Able to handle high inrush current caused by equipment startup, these circuit breakers are suitable for motor and larger transformer applications.

Able to handle high inrush current caused by equipment startup, use these circuit breakers upstream from motors and larger transformer applications.

These magnetic circuit breakers are unaffected by temperature changes and trip when the magnetic field in the coil increases from current overload, so they are suitable for high-temperature environments.

These boxes have a main circuit breaker switch and main service knockouts in the corners. Use with Square D QO series circuit breakers.

Connect these boxes to a main box—they do not have a main circuit breaker switch. Use with Square D QO series circuit breakers.

Install these circuit breakers into Cutler-Hammer CH series breaker boxes.

These magnetic circuit breakers are unaffected by temperature changes so they are suitable for high-temperature environments. They trip when the magnetic field in the coil increases from current overload.

Protect against overload and short circuits in low-voltage automotive and other electronic applications.

These circuit breakers resist vibration better than standard low-voltage DC circuit breakers.

These fuses are suitable for low-voltage automotive and other electronic applications.

These fuses open circuits quickly when surges are detected.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges, such as when starting a motor.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges, such as when starting a motor.

Designed to handle high inrush currents and the initial current cycle unique to transformers, these fuses provide comparable performance with a smaller footprint than standard size fuses.

Smaller than UL Class J fuses, these fast-acting fuses can be used in extra-tight spaces such as meters, uninterruptible power supplies, and variable-speed drives.

These fuses open circuits quickly when surges are detected.

Replace the current-carrying element rather than the entire fuse after the fuse breaks. These fuses are fast-acting.

These fuses open circuits quickly when surges are detected.

With a quicker response than standard fast-acting fuses, these fuses provide the best protection for sensitive electronics.

Compatible with most multimeters, including Fluke.

Also known as dual-element fuses, these fuses withstand current overload for a short time so they won't open when exposed to harmless temporary surges, such as when starting a motor.

These fuses open circuits quickly when surges are detected.

Also known as thermal cut-offs, these fuses prevent equipment from overheating. They work similar to electrical fuses—when the device or environment becomes too hot, the fuse opens and the device turns off.

These fuses have a longer time delay than standard time-delay fuses. Use them in motor applications where the motor is cycled on and off frequently.

Also known as LGR fuses, these fuses open circuits quickly when surges are detected.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges.
