Possibly the coolest circuit breaker on the market

With no derating or affect from ambient temperature variations using Hydraulic Magnetic Technology.

Making use of our energy efficient Hydraulic Magnetic Technology, our Circuit Breakers always carry 100% of the rated current with the trip point being unaffected by the changes in the ambient temperature. With products to suit comms, solar, utilities, rail, defence and mining the range also includes the unique CBE range for OEM equipment.

The CBE range

The CBE range boasts a wide selection of circuit breakers for equipment in the B, C, and DD FRAME and also includes the 13mm narrow profile QY and QDC ranges available for AC and DC applications. These products can be customised to a customer’s needs and individual specifications assuming the specification falls within the relevant standard. The full range and technical data sheets are available at our web page.

Lack of Space? Q Range 13mm Circuit breakers

Due to the fact that the modular width is 13mm instead of the traditional 18mm, you will realize a space saving of more than 30% in the same cabinet size. This is ideal if you are going to upgrade existing equipment, equally so if you would like to fully optimize and reduce the dimensions on a new design. More compact dimensions are often associated with higher temperatures, but as the Q-range is hydraulic magnetic the trip point is unaffected by ambient temperature thus allowing for the 13mm profile, it will always hold rated current. Specially adapted busbars with 13mm modular width are available in various configurations.

Telecommunications: The new 300V, 400V and 600V DC Y frame breakers

Within the CBE range of products we have recently released the Y frame also in the 13mm profile for Telecommunication DC applications again utilizing the Hydraulic Magnetic technology and taking advantage of the 30% space saving as per the Q range.

Solar battery storage: For off grid and residential and commercial applications

Utilizing our Hydraulic Magnetic technology we have released a range of Circuit breakers and enclosures for the Battery Storage market. With a range from 80A to 250A at 80Vdc this range is available complete with enclosure or sold separately to fit to customers’ individual cabinet requirements. The 250A unit uses a unique 19mm design per pole with the 80–200A utilizing our unique 13mm design per pole. 80–100A 2 Pole, 125–150A and 200A 4 Pole. The complete enclosure houses 2 breakers to safely protect and isolate battery strings, the customer can save space and ease of switching against standard fuses or MCCBs.

Remote Actuation Unit for DD FRAME MCBs

The Remote Actuation Unit (RAU) is a factory fitted module that enables the automated switching of 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 to up to a three pole unit. The circuit breakers can be manually operated when in the REMOTE mode. Two indicators are present on the face of the RAU unit. The first is an LED that provides an indication of the mode of operation as well as showing the unit’s operational status. The second is a colour 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 unit comes with a universally standard connection terminal. For DC circuits up to 300A and AC circuits up to 100A. The RAU has an operating voltage range of 15Vdc to 80Vdc. Applications include battery storage, Telecommunications, Railways, Solar, System Automation. At CBI we can design this product to your needs whether it be 3 individual circuits at different current ratings or up to the full capacity using 3 bridged breakers. Available in 1, 2 and 3 pole configurations.

POLYBOX Polyethylene Enclosures
