A single row of terminals fits in narrow spaces.

Customize these blocks’ wiring as your application changes. They come with jumpers that connect terminals on the same block, either across or next to one another.

Made of ceramic, these blocks withstand high-temperature applications that reach up to 1110° F such as ovens and furnaces. They have recessed screws to reduce the chance you’ll cause a short by accidentally connecting two circuits with a screwdriver or other tool.

No need to tighten or loosen any screws—these terminals lock your wiring in place with spring clamps.

Quickly troubleshoot or change wiring without any tools. These terminal blocks have a lever clamp that you flip up to insert wiring and flip down to lock it in place.

One of the connections on these terminal blocks is a socket instead of a traditional terminal, making it easy to swap out equipment or change your wiring even in small enclosures. Instead of having to attach wire inside the tight space of your enclosure, you can wire a connector wherever it’s easiest and then plug it into the socket.

Use with DIN 2 rail. Add as many circuits as you need with these terminal blocks and accessories.

Solder the pins on these blocks directly to your circuit board and connect the screw terminals to stripped wires, ring terminals, or spade terminals.

Inspect the terminal block and wiring without opening the cover.

Blocks mount in a cutout and have terminals on both sides.

Also known as supplemental protectors, these circuit breakers mount directly to DIN rail downstream from a branch circuit breaker to protect a single piece of equipment.

An electronic trip mechanism makes these circuit breakers fast, precise, and consistent. They continuously monitor current and trip at a precise value compared to the much wider current range in traditional thermal-magnetic breakers.

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

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

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

Protect an area of a facility that has high-powered equipment using up to 600V AC or 750V DC and 600A of current.

Small enough to fit in tight spaces, these circuit breakers mount through panels and are UL 489-rated for branch circuit protection.

Built to resist vibration and corrosion in harsh environments, these circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications.

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

A raintight NEMA 3R rated enclosure protects these switches outdoors.

The IP66 rated housing not only shields these switches from washdowns but also makes them durable enough to be mounted outside of an electrical panel.

Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall.

Stop battery drain and prevent the theft or unauthorized use of equipment by disconnecting batteries when not in use.

Prevent motors and other equipment from overheating or failing from not having enough voltage. When the supply voltage falls below 35% of the rated voltage, these switches will automatically turn off to protect the circuit from undervoltage.

Keep power running while you access your enclosure. Unlike standard enclosure disconnect switches, which shut off power as you open your enclosure, these have an override function.

Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow.
