CBI circuit breakers utilize Hydraulic Magnetic Technology which always carry 100% of rated current with the trip point unaffected by changes in ambient temperatures.

In 1957, CBI Electric invented the highly sensitive residual current device (RCD), which eventually resulted in South Africa being the first country in the world to make the use of RCD’s mandatory.


The development of circuit breakers, from miniature to moulded case circuit breakers, utilises hydraulic-magnetic technology. All of the circuit breakers CBI Electric manufactures employ the hydraulic magnetic principle of operation. This technology boasts two distinct properties; one is the accurate tripping characteristics, and the other is that it is independent of ambient temperature variations.


CBI Electric, perhaps better known in Australia as Heinemann Electric, has a long history that dates back to the 1950’s and early 1960’s and is known for its SF range of products that have been entrenched in Australian mining, rail, industrial and commercial applications.


CBI Electric has products to suit mining, commercial, rail, industrial, solar, telecommunications, automation as well as the unique CBE range for OEM equipment.

The SF RANGE

NEW RELEASE

Remote Actuation Unit for DD Frame Breakers

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 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 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 highlights 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 and system automation. 


CBI can design this product to your needs, whether it be three individual circuits at different current ratings or up to the full capacity using three bridged breakers. These are available in one, two and three pole configurations.

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 is covered by the relevant standard. The full range and technical datasheets are available at www.cbi-electric.com.au.

Lack of Space?
Try Q Range 13mm circuit breakers

Due to the fact that the modular width is13mm instead of the traditional 18mm, you will acheive 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 and thus unaffected by ambient temperature, it allows for the 13mm profile and will always hold rated current. Specially adapted busbars with 13mm modular width, are available in various configurations.

The new 300V, 400V and 600V dc Y frame breakers

CBI have recently released the Y frame, which also has the 13mm profile for telecommunication DC applications. This utilises the hydraulic magnetic technology and takes advantage of the 30% space saving similar to the Q range.

Solar battery storage for off grid, residential and commercial applications

Utilising its hydraulic magnetic technology, CBI Electric has released a range of circuit breakers for the battery storage market which include the stand alone breakers from 80A - 250A at 80Vdc as well as complete with the enclosure, which houses two breakers to safely protect and isolate battery strings from 80A to 250A. 


With the use of hydraulic magnetic technology, you are guaranteed to have no effect on the breakers from ambient temperatures, and when fitted into a MCB shell up to 250A, the customer can save space and enjoy the ease of switching the units on/off when compared against fuse switches and MCCB’s. 


The 250A MCB’s are a four-pole unit which come fitted with copper busbars to achieve the 250A rating and allow for up to three cables to be terminated to the capper bars. The 80A and 100A are two-pole wide units, the 125A and 150A are three pole wide units and the 200A is a four pole unit.


The 250A unit uses a unique 19mm design per pole with the 80A - 200A utilising the unique 13mm design per pole.

POLYBOX Polyethylene Enclosures

These are enclosures that can withstand the harshest conditions and come in a range of sizes and designs, including wall mount, pole mount and floor standing pillars. The range features IP54 enclosures that are heat resistant; have a 15% reduction in heat than conventional enclosures to protect sensitive equipment; are acid resistant; fire retardant; won’t attract lightning strikes; are approximately 30% lighter than standard metal enclosures; and can be recycled up to five times.


CBI’s in-house design and assembly has, to date, completed projects using POLYBOX enclosures for utilities, solar installations, and commercial and industrial projects including temp boards specifically designed and manufactured for the Sydney tunnel projects.


Pole top boxes for utilities allow visible indication of phase fault - this can be seen from ground level and can be easily switched back to the on position once the fault is cleared. 


Pole mounted power quality application for utilities.


Distribution pillars feature a unique anti-gravity three point slam lock for added security and are approximately 50% lighter than conventional pillars.
