LS UA-100 / AU-100 / AU-100E Auxiliary Contact Block (1a1b), Side Mount for Large Frame MC/GMC Contactors
1. 核心概述 (Overview)
The LS Electric UA-100 / AU-100 / AU-100E Auxiliary Contact Blocks are specialized side-mount accessories designed for large-frame LS MC/GMC series contactors (GMC-125, GMC-150, up to GMC-600). These contact blocks provide a 1 normally open (NO) + 1 normally closed (NC) (1a1b) configuration to expand control circuit capabilities, enabling status feedback, interlocking, and PLC signal transmission for high-power motor control and industrial automation systems.
2. 关键特性 (Key Features)
- 1a1b Contact Configuration: Standard 1NO + 1NC auxiliary contacts for dual signal output, suitable for control and feedback circuits.
- Side-Mount Design: Optimized for side installation on large contactors, preserving front-panel wiring space while expanding control functions.
-
Multi-Generation Compatibility:
-
UA-100: New version for modern large-frame contactors -
AU-100: Original legacy version for older GMC series contactors -
AU-100E: Enhanced version with improved contact performance and durability
-
- High-Current Rated Contacts: Silver alloy contacts with stable performance under industrial control circuit conditions, suitable for long-term use in high-cycle applications.
- IEC/GB Compliant: Meets IEC 60947-5-1 and GB 14048.5 standards for low-voltage control components.
- Quick Snap-In Installation: Tool-free mounting for fast assembly on compatible contactors, reducing panel wiring time.
