Type A, 100A double pole RCD requires two module spaces within your consumer unit. Offers extra protection against transient surges and reduces unwanted tripping.
Suitable for use when total RCD protection is required to supplement the system earthing and where local 30mA RCDs are used to give additional protection. The time delay RCD will discriminate with the 30mA RCD.
Type 2 SPD suitable for use with Wylex consumer units. DIN rail mounting, single module with status indication and volt free contact for remote monitoring. Suitable for all single phase three wire systems e.g. TN-C-S, TN-S and TT.
