DD-frame 0,5-400A for AC and DC applications
The DD-frame can also be built with a motorized function for remotely switch the circuit breaker on and off. This is a simple way of designing a cost effective and simple system without usage of contactor or MOSFET-solutions. The solution is very compact and it is and ideal for “hard to reach” applications. It can either be inside an equipment or at a remote telecom site etc.
DD-frame is CE-approved according to IEC/EN 60934 and IEC 60947-2. For UL it is recognized to UL1077 and UL listed to UL489 and UL489A UL-listed for UL 489 and UL 489A. It is also CCC-approved for the Chinese market.
A very powerful but yet compact circuit breaker. The DD-frame range is well suited as a main breaker for battery applications and as distribution breaker for large loads. DD-frame can handle rated current up to 400A when it is delivered as a paralleled DC circuit breaker. Just as the other CBE products from CBI, the DD-frame is built up of several different building blocks, like a “LEGO”. That means, there are many different variables that can be combined to suite your application in the best possible way. Example is, except of obvious options like rated current and time delay, is: handle, terminals, color, printing, auxilliary switch, trip alarm switch etc. The most popular handle is the “Flush-Rocker” handle which is totally flat when the breaker is turned on in order to prevent accidental switching off.
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).
