Specialist in low-voltage circuit breakers
Independent expertise. From maintenance and technical condition assessment to testing, troubleshooting, and retrofit.
The critical link in low-voltage distribution
Whether it’s an ACB or MCCB, the circuit breaker forms the backbone of your low-voltage installation.
- Air circuit breakers (ACB)
- Molded case circuit breakers (MCCB)
- Fixed and withdrawable types
- Electronic trip units
Maintenance is more than cleaning and lubrication
Reliable operation requires insight into the mechanical and electrical condition of every crucial component.
To measure is to know
"A low contact resistance alone does not always mean the main contact of the circuit breaker is in good condition."
Targeted inspections and combined testing provide a better-founded view of technical condition and the appropriate next step.
- Contact resistance measurement
- Insulation resistance measurement
- Primary current injection
- Secondary current injection
- Trip unit testing
- Circuit breaker timing
- Pole synchronism
- Coil current analysis
- Functional testing
Old or obsolete does not automatically mean complete replacement
Using retrofit solutions, existing installations can be modernised to be reliable again, without replacing the complete main switchboard. We offer a wide range of outcomes.
Manufacturer-neutral assessment
Technical assessment starts with the exact manufacturer, type, configuration and application. Experience with a manufacturer does not automatically imply support for every product family.
