	Low Voltage Circuit Breakers Whether your need is more reliability, increased ratings or improved operator safety, National Switchgear can provide new products that meet today’s challenges. Through computer-aided engineering and custom fabrication, we provide solutions with minimal install time and at a fraction of the cost of replacement switchgear. Upgrade only as much of your switchgear as YOU need.


	l Low voltage power circuit breaker replacements - Using new 600V air circuit breakers with a custom engineered racking system, a new replacement breaker can be offered to the customer as an exact replacement to an obsolete or worn existing circuit breaker
	l New modular switchgear for “tight” spaces or “narrow” access - new switchgear designed to be able to disassemble in smaller units to transport to hard to access places
	l Cell racking system safety upgrades - changes in the type of racking for increased operator safety such as remote racking or thru-door
	l Bus rating upgrades –increase in continuous current rating
	l Short circuit upgrades -increases the breaker and bus support system
	l Vacuum breaker replacements - roll-in interchangeable breakers
	l Vacuum starter conversions - vacuum starters designed to replace breakers used as motor starters
	l Cell conversions - a new breaker and substructure designed to fitinto an older cell or a new cell racking into the old cell to minimize outages
	l Protective Relay upgrades and pre-wired door packages for shorter down time during installation
	l Automation or monitoring additions
	l Switchgear additions –”match and line”


	National Switchgear’s design team models each design in 3D CAD technology pretesting many aspects before making parts. Most of the model inputs directly into CNC machines for greater accuracy significantly reducing the “concept to prototype” time. With these tools we have the ability to accommodate the need of the customer in a timely and cost effective manner. National Switchgear‘s experienced engineers and craftmen are committed to giving you a more exact solution.
