Our products

It all started with the Hydraulic-Magnetic circuit breakers from CBI which still is our heart and soul, but Emcomp also supply other components for power distributions. Such as power cables, busbar systems, connectors etc. The common factor is the first class quality and resistance to harsh environments.

Battery Breaker Boxes

The hydraulic-magnetic circuit breakers from CBI are well suited as battery breakers and Emcomp offer enclosed solutions for reliable circuit protection. The design ensures quick and easy connection in a very compact enclosure and the standard range consists of wide range of rated currents and connection points but we can also offer customized solutions based on your requirements and specifications. The enclosures are UV-resistant and can be delivered according to IP67 which ensures a wide range of suitable application areas.
RAU Remote Controlled MCB 0,5-300A for AC and DC applications

The CBI DD-frame is a very compact and reliable Hydraulic-Magnetic circuit breaker ideal for battery applications, power supplies and distribution of larger loads in branch protection circuits. For applications including energy storage, battery management and telecom UPS systems, it is an advantage to be able to fully control the status of the MCB; - Remotely switching to OFF and ON, as well as being able to remotely reset the MCB after an electrical fault. A CBI DD-frame can be fitted in remote areas as well as in places where it’s not necessarily easy to access the circuit breaker in the equipment but still have full control in terms of operating the MCB. Using the CBI RAU together with a CBI DD-frame in your application enables you to take your equipment to the next level in terms of remote accessibility, as well as giving the possibility to dramatically reduce maintenance cost and system down time if a non-fatal fault tripping occurs. The RAU enable easy remote control of a complete system and is a way to save cost as well as space. Traditional solutions to remotely enable on/off of a system is contactors and MOSFET solutions. These solutions are costly, require space and also create energy losses. Another benefit for the RAU solution is that you get possibility to also control the circuit breaker itself and by that get the possibility to reset the breaker after an overload or similar noncritical fault. It’s easy to imagine the benefits with this if the fault occurs at a remote location which might take hours or even days to reach. The RAU can also in a simple way maximize the usage of the battery capacity in for instance a telecom site. At a mains failure you can easily prioritize the loads and by that get best possible uptime for the most critical loads. When power is back you can then remotely switch back load by load.
Y13mm DC MCB up to 600VDC 0,5-50A

High DC voltages, like 300-600VDC, is more and more common in power distributions as a way to reduce the amount of copper in cables and busbar systems. Up to now there has been a challenge to find a MCB that in a safe way can handle such high DC voltages. Now the solution to this is the new development from CBI, the Y-series. It is a revolutionary product that is build on the same proven Hydraulic-Magnetic principle like the rest of the CBI products. Meaning that no de-rating is needed due to the ambient temperature. Y-series can handle 300VDC in one 13 mm module and for applications that require 400 or 600 VDC they can be delivered serial connected from factory and is the 2x13 mm wide. If you need to break both plus and minus in your application, the Y-frame can be delivered as a real electrical 2 pole circuit breaker. In that case up to 300 VDC is 2x13mm wide and 301-600 VDC is 2x13 +2x13mm. I.e. total width 52 mm (4x13).
B-frame 0,1-30A for AC and DC applications

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.
QY13mm DC MCB for up to 125VDC 0,1-200A

QY13 is a circuit breaker developed for being a DC product. To safely operate a DC voltage is different from operating an AC voltage. QY range is therefore a dedicated DC circuit breaker with correct marking and relevant DC approvals. Compared to traditional thermal magnetic MCBs we can highlight the following unique features: QY13 keep rated current regardless of ambient temperature. If you have a challenge with high ambient temperatures in your equipment you can rely on that QY13 always keep the rated current. I.e. no de-rating is needed. Like all our Hydraulic-Magnetic circuit breakers it is designed and certified to be loaded at 100% of rated current continuously. QY13 is built with 13 mm modular width instead of 18 mm as a traditional MCB. This means > 30% more distribution points in the same space. Purpose built to work with DC voltages.
QF13mm AC MCB for 230-415VAC 0,1-25A

QF13 is a rail mounted circuit breaker for AC usage but it has two unique features compared to traditional thermal magnetic MCBs. QF13 keep rated current regardless of ambient temperature. If you have a challenge with high ambient temperatures in your equipment you can rely on that QF13 always keep the rated current. I.e. no de-rating is needed. Like all our Hydraulic-Magnetic circuit breakers it is designed and certified to be loaded at 100% of rated current continuously. QF13 is built with 13 mm modular width instead of 18 mm as a traditional MCB. This means > 30% more distribution points in the same space.
