A very compact circuit breaker for space saving installations and various type of equipment protection. B-frame series can be built in one and two pole configurations. They can also be build as AC as well as DC breaker so you get correct product for your voltage. B-frame is approved to IEC/EN 60934. On the UL side it exist as UL recognized (UL1077) and UL listed to UL489A. B-frame also carry CCC-approval for the Chinese market.
Modular circuit breaker that is suitable as distribution breaker as well as built in protection of equipment. The CBI C-frame range can be built in rated currents from 0,1A to 50A and in 1 to 4 pole configurations. Just as the other CBE products from CBI, the C-frame is built up of several different building blocks, like a “LEGO”. I.e. 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.
C-frame is CE-approved to IEC/EN 60934, UL-approved to UL1077 or listed according to UL489A. It is also CCC-approved for the Chinese market.
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.
The CBI RAU is a factory fitted module that enables the automated switching of the DD-frame circuit breakers. The unit can actuate the circuit breakers both ON and OFF. The actuation of the circuit breaker pole occurs completely internally. The RAU unit is mounted on the left hand side of the circuit breakers and can be connected up to a three pole unit. The RAU connects to circuit breakers with a standard toggle. The circuit breakers can be manually operated when in the remote mode. Two indicators are present on the front face of the RAU. The first is a LED that provides an indication which indicates the mode of operation as well as showing the units status. The second is a color flag indication which indicates the position of the latching mechanism of the connected circuit breakers. The unit has a select switch, providing the ability to specify the operation mode – remote or manual. A signal output provides feedback to the user that there is power on the load side of the circuit breakers. The connection of the control signal is done via a standard connection terminal block, Phoenix 1780002 or equivalent, which is included with the RAU module.
The RAU unit is powered with a DC voltage but it can also be used to control AC circuit breakers.
A low profile circuit breaker. The CBI T-frame has a low building profile but high performance. The mechanism in this series has been rotated 90 degrees in order to suite applications where the power distribution should be as thin as possible. An example is PDU strips. Instead of having the the terminals at the back, like the other front mounted MCBs, the terminals are placed at the side for minimum depth requirement. The CBI T-frame is operated with the characteristic CBI Flush-Rocker handle which is totally flat when the breaker is on to prevent accidental switching off. To even further prevent accidental switching off it can be delivered with a push-to-reset handle where you need to use a tool in order to switch the circuit breaker off. The handle can be delivered in several different colors for best appearance.
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).
