Cabur Terminal Blocks and Interface Modules: Selection and Panel Wiring Guide

Author: EFFSEN AUTOMATION | HONGKONG | Date: 2026-11-10

What Cabur Offers

Cabur supplies DIN-rail terminal blocks, interface modules, relays and marking systems for electrical panels and machine wiring. Their range spans screw and spring clamp terminals, fuse holders, disconnect terminals and signal conditioning.

Selecting Terminal Blocks

  • Connection type: Screw clamp for general duty; spring (push-in) for vibration resistance and faster wiring.
  • Current and cross-section: Match the rated current and conductor size (e.g. 2.5 mm², 6 mm², 16 mm²) to the circuit.
  • Function: Choose ground, fused, disconnect, double-level or sensor/actuator terminals as needed.
  • Approvals: Confirm UL/IEC ratings for your market and panel standard.

Interface Modules and Relays

For PLC I/O, interface relays and solid-state modules isolate and boost signals; pick coil voltage (24 V DC common), contact rating and pluggable vs fixed. Use diode or RC suppression on the coil side to protect the PLC output.

Installation Tips

  1. Snap terminals firmly onto a standard 35 mm DIN rail and end-stop them.
  2. Apply consistent torque on screw types; over-tightening strips the clamp.
  3. Use Cabur marking tags and grouping separators for maintainability.
  4. Derating: do not run a terminal at its absolute maximum in hot enclosures.
