LS UA-1 UA-2 UA-4 Auxiliary Contact Block, Side/Top Mount, NO/NC Contacts for Contactor Control Circuits

1. 核心概述 (Overview)


The LS Electric UA Series Auxiliary Contact Blocks are modular accessories designed to expand the control and signaling capabilities of LS MC/GMC series contactors. Available in side-mount (UA-1) and top-mount (UA-2/UA-4) configurations, these contact blocks provide additional normally open (NO) and normally closed (NC) contacts for auxiliary circuits, enabling functions such as status indication, interlocking, and PLC feedback in motor control and automation systems.

2. 关键特性 (Key Features)


  • Modular Expansion: Adds auxiliary contacts to LS MC/GMC contactors without modifying the main contactor, supporting various combinations: 1a1b, 2a, 2b, 2a2b, 3a1b, 4a, 4b.
  • Flexible Mounting Options:
    • UA-1: Side-mount 1a1b (1 NO + 1 NC) contacts for space-saving side installation.
    • UA-2/UA-4: Top-mount contacts (up to 4 poles) for front-facing wiring and easy access.

  • Reliable Contact Performance: Silver alloy contacts ensure stable signal transmission and long service life in low-voltage control circuits.
  • IEC/GB Compliant: Meets IEC 60947-5-1 and GB 14048.5 standards for low-voltage control circuit components.
  • Quick Installation: Snap-on design for fast tool-free mounting on compatible LS contactors, simplifying panel assembly.
  • Wide Compatibility: Designed for use with LS MC/GMC series contactors (MC-9 ~ MC-100A), forming a complete motor control system.
