The Wylex 20A 30mA RCBO combines overcurrent protection and earth leakage detection in a single-module design (just 18mm wide), making it ideal for modern consumer units where space is at a premium. With its B tripping curve, this Type A RCD provides reliable protection against overloads and short circuits while detecting dangerous residual currents.
Key features include a test button for compliance with BS7671:2018 18th Edition testing requirements, 2-pole switching (isolating both live and neutral), and a front-operating DIN rail clip that locks in the open position for safer installation and testing. The miniature design allows for 35mm extra cabling room, simplifying wiring within tight spaces.
