Terminal Blocks : IEC Spring Clamp Connection : Feed Through

c3controls WTB2 Series of feed through spring clamp terminal blocks have been designed to meet the strict specifications and standards of UL, CSA, and IEC. Manufactured with a direct mounting foot for 35mm standard DIN rails. Wiring to the terminal blocks is made easy by the IP20 funnel entry design of the housing.

Product Features

  • Wide range available from 5mm – 8mm with ratings from 20A to 50A.
  • Color-coded blocks in 8 colors and terminal markers available for easy circuit identification.
  • Housing is molded out of an unbreakable high quality thermoplastic.
  • Convenient top wiring – the spring clamp is opened with commonly available screwdrivers, enabling the conductor to be easily inserted in the opening of the spring clamp.
  • Our zinc and electroplated clamping yokes and current bars provide superior conductivity, superb corrosion resistance in normal and hazardous environments, and in conjunction with the stainless steel spring clamp are vibration resistant.
  • Pre-loaded 302 stainless steel spring clamps hold the wire securely against the current bar, and won’t loosen, even in high vibration applications.
  • Internal jumpers (circuit bridges) are available for adjacent and alternate terminal blocks, which frees up valuable wiring space and reduces assembly time.
  • Mounting foot designed for “snap-on”, “snap-off” assembly allows for direct mounting on 35mm DIN rails.
  • Accepts wires as small as 0.5mm2 (22 AWG) and as large as 10mm2 (8 AWG), up to 50 amperes.
  • Marking system allows for fast and easy circuit identification. Blank, custom, and standard markers are available.
