Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips.

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. These wire connections also stand up to vibration and temperature changes.

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.

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.

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

Visually confirm your circuits are working as expected. These terminal blocks have integrated LEDs that indicate if your circuits are powered or not, helping you troubleshoot issues.

Rated IP20, these blocks have recessed terminals to prevent accidental contact with live circuits.

Secure wires to your circuit board without worrying about them vibrating loose or getting pulled out. Also known as Eurostyle terminal blocks, these blocks use screw-clamp terminals to clamp your wire in place.

Quickly disconnect these terminal blocks without having to remove any wires.

Save time when wiring connections in a junction box; these blocks come already installed in an enclosure.

Mount these circuit breakers directly to DIN rail to protect equipment and wiring in an area of your facility from overloads and short circuits.

Add ground fault protection to a circuit to minimize the risk of electric shock to workers and equipment if there is a current leak.

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

With a main breaker installed and main service knockouts, these boxes are the entry point for electricity into your facility and the first step in protecting your electrical systems.

Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series.

Use with Siemens EQ series breaker boxes.

Unlike breakers that trip thermally, these breakers have a hydraulic-magnetic trip mechanism, so they aren’t affected by changes in temperature.

Mount these breakers, also known as supplemental protectors, through panels downstream from a branch circuit breaker to protect a single piece of equipment.

Replace any Edison-base fuse with these resettable circuit breakers.

Protected by a steel enclosure, these switches withstand tougher conditions than switches in a plastic housing. Also known as safety switches, they have quick-make/quick-break action to eliminate arcing and prolong switch life.

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

Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking.

With a housing that’s designed to contain an explosion, these switches are safe to use in areas where ignitable concentrations of flammable or combustible gas, dust, or fibers may be present.

Often used in electrical enclosures, these switches mount directly to DIN rails. They cut power and keep it isolated to stop equipment from starting up during inspection and maintenance.

Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door.

Rated IP69K, these switches are protected from high-pressure and high-temperature washdowns.

Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage.
