Our solutions are available in draw-out or fixed mounted designs with main bus continuous current ratings from 600 A to 5,000 A, up to 100 kA symmetrical short circuit current, and voltage ratings up to 600 V. 

Many enclosure options are available, including NEMA 1, NEMA 3R or Stainless Steel. CO7 Technologies Low Voltage Metal Enclosed Switchgear features the latest in distribution and control technology. Our design and manufacturing expertise allow us to offer power circuit breakers, metering, and monitoring systems from all major manufacturers, resulting in endless options for custom distribution and control configurations. We also maintain our own CSA/UL files, so you can be assured that you have selected the safest, most reliable, and effective solution available.

Our Arc Resistant Low Voltage Switchgear is designed to protect your personnel and equipment from the destructive energy and force of an arc flash incident. Our ArcRes Switchgear utilizes specially designed ducting to safely exhaust any arc flash incidents out of the area and away from your personnel and equipment. ArcRes Low Voltage Switchgear is designed with the latest power circuit breaker and solid state trip unit technology with continuous current capacity up to 5,000 A, interrupting rating of 100 kAIC and voltage ratings up to 600V.

This innovative proprietary concept of aluminum profiles eliminates the inaccuracies associated with manufacturing conventional steel panels, while offering superior strength and flexibility. The various shapes of extrusions and molded corners provide a multitude of options, reducing the reliance on fasteners and other accessories while ensuring accurate self-aligning assemblies.


Features and benefits


Aluminum frame: Eliminates Eddy currents in the structure while providing outstanding properties in terms of rigidity, accuracy and continuity of supply.


Aluminum panels and steel: Depending on the application and customer needs, a wide variety of finishes and colors are available.


Flexibility and Strenght: Compared to conventional steel structures, aluminum extrusions not only offer superior strength but also excellent flexibility, making them highly adaptable for special arrangements.


Continuity of masses: The properties of aluminum, in terms of conductivity, provide increased security level of the structure, by directly linking the modules at the point of primary mass allowing equipotentiality across the equipment.


High reliability in & out: Accuracy and anti-corrosive properties of aluminum extrusions can offer a wide range of quality products designed for indoor and outdoor use.


Internal arcs resistant: We offer a wide range of products that have undergone certification testing for resistance to internal arc type 2C, as prescribed by ANSI / IEEE C37.20.7.


Retrofit: The concept is ideal for modernization and replacement. The freestanding structure is easily adaptable to accommodate several types of circuit breakers, disconnectors, and other electrical components.


38 kV – 5000A Capacity: The concept is used for a wide range of products (available from 480 volts to 38 kilovolts). Depending on the needs and applications, different designs are available for current values ​​up to 500A.


Fast Turn Around: The MODU-AL greatly reduces the production time and allows the quickest turn around on the market.

Universal Cradle:

CO7 Technologies developed a unique breaker mechanism that brings:

Increase SAFETY for operators
EFFICIENCY due to its ease of use.
ADAPTABILITY to mee your needs.

Main Features:

  • Three distinct positions: Connected, Test and Disconnected

  • Fully integrated with the circuit breaker and each mechanism is operated individually

  • Operates without special handling with minimum effort

  • Can be operated manually or remotely (with motorized option)

  • Even with the motorized option, it is possible to operate it manually, at any times, without special handling, effortless and safely.

  • Completely adaptable to meet the customer’s needs

  • Adapted to the majority of available circuit breakers on the market

  • Complies with CSA standards for switchgear inside use

  • Can be retrofitted into the vast majority of the medium voltage switchgear of CO7 Technologies already in service

Technical characteristics:

  • Power supply: 120 Vc.a. or 125Vd.c., 5A

  • Torque required to move the circuit breaker in manual mode: < 6.8 N.m (5 lbf.pi).

  • Motor maximal torque: 129.6 N.m (95.6 lbf.pi) (motorized option).

  • Double position check: by encoding and limit switches

  • The Mechanism is protected by a motor drive overload protection
