The PME relay continuously monitors all three phases at 400/415V
Always pair with downstream RCBOs or RCDs for full system protection
The WFMS/3P is a 125 A metal fuse switch assembly combining a 4-pole main switch with a 3-pole 22 × 58 mm fuseholder for robust three-phase circuit isolation and protection
Complies with BS EN 60947-3 and BS 7671
10kA breaking capacity – protects against high fault currents
20A 4 Pole 10kA MCB C Curve – WKC420C MCBs The PME relay continuously monitorsThe WKC420C is a 20A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three phase + neutral systems. With its C Curve trip characteristic, it is suited to inductive load circuits such as motors, HVAC, pumps, and EV charging sub circuits in commercial boards, EV distribution setups, and solar PV systems. Offering a 10kA breaking capacity, the WKC420C ensures safe overload and short circuit protection while isolating all live conductors and
