What are PROTEK Single Pole B Type MCBs?

PROTEK Single Pole B Type MCBs (Miniature Circuit Breakers) are high-quality electrical protection devices designed to protect individual electrical circuits from overloads and short circuits. Suitable for residential, commercial, and light industrial electrical installations, these reliable circuit breakers automatically disconnect the power supply when a fault is detected, helping to prevent damage to electrical equipment and reducing the risk of electrical fires.

B Type MCBs are specifically designed to trip when the current reaches between 3 and 5 times their rated current, making them ideal for circuits with low inrush currents such as lighting circuits, socket outlets, heating systems, offices, and domestic electrical installations. They are one of the most commonly specified MCBs for consumer units and distribution boards throughout the UK.

Key Features of PROTEK Single Pole B Type MCBs

• Provides reliable protection against overloads and short circuits.
• B Type tripping characteristic (3-5 x rated current).
• Single pole design for protecting individual live conductors.
• Suitable for domestic, commercial, and light industrial electrical installations.
• Compatible with PROTEK consumer units and distribution boards.
• Available in a wide range of current ratings to suit different circuit requirements.
• DIN rail mounted for quick and simple installation.
• High breaking capacity for dependable fault protection.
• Clearly marked ON/OFF switching position.
• Manufactured to meet relevant UK and IEC electrical safety standards.

Common Applications

PROTEK Single Pole B Type MCBs are commonly installed to protect a wide variety of electrical circuits, including:

• Domestic consumer units.
• Commercial distribution boards.
• Lighting circuits.
• Socket outlet circuits.
• Heating and boiler controls.
• Office electrical installations.
• Retail premises.
• Schools and public buildings.
• General-purpose electrical circuits with low starting currents.

Why Choose a B Type MCB?

A B Type Miniature Circuit Breaker is the preferred choice for protecting circuits that do not experience high inrush currents. Unlike C Type MCBs, which are intended for motors and inductive loads, B Type MCBs provide faster disconnection for standard electrical loads, offering excellent protection for domestic and commercial wiring systems while helping to maintain electrical safety and compliance with the latest wiring regulations.
