Incoming and main outgoing circuit breakers.
Electrical contacts · Repair
We arrange the overhaul and repair of power circuit breakers and disconnectors at a specialist workshop, replacing or reproducing contacts, blades, arc chutes and mechanism parts according to the diagnosis.
Power circuit breakers and disconnectors protect and isolate the incoming supply and main outgoing feeders of an installation. After years of service or after clearing short circuits, their contacts, arc chutes and mechanisms lose performance, and a failure can leave the whole plant without power.
A workshop overhaul allows wear parts to be replaced, parts that are no longer manufactured to be reproduced, the mechanism to be restored and the unit's operation to be verified, extending its service life without replacing the existing switchgear.
Assessment of the condition of contacts, blades, arc chutes, mechanism and plug-in parts.
Main and arcing contacts, disconnector blades and contact plates, tulip contacts, springs and mechanism parts.
Functional check of the unit before it is returned.

Feasibility, materials, dimensions and tolerances are confirmed for each part number after reviewing drawings, samples or equipment data.
Incoming and main outgoing circuit breakers.
Medium- and high-voltage disconnectors and circuit breakers.
Power supply and auxiliary services switchgear.
Technical buildings, data centres and hospitals with high continuity requirements.
Frequency depends on the manufacturer, the number of operations, short-circuit interruptions and the environment. We recommend following the manufacturer's maintenance plan and inspecting the unit after any short-circuit trip.
Yes, in many cases. If a part such as a blade or contact plate is no longer available, we assess reproducing it through reverse engineering.
Yes. On withdrawable circuit breakers the tulip contacts are also inspected and replaced if necessary.
Make, model, rated current, photographs of the rating plate and the unit, and a description of the problem.
Tulip contacts, contact clips and contact fingers for withdrawable circuit breakers, disconnectors and switchgear panels.
