RCCBs Type 'DFS4 B-SK'
This range of 'B' Type RCCBs provides a 2A tripping threshold above 2kHz
THIS DEVICE IS RESISTANT TO HIGH LEAKAGE CURRENTS
Each unit has a contact position indicator, in addition to a reset position, which shows whether the device has been switched off manually or tripped due to a fault. The devices accept both pin and fork busbar, the pin terminal having a maximum cross-section of 50mm. The RCCB has a facility to accept a circuit identification label behind a clear plastic window.

RCCBs Type 'DFS4 B+'
This range of 'B' Type RCCBs provides a 420mA fire protection up to 20,000 Hz
THIS GIVES LIMITED EQUIPMENT PROTECTION
Each unit has a contact position indicator, in addition to a reset position, which shows whether the device has been switched off manually or tripped due to a fault. The devices accept both pin and fork busbar, the pin terminal having a maximum cross-section of 50mm. The RCCB has a facility to accept a circuit identification label behind a clear plastic window.
