Residual Current Circuit Breakers
This very modern range of RCDs has many technical improvements over previous models. We have incorporated a new latch mechanism as well as new tripping and transformer technology.
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 RCD has a facility to accept a circuit identification label behind a clear plastic window.
The two and four pole ranges extend to 125 amps in all the standard sensitivity settings. The range includes many variants such as time delay, surge resistant and pulsating DC. All our RCDs have been manufactured to BSEN 61008.
