Why use 4 modules when you can use 1?
The Lewden single-module Type B-HP RCBO combines residual current and overcurrent protection in one compact 18 mm device, helping installers save valuable space in the consumer unit without compromising on protection.
And it’s not just about saving space.
• 16A–40A, B & C curve options
• 30mA residual current rating
• 6kA short-circuit breaking capacity
• Bi-directional
• 1 Pole + Switched Neutral
• Designed to operate at higher frequencies, including the enhanced Type B characteristics required for heat pump applications
