Terminal Blocks

Available58 products
Terminal blocks mount on DIN rails, channels, or panels to distribute power or ground to one or more components within an enclosure. Also known as connection terminals, they help keep wiring circuits tidy inside confined spaces such as electrical panels to make them easily identifiable and accessible for troubleshooting. Their input and output terminals are connected by a busbar within their insulated frame and have mechanical clamps that compress the conductors to hold and splice them. Terminal blocks allow for quick termination and disconnection of wires with the use of a screwdriver.

Grounding Blocks

Grounding Blocks
These grounding blocks mount onto DIN rails to terminate ground connections and safely discharge excess electricity within an enclosed panel. Also known as earth terminal blocks, they have yellow and/or green housing and are secured to DIN rails using a mechanical screw-clamp. Once connected, the DIN rail acts like a busbar and distributes a ground connection to other terminals touching the same rail.

Circuit Protection Blocks

Circuit Protection Blocks
These blocks provide circuit protection from power surges or short-circuiting. They have an overcurrent protection device (OCPD) that cuts off the circuit's power if it encounters abnormal conditions to protect components downstream from damage.
