Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

New models are made of thermo-plastic material that has been branded with material identifications for easy recycling. Older models are being phased out. Mitsubishi Electric Automation, Inc., ...

OMICRON's CIBANO 500 is the first 3-in-1 test system to combine a precise micro-ohmmeter, a multi-channel timing analyzer, and a powerful coil and motor supply in a single, lightweight device (20 ...

A 240-volt service powers heavy-duty appliances like ovens, air conditioners, water heaters and electric dryers. If something goes wrong in that panel, it may cause those systems to fail, damage the ...

THE Electrical Research Association has recently reported an interesting development which has taken place in connexion with its programme of research on gas blast circuit breakers. Normally the ...

Circuit breakers are at the heart of every modern power system. To ensure the systems are properly protected, it’s essential the breakers should operate correctly when called upon to do so. This means ...

Table 100.19 from ANSI/NETA MTS-2011 provides recommended test voltages for proof testing and field testing medium-voltage power circuit breakers and switchgear. These three tests should be in your ...

Gladiator miniature circuit breakers offer optimum and efficient protection for branch and control circuits up to 63 amps. The Gladiator GMCBU series is available with B, C, or D trip characteristics ...

Thermal-magnetic circuit breakers contain two different switching mechanisms, a bimetal switch and an electromagnet. The bimetal serves as a means of handling overcurrents. The bimetal typically sits ...
