• RCDs Type A (Instantaneous)

  For use in 50Hz AC electrical circuits feeding loads which can generate pulsed wave forms on the AC supply.

• RCDs Type A S (Time Delayed)

  Suitable for mains distribution in widely dispersed power supply networks to prevent 'cascade' tripping.

• RCDs Type AC (Instantaneous)

  For use in 50Hz AC electrical circuits feeding loads which do not interfere with the standard AC supply.

• RCDs Type AC S (Time Delayed)

  Suitable for mains distribution in widely dispersed power supply networks to prevent 'cascade' tripping

• RCDs Type B

  Types: DFS 4B Type NK, DFS 4B Type SK and DFS 4B Type B+

  For use in 50Hz AC electrical circuits feeding loads which can generate AC & DC leakage currents. 'B' type RCDs in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents.

• RCDs Type KV

  Surge current resistant up to 3kA (8/20 μs)
