The WPCUSP440C combines a three-phase Type 2 surge protection device and 40A four-pole MCB in a plastic IP65 enclosure, providing an enclosed surge-protection assembly for installers specifying three-phase systems.

Surge protection and MCB in one enclosure

A dedicated enclosure gives the surge-protection assembly its own place alongside the wider distribution equipment. This listing is the MCB configuration, so you can identify the protection arrangement before ordering.

  • Type 2 surge protection: helps protect connected equipment against transient overvoltages when correctly selected and coordinated.
  • 40A four-pole MCB: provides the assembly's listed overcurrent protective device.
  • Plastic IP65 enclosure: an option where the enclosure specification requires this material and ingress-protection rating.
  • One assembly reference: quote WPCUSP440C for product enquiries and repeat orders.

Check the protection arrangement The MCB provides overcurrent protection. Any required residual-current protection must be provided separately; this product is not the RCBO version.
