Puzzled by choosing circuit protection devices? Follow these guidelines and your electrical system will fall into place. Is it sufficient to select protective devices based entirely on their ability ...

Featuring UL 1604 Class I, Div. 2 certification (Group A, B, C, and D), the ESX10-T electronic circuit protector combines electronic trip characteristics and active current limitation to allow ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

PolySwitch TRF600-150 circuit protectors are 25% smaller than previous versions and provide resettable overcurrent protection in telephones, fax machines, set-top boxes, security systems, modems, and ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

Figure 1. Two-pole circuit breakers interrupt both neutral and hot wires (Click to enlarge). Figure 2. A typical combination switch and circuit breaker for medical equipment. Figure 2. A typical ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.
