RCCBs Type 'A - Time Delay'
These RCCBs 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 RCCB selection table.
Suitable for mains distribution in widely dispersed power supply networks
to prevent 'cascade' tripping         (Download the Selective Tripping Time Chart)
e.g.
* Camping sites * Marinas * Allotment sites * Exhibition grounds
Time delay RCCBs will in most cases protect the cables from the main distribution to the sub-distribution points
   
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.


All our RCCBs have been manufactured to BSEN 61008.
