Breaker parts and support

The heart of our day-to-day business is in helping our clients to maintain and extend the life of their air circuit breakers. We do this via:

  • routine maintenance (principally UK and western Europe)
  • supply of spare parts, especially STR relay replacements, opening and closing coils and spring charging motors
  • remote support worldwide via telephone, email, photos and video.

We support - and provide new, guaranteed replacement parts - for several leading ACBs which the OEM no longer supports, including the Masterpact M / Square D / Moeller.
