Terminal Blocks : IEC Spring Clamp Connection : Multi-Conductor

The multi-conductor spring clamp terminals offer a reliable solution for multiple wire connections. The terminal eliminates conventional cross connections, looping wires and reliability problems encountered when connecting two wires in one clamp. The terminals provide multiple connection points in the terminal itself, and the possibility of further multiplication of connections with circuit bridges. The multi-conductor terminal blocks can even be bridged to standard feed through spring clamp terminal blocks of same conductor-size.

Product Features

  • Standard grey thermoplastic housing in 5mm, 6mm & 8mm widths, and available in 20A – 50A.
  • WTB2S-W2-12, WTB2S-W4-12, & WTB2S-W6-12 features one termination point on one side and two termination points on the other side.
  • WTB2S-W2-22, WTB2S-W4-22, & WTB2S-W6-22 have two termination points on each side. Bridging facility is at the center of the terminals.
  • 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.
