Expert maintenance, testing, and repair of high tension and low tension circuit breakers — ensuring reliable protection for your electrical systems and preventing costly downtime.
Circuit breakers are the backbone of electrical protection in any facility — they safeguard expensive equipment, prevent fires, and ensure continuity of operations. But like any mechanical and electrical device, breakers require regular maintenance to function reliably when called upon.
HT (High Tension) and LT (Low Tension) breaker servicing involves comprehensive inspection, cleaning, testing, calibration, and repair of circuit breakers used in industrial and commercial electrical systems. This includes Air Circuit Breakers (ACB), Vacuum Circuit Breakers (VCB), SF6 Circuit Breakers, Oil Circuit Breakers (OCB), and Moulded Case Circuit Breakers (MCCB).
At Enervia, we provide end-to-end breaker servicing — from routine preventive maintenance to emergency repairs and upgrades. Our technicians are trained in the latest testing procedures and safety protocols, using calibrated instruments to ensure your breakers meet manufacturer specifications and electrical safety standards.
Low and medium voltage breakers using air as the arc quenching medium.
Medium voltage breakers with vacuum interrupters for superior arc extinction.
High voltage breakers using sulfur hexafluoride gas for insulation and arc quenching.
Medium to high voltage breakers using mineral oil for arc interruption.
Low voltage thermal-magnetic breakers for distribution boards and motor protection.
Modern intelligent protection units with programmable settings and diagnostics.
Scheduled annual or bi-annual maintenance to keep breakers in optimal condition — reducing the risk of unexpected failures and extending equipment lifespan through regular inspection, cleaning, lubrication, and minor adjustments.
Comprehensive testing using calibrated instruments — contact resistance, insulation resistance (IR test), high voltage withstand test, trip time analysis, and operational sequence testing to verify breaker performance against standards.
Emergency repair services for breakers that have failed or tripped due to faults — rapid diagnosis, spare parts procurement, on-site or workshop repair, and testing before re-energization to minimize production downtime.
Adjustment of trip settings, overload curves, short circuit pickup, and time delays based on updated load profiles and coordination studies — ensuring selective tripping and protecting downstream equipment properly.
Complete disassembly, inspection, and reconditioning of operating mechanisms — replacement of worn springs, bearings, linkages, and dashpots, followed by functional testing and adjustment for smooth and reliable operation.
Detailed service reports with test results, observations, and recommendations — including photographic evidence, compliance certificates, and maintenance schedules for regulatory compliance and asset management records.
Factories with heavy machinery, motor loads, and continuous production processes requiring reliable electrical protection and minimal downtime.
Office complexes, shopping malls, hotels, and hospitals with critical loads and tenant safety requirements needing regular breaker maintenance.
Substations, transmission systems, and grid infrastructure operators maintaining large numbers of HT breakers for reliable power supply.
Metro systems, airports, data centers, and large construction sites with critical electrical equipment requiring expert breaker maintenance services.
Schedule your HT or LT circuit breaker maintenance with our expert team — we ensure your electrical protection systems are reliable, compliant, and ready to protect your facility.
