Circuit Breakers

Circuit Breakers
We stock residential, commercial and industrial circuit breakers by every major manufacturer and every vintage from the 1940s to today.  Our stock consists of about 50% new breakers and 50% reconditioned breakers with the majority of reconditioned breakers being obsolete (no longer available from the factory).  We feature Cutler-Hammer circuit breakers, GE circuit breakers, FPE circuit breakers, ITE circuit breakers, Siemens circuit breakers, Square D circuit breakers, Westinghouse circuit breakers, and Zinsco circuit breakers.

We stock Molded Case Circuit Breakers (MCCB) and Insulated Case Circuit Breakers (ICB or Power Breakers).  Our breakers undergo a 45 point Quality Control process to ensure that you get the correct part, on time, every time.

Air Breakers

Air Breakers
Our inventory of Air Breakers (ACB) is extensive, ranging from obsolete Federal Pacific to new style Square D.  We offer the latest in RMS technology, and in many cases, can retrofit your existing Thermal-Magnetic air breaker with an electronic trip unit to provide up to date current protection.

Our air breaker inventory is not yet online.  Contact us or call 888-973-2378 to check stock and get pricing now.

Fuses

Fuses
At Best, we supply low voltage fuses and medium voltage fuses for custom applications.  For low voltage applications, we can typically cross over any other manufacturers part number to a Bussmann fuse number.  In medium voltage, we can provide virtually any manufacturer and vintage ever made.

We specialize in large fuse orders and custom fuse application.  Contact us or call 888-973-2378 to speak with a member of our sales team about our fuse offering.

Low Voltage Switchgear

Low Voltage Switchgear
Whether you're looking for an add-to-existing distribution section or a more complex custom distribution lineup, we can help.  We also perform many retrofits for customers, replacing obsolete, irreparable thermal magnetic air breakers with new style electronic trip features and operation.  Often, we can retrofit your existing thermal magnetic air breakers with RMS electronic trip units, bringing you the latest available technology at the lowest possible cost. If all else fails, we can also match sections to your existing gear that will allow you to utilize the latest technology without completely phasing out your entire existing lineups.  Lead time is our specialty - we can get your order filled in less time than our competitors.

Medium Voltage Switchgear

Medium Voltage Switchgear
From load-break switches to full MV lineups, we can quote both your new construction and your add-to-existing medium voltage requirements (from 4kV to 15kV).  Our technical sales engineers are here to help you spec the the more difficult jobs, and we're always able to turn around both quotes and equipment quicker than our competitors.
