical Service and Installation Firms: Fast, standards-compliant upgrades or repairs in existing distribution boards and control panels.
- Industrial Companies and Machine Builders: Safeguarding control circuits and auxiliary circuits in production machinery. Meets requirements of EN 60204-1 for machinery electrical equipment (minimum 10kA short-circuit rating often required).
- Research Centres and Laboratories: Precise protection of sensitive test and measurement equipment against unexpected current surges.
- Van and Campervan Conversions: Secure protection of 230V AC circuits in mobile installations, leisure vehicle electrical systems, and custom fit-outs – a popular choice among professional converters for on-the-road reliability.
Using these high-performance MCBs helps reduce downtime, prevent damage to expensive equipment, and ensure full compliance with current safety regulations across all target sectors.

Frequently Asked Questions (FAQ) about 1-Pole 10kA MCBs
What is the difference between a 1-pole MCB and a general circuit breaker?
A 1-pole miniature circuit breaker (also called single-pole MCB or LS switch) protects only the live (phase) conductor. It is designed specifically for overcurrent protection of cables and circuits in final sub-circuits.
When should I choose a 10kA MCB instead of a 6kA model?
10kA MCBs are recommended in commercial buildings, industrial settings, installations close to the main supply, or anywhere the prospective short-circuit current may exceed 6kA. They provide extra safety margin and are often required by standards such as EN 60204-1 for machinery.
Which trip characteristic should I select – B or C curve?
Type B is suitable for resistive loads (lighting, general sockets). Type C is preferred for inductive loads such as motors, transformers, fluorescent lighting, or small machines, as it tolerates higher inrush currents without nuisance tripping.
Are 1-pole 10kA MCBs suitable for industrial use?
Yes. They are commonly installed in control panels, machine switchboards, and production facilities. Their 10kA breaking capacity meets many industrial requirements for reliable protection of control and auxiliary circuits.
Can these MCBs be used in van and campervan conversions?
Absolutely. Professional van converters frequently use 1-pole 10kA MCBs to protect 230V AC circuits in mobile setups, ensuring safe and reliable power distribution during travel.
How do MCBs differ from fuses?
Unlike fuses, which must be replaced after tripping, MCBs can be reset easily after a fault. They maintain consistent performance over their entire service life and do not degrade like fuses.
Do these 10kA MCBs comply with all relevant international standards?
Yes. They are tested and certified according to IEC/EN 60898-1 and carry relevant approvals, ensuring full compliance with low-voltage installation standards (IEC 60364 / VDE 0100 series) for cable and conductor protection.
What advantages do 10kA MCBs offer to construction companies and renovation contractors?
They enable fully compliant installations with a higher safety level, minimise the risk of secondary damage, and simplify acceptance and handover processes for electrical inspectors and authorities.
