Circuit Protection
Emcomp’s hydraulic-magnetic circuit breakers provide safe and reliable protection against overload and short-circuit. The hydraulic-magnetic design enable compact circuit breakers that withstand harsh environments. Ideal for a wide range of applications.
Connection terminals
For an easy and reliable way be able to connect cables and busbars in a system is not always easy. Therefore we are utilizing sub-components from some of our circuit breakers and supply as separate components. The advantage is that they are designed to create reliable connections and they are easy to deliver in large quantity to an attractive price picture.

why choose hy-mag circuit breakers?
Always keep rated current regardless of temperature
The main advantage of HY-MAG circuit breakers over traditional thermal-magnetic MCBs is their insensitivity to ambient temperature variations. HY-MAG breakers maintain their rated current capacity from -40°C to +85°C, while thermal-magnetic MCBs only perform reliably at room temperature.
At around 30°C, thermal-magnetic MCBs can only handle about 75% of their rated current, requiring de-rating. This de-rating often leads to the need for higher-rated (and more expensive) MCBs, as well as increased costs for cables and busbar systems, along with reduced accuracy in applications.
Advantages of HY-MAG
Circuit Breakers
Immediate reset after tripping
Unlike thermal magnetic MCBs, HY-MAG breakers can be immediately reset after an overload.
Dedicated products for AC and DC
HY-MAG breakers are specifically designed for either AC or DC applications to handle differences in breaking currents and prevent arc extinguishing issues.
Energy efficiency
HY-MAG breakers have about 45% lower internal resistance than thermal magnetic MCBs, reducing energy loss and costs.
No aging of the sensing device
HY-MAG’s sensing mechanism is hermetically sealed, avoiding exposure to air, humidity, and pollution, ensuring long-term reliability.
Worldwide approvals
HY-MAG products meet high certification requirements according to both European (IEC 60947-2) and American standards (UL489/UL489A or UL1077).
