Simplify Your Panel Wiring
c3controls’ IEC and NEMA terminal blocks are both innovative and user-friendly. World-class in quality, they are simple to install and are color-coded for easy circuit identification. From standard feed-through spring clamp or screw clamp to disconnect, fuse holder, and power distribution terminal blocks, we’ve got a solution to simplify your wiring and enhance your panel quality while saving on valuable installation time.
We construct the housing bodies and clamping parts from materials that consistently perform in the most demanding applications. Our housings are molded from unbreakable thermoplastic. And we use metal bodies made from quality zinc plated brass and electrolytic copper for flawless conductivity and minimal corrosion.
Wide Range of Operation
Multiple termination constructions available in screw clamp, spring clamp and miniature rated from 25 – 230 amperes, in sizes from 5mm – 25mm, and come in a variety of styles and colors to ensure that your wires are visually grouped for safety and convenience.
Multiple Wire Sizes
Our IEC terminal blocks accept wires as small as 0.5mm2 (24 AWG) and as large as 120mm2 (4/0 AWG). NEMA terminal blocks accommodate #22 to two #12 AWG wires (0.5mm – 4mm2).
Our corrosion resistant zinc plated clamping system combined with the pre-loaded 302 stainless steel spring clamps hold the wire securely against the current bar and won’t loosen, even in high vibration applications.
Ease of Installation
Our snap-on, rugged DIN rail mounting foot is designed to easily and securely attach terminal blocks.
Wiring to the terminal blocks is made easy by unobstructed access to terminals. The funneled wiring entry with finger safe IP20 terminals simplifies wiring for fast and easy installation. Our spring clamp terminal blocks offer the convenience of top wiring and our screw clamp terminal blocks feature captive terminal screws that will not fall out during wiring and are recessed to avoid accidental contact.
Quick Circuit Identification
Color-coded blocks and terminal marking system allows for fast and easy circuit identification. Blank, custom, and standard markers are available.
Because you can assemble any combination of terminal blocks next to one another on the same mounting rail, you can easily add or remove individual blocks without disturbing adjacent blocks.
Wide Range of Accessories
Accessories such as circuit bridges, end plates, partition plates, and markers, to name a few, make our line of IEC and NEMA terminal blocks a flexible alternative to any feed through wiring or power distribution application.
The Perfect Range of Terminal Blocks
We offer a wide range of IEC and NEMA terminal blocks from 5mm – 25mm in screw clamp, power distribution, and IEC spring clamp that have ratings from 20A to 232A and that meet UL, CSA and CE standards.
Engineered to a Higher Standard
Engineered for durability and easy installation, c3controls’ line of IEC and NEMA terminal blocks deliver easy installation and distinct functionality and reliability in applications exposed to high impact, shock and vibration.
