LS MT-63 Thermal Overload Relay, Adjustable 24-65A, Compatible with MC-50a/65a Contactor, 3-Phase Motor Protection
1. 核心概述 (Overview)
The LS Electric MT-63 Thermal Overload Relay is a precision-engineered protective device designed to work seamlessly with LS MC-50a and MC-65a contactors, providing reliable overload and phase-loss protection for three-phase induction motors. With adjustable current ranges from 24A to 65A, this relay offers accurate calibration to match motor nameplate currents, preventing overheating and damage caused by overloads or unbalanced phases. It is an essential component for motor control circuits in industrial, commercial, and automation applications.
2. 关键特性 (Key Features)
- Adjustable Current Ranges: Four calibration options to suit different motor ratings: 24-36A, 28-40A, 34-50A, and 45-65A, allowing precise matching to motor specifications.
- Perfect Compatibility: Specifically designed to pair with LS MC-50a and MC-65a contactors for easy mounting and wiring, forming a complete motor control and protection system.
- Dual Protection Functions: Provides both overload protection (via thermal bimetallic elements) and phase loss/phase unbalance protection, preventing motor burnout from abnormal power conditions.
- Manual & Automatic Reset: Features both manual reset (for safety-critical applications) and automatic reset (for non-stop processes) options to suit diverse operational needs.
- IEC/GB Compliant: Certified to IEC 60947-4-1 and GB 14048.4 standards, meeting global safety and performance benchmarks with CE/CCC certifications.
- Trip Indication: Clear visual trip indicator allows quick fault diagnosis, reducing downtime during maintenance.
- Robust Construction: High-grade flame-retardant housing and durable internal components ensure reliable performance in harsh industrial environments.
