Shop circuit protection devices for domestic, commercial and specialist installations, including MCBs, RCDs, RCBOs and surge protection. Use the filters to narrow the range by device type, rating and application.
Device selection depends on the circuit design, load characteristics, prospective fault current, required residual-current response and the equipment manufacturer’s instructions.
Quick guide: MCBs provide overcurrent protection; RCDs respond to residual current; RCBOs combine both functions for individual circuits. RCD type, trip curve, current rating and breaking capacity must be selected for the installation.

Start with the circuit design and connected equipment—not a device label in isolation. The protective device must suit the load, conductor capacity, earthing arrangement, prospective fault current and any residual-current characteristics identified by the equipment manufacturer. Installation and verification should be completed by a competent electrical professional to the applicable edition of BS 7671.
Miniature circuit breakers provide protection against overload and short-circuit current. Select the current rating, trip curve and breaking capacity from the installation design and load characteristics.
Residual current devices disconnect when the monitored current imbalance reaches their operating threshold. The correct type and sensitivity depend on the application and expected residual-current waveform.
RCBOs combine overcurrent and residual-current protection in one device. Per-circuit protection can improve fault discrimination and limit disruption elsewhere in the installation.
