RCBOs are a combination of an RCCB and a miniature circuit breaker in a compact design for personnel, fire and line protection. For personnel protection and fire protection, the residual current part of the type AC trips in the event of sinusoidal AC residual currents, type A also trips in the event of pulsating DC residual currents. In addition, RCBOs type F also detect residual currents with mixed frequencies up to 1 kHz. RCBOs with a rated residual current of maximum 30 mA are used for personnel, material and fire protection, as well as for protection against direct contact. Clear and visible conductor connection in front of the rear bus bar facilitates controls
Large and easily accessible wiring space enables easy insertion of conductor in the terminals
The surge current withstand capability of over 1 kA ensures safe and reliable operation
All additional components for miniature circuit breakers can be retrofitted on the right-hand side
