LS Electric MCT Series AC Contactor & MTT Thermal Overload Relay Kit | 9A-65A, AC220V Coil, Complete Control Set

LS MCP (MCT/MTT) Motor Control Center: AC Contactors 9A-65A + Thermal Relays, AC220V, IEC Certified

1. 核心概述 (Overview)


The LS Electric MCP Series (comprising MCT AC Contactors and MTT Thermal Overload Relays) is a comprehensive, space-saving solution for industrial and commercial motor control applications. This set combines reliable AC contactors (MCT series) with precision thermal overload relays (MTT series) to provide complete protection and control for three-phase motors from 9A up to 65A. The popular AC220V coil voltage ensures compatibility with standard industrial control circuits, making it an ideal choice for pump, fan, conveyor, and machine tool control systems.

2. 关键特性 (Key Features)


🟢 MCT Series AC Contactor (MCT-9 ~ MCT-65)


  • Wide Current Range: Covers 1a (NC auxiliary) and 1a1b (NC+NO auxiliary) models, with rated currents from 9A (MCT-9) to 65A (MCT-65).
  • AC220V Coil Design: High-sensitivity coil ensures reliable pull-in and drop-out under stable AC220V control voltage, with low noise operation.
  • High-Performance Contacts: Silver alloy contacts offer excellent arc resistance, low contact resistance, and long electrical life, suitable for AC-3 (motor) and AC-1 (resistive) loads.
  • Compact Modular Design: Standard DIN rail mounting for easy integration into control panels, with a small footprint to save space.
  • IEC/GB Compliant: Certified to IEC 60947-4-1 and GB 14048.4 standards, ensuring safety and global performance standards.

🔵 MTT Series Thermal Overload Relay (MTT-32/40/65)


  • Matching Protection: Specifically designed to match MCT contactors (MTT-32 for MCT-32, etc.), providing accurate overload protection for motors.
  • Adjustable Current Settings: Ranges include 22-32A (MTT-32), 28-40A (MTT-40), and 34-65A (MTT-65), allowing precise calibration to motor nameplate data.
  • Manual/Automatic Reset: Features both manual and automatic reset options for flexibility in different operational environments.
  • Easy Wiring & Setting: Clear terminal markings and a calibrated adjustment knob simplify on-site setup and maintenance.
  • Trip Indication: Visual trip indicator for quick fault diagnosis, reducing downtime during troubleshooting.
