Professional circuit breaker testers
A circuit breaker is the crucial final link in your security chain. Whether it concerns medium or high-voltage stations, you must be able to rely on a switch to intervene at the right moment. At Control & Protection, we offer the most advanced testing solutions to objectively determine the mechanical and electrical condition of your circuit breakers.

Why is testing circuit breakers essential?
Circuit breakers often remain on standby for years without being activated. That is precisely where the danger lies. Corrosion, hardened grease or wear on the contacts can slow down or block their operation.
By regularly testing circuit breakers, you can identify defects before they lead to catastrophic damage or dangerous arcing situations.
Complete solutions for circuit breaker monitoring
Together with our partner Megger, Control & Protection supplies a wide range of test equipment that complies with the most stringent international standards (such as IEEE and IEC).
- Timing and analysis (switching times): Measure the exact time required for the contacts to open or close. Deviations in milliseconds can already indicate mechanical problems.
- Contact resistance measurement (static & dynamic): High resistance in the main contacts leads to overheating. With our micro-ohmmeters, you can perform accurate static contact resistance (DLRO) measurements. We also offer dynamic resistance measurement (DRM) to inspect the condition of the arc contacts without opening the switch.
- Motion and speed analysis: By measuring the stroke, speed and acceleration of the contacts, you gain immediate insight into the mechanical integrity of the drive mechanism.
![]() MOM3 The MOM3 is a handheld 300 A micro-ohmmeter designed for checking and measuring contact resistances in high-voltage circuit breakers, disconnecting switches (isolators), and busbar joints. | ![]() EGIL200 Circuit breaker time and travel analyser with DualGround™ testing | ![]() EGIL The EGIL circuit breaker tester is intended for circuit breakers with one contact per phase. The EGIL incorporates features commonly found on more complex test systems, but is designed to be smaller, simpler to use and less expensive than other similar test sets. |
![]() ODEN Primary injection testing of protective relay equipment and circuit breakers | ![]() VIDAR The VIDAR vacuum interrupter tester enables you to check the integrity of the vacuum interrupter quickly and conveniently by means of the known relationship between the flashover voltage and the vacuum interrupter. | ![]() BALTO The BALTO Modular DC high current circuit breaker tester was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high speed DC circuit breakers. |
