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.
Emcomp’s insulated busbars are especially designed for usage together with CBI Q-range MCBs. Due to the smaller modular width of the Q-range (13 mm) we of course also need to support with busbar systems with the same pitch. The busbars are available in various configurations for 1-3 phases, with or without auxiliary switches. Emcomp’s Busbars for Q-range are available in both straight and 90degree angled versions, with pin as well as fork connection. Usage of Emcomp’s Busbars saves time during assembly as well as gives more even distribution of the current which increase safety as the risk for imbalanced loads in the system decreases.
The ranges of dedicated DC circuit breakers for DIN rail mounting offers new possibilities for DC distributions without vague de-rating rules for applying AC MCBs to DC voltages. For the higher rated currents 80A and above, a proper paralleling bridge is needed for best possible performance. In our portfolio there are paralleling bridges for MCBs with 13, 19 and 26mm pitch. They can be both in straight or in angled version and with connection terminals for different size of open end cable as well as with studs for connection of cables with cable lug. The standard version is untreated copper but in the cases where the application calls for it we can also deliver with surface treatment.

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.
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).
