Protek SRCBO B Type Breakers are high-quality Single Module Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) designed to provide complete protection against overloads, short circuits, and earth leakage faults in residential, commercial, and light industrial electrical installations. By combining the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) into a single compact unit, Protek SRCBO B Type Breakers help save valuable space within consumer units and distribution boards while delivering reliable, individual circuit protection.

A B Type RCBO features a B Curve tripping characteristic, meaning it will trip instantaneously at between 3 and 5 times its rated current. This makes it ideal for circuits with low inrush currents, including lighting circuits, domestic socket outlets, office equipment, heating controls, and general-purpose electrical installations. The B Curve characteristic provides fast and dependable protection while minimising nuisance tripping on standard electrical loads.

Protek SRCBO B Type Breakers are available in a range of current ratings and typically provide 30mA residual current protection, helping to reduce the risk of electric shock and improving electrical safety. Designed for DIN rail mounting, these compact single-module RCBOs are suitable for modern consumer units and distribution boards where space is at a premium. They are manufactured to the latest electrical standards, ensuring excellent performance, reliability, and long service life.

These RCBO breakers are ideal for protecting individual circuits in homes, offices, schools, retail premises, workshops, commercial buildings, and industrial control panels. By isolating only the affected circuit during a fault, Protek SRCBOs minimise disruption to the rest of the electrical installation, making fault finding easier and reducing unnecessary downtime.

Whether you are installing a new consumer unit, upgrading an existing electrical distribution board, or carrying out electrical maintenance, Protek SRCBO B Type Breakers offer a dependable, cost-effective solution for comprehensive circuit protection. Their compact design, high breaking capacity, reliable earth leakage protection, and compliance with current wiring regulations make them an excellent choice for professional electricians, electrical contractors, and electrical wholesalers.
