Product General Introduction

Core Technical Advantages

  1. Specially developed for WDK test terminals and WTR disconnect test terminals, accurate matching terminal contour, used for temporary equipotential bridging during circuit testing and commissioning.
  2. Rich pole specifications from 2-pole short jumpers up to 50-pole ultra-long combs, support partial or whole-row terminal group parallel connection.
  3. Standard silver-plated contacts for conventional power/signal circuits; GE gold-plated version effectively prevent contact oxidation, guarantee stable conduction under micro-current weak signal conditions.
  4. N series optimized for continuous bridgeable N-type terminal rows, compatible with long bus distribution test terminal layouts.
  5. Internal high-conductivity copper conductor, low contact resistance; UL94 V-0 flame-retardant housing, independent insulation between poles to prevent cross short-circuit.
  6. Tool-free plug-in design, quick assembly and removal; reusable for repeated equipment testing and maintenance.

Application Scenarios

Matched with Weidmüller WDK test terminals and WTR disconnect test terminals in automation control cabinets, machine tools, power metering and new energy equipment:

  1. Temporary equipotential short-circuit of signal and power loops during factory pre-commissioning and on-site troubleshooting;
  2. Cooperate with disconnect terminals to complete live voltage/current measurement without re-wiring;
  3. GE gold-plated models are preferred for encoder, sensor and other low-current precision signal circuits to avoid measurement error caused by poor contact;
  4. Long multi-pole combs are used for batch testing of multi-channel signal terminal groups to improve debugging efficiency;
  5. High-pole-count 50-pole combs apply to standardized mass-produced cabinets with long continuous test terminal rows.
