RCDs Type 'A'

These RCDs are for use in sinusoidal 50Hz supplies containing "Pulsed DC".
e.g. the DC pulse touches or crosses zero between two pulses.



If this is not the case refer to the
'B' type RCD selection table.



                                                          
The two and four pole ranges extend to 125 amps in all the
standard sensitivity settings. The range includes many variants
including time delay, surge resistant, remote trip......
See RCD Special Variants
All our RCDs have been manufactured to BSEN 61008.
Two & Four pole RCDs 
 
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.
