Before a system can act, it has to know what is happening — and it has to be protected when something goes wrong. We engineer the sensors, switches and protection devices that critical infrastructure depends on to detect, isolate and stay safe.
Detection means knowing the state of a system at all times — a door open or closed, a current within limits, a position reached. Protection means acting on that knowledge before a fault becomes a failure — isolating a circuit, breaking a current, securing a connection to earth. Both disciplines come together in the same environments: electrical substations, railway power systems, aircraft and helicopters, and industrial installations where a missed signal or an unprotected circuit is not an option.

Contactless sensors for monitoring doors, hatches and mechanical states, qualified for helicopter and rail applications
Current & Voltage Sensing
Sensors for monitoring electrical parameters in substations and power systems
Auxiliary & Isolator Switches
Configurable switching for electrical substations, with up to 50 contacts and locking by key or padlock
Circuit Breakers & Protection
Magneto-thermic and magnetic protection devices for harsh and demanding environments
Short-Circuiting & Earthing
Equipment for circuit separation, short-circuit and earth connection, designed to electrical substation standards
Long Service Life
Devices engineered for decades of reliable operation in substations and rail systems (MTBF values available on request)
Extreme Environments
Qualified for wide temperature ranges and demanding mechanical conditions
International Standards
Designed and qualified according to international electrical substation and equipment standards
Aerospace-Grade Qualification
Selected switching components approved for use on helicopters and aircraft
A short-circuiting device, a proximity sensor for a helicopter hatch, a switch qualified for nuclear standards — none of these are catalogue parts adapted after the fact. Each was engineered to a specific operating requirement, and each continues to evolve as platforms, standards and environments change.
Detection and protection solutions from the MAFELEC TEAM are in service in railway power systems and door monitoring, in electrical substations and industrial installations, and in selected aerospace and helicopter applications.
