Lewden 40A Bidirectional RCBO | Type A, B Curve, 30mA | Compact DIN Mount
The Lewden 40A Compact Bidirectional RCBO offers superior circuit protection for modern electrical installations, combining overcurrent and residual current protection in a single, space-saving device. Specially designed to accommodate contemporary energy technologies, this RCBO is ideal for use in systems integrating EV chargers, solar PV generators, and energy storage units.
This unit provides reliable bi-directional current protection, meaning it remains effective regardless of the direction of current flow. This feature makes it particularly suitable for hybrid systems that generate and consume energy interchangeably. Whether installed in domestic, commercial, or light industrial environments, this RCBO delivers dependable protection and meets the latest safety standards.
Its compact, reduced-height profile also frees up valuable space within consumer units or distribution boards, helping installers achieve neater and more manageable wiring arrangements.
Key Features
