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.
T-frame PDU MCB 0,1-30A AC & DC
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 rated voltage is 120/240-277 VAC and 80VDC. It can be delivered in one and 2 pole configurations. Rated current is 0,1-30A and breaking capacity up to 10kA.
The T-frame has a global approval profile including both UL and VDE.
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).
