BG Consumer Units with SPD Main Switch & RCBOs | Main Switch Circuit Protection

Shop BG Circuit Protection main switch consumer units with integrated Surge Protection Device (SPD) and individual RCBOs — the gold standard for modern domestic and commercial electrical installations. Designed to meet the latest wiring regulations, these consumer units combine overcurrent protection, residual current protection and surge protection in a single, compliant enclosure.

Each unit features individual RCBOs (Residual Current Breaker with Overcurrent Protection) per circuit, meaning a fault on one circuit will not trip the rest of the board — a critical advantage for both homeowners and professional electricians. The built-in SPD protects sensitive equipment against transient overvoltages caused by lightning strikes and power surges, with type 2 surge protection device options available across the range.
