New MagVac Magnetic Latching Medium-Voltage Breakers Guaranteed for 30,000 Open-Close Operations with 5-Year Warranty

  (January 28, 2013)

Deer Park, TX (PRWEB) January 28, 2013

Circuit Breaker Sales & Repair and CBSMagVac are proud to introduce the MagVac line of medium-voltage circuit breakers (MVCBs), which combine vacuum interrupter technology with linear magnetic latching actuators to eliminate more than 100 points of failure from traditional vacuum-interrupter-based MVCB designs.

Designed to help solve medium-voltage breaker maintenance issues for utilities, industrial and processing industries, and commercial facilities, MagVac uses three compact monostable magnetic actuators in line with the vacuum interrupters to eliminate traditional spring/crank/lever operating mechanisms. The result is a medium-voltage breaker guaranteed to last five times longer than most common MVCBs on the market.

The MagVac has virtually no moving parts, explains Lee Heine, President of Circuit Breaker Sales & Repair and CBSMagVac. By removing more than 100 moving parts in the latching assembly, we reduced the points of failure for the break to nearly zero and essentially eliminated the need for periodic maintenance. Imagine a 5KV or 15KV breaker with no charging motor, no closing or trip coils and no springs that directly replace your existing medium-voltage breakers with no cell modifications. Thats MagVac, and it is stronger, lighter and more durable than the original air breakers and vacuum retrofits.


MagVacs magnetic latching design delivers standard break times of less than three cycles and as low as one cycle for special applications. State-of-the-art compact vacuum interrupters are maintenance free, eliminating the need for removal or adjustment. Each MagVac breaker also comes with six NO contacts, six NC contacts and a visual position indicator.

An ANSI/IEC/BG-tested Indoor Switching Module (ISM) simplifies interlocking through an integrated manual trip lever at the rear of the MVCB that blocks the unit both electrically and mechanically. Optional mechanism operated cell (MOC) switches are available through CBSMagVacs innovative MOC Actuator Control System (MACS). The MACS is a patented MOC solution designed to reposition the switchgear independent of the MagVac magnetic actuator. MACS eliminates the possibility of breaker stalls and requires no cell modification.
