Product Description
It provides an adjustable overcurrent range of 12 to 18 A and mounts directly onto LS MC series contactors. With 1 NO + 1 NC auxiliary contacts, screw-clamp terminations and a sealed IP20 body, the MT-32 12-18A offers reliable, arc-free protection. Rated up to 690 VAC at 50/60 Hz and compliant with IEC/EN 60947-1 and 60947-4-1 (CE, CSA, UL, CCC), it is a widely used spare for panel builders and maintenance teams. The LS Electric MT-32 12-18A is a bimetal-type thermal overload relay from the METASOL MT series, built to protect AC motors and circuits against overloads, phase failure, long starting times and prolonged stalling.
Basic Product Information
- Integrated 1 NO + 1 NC auxiliary contacts for alarm and control circuits
- Direct on-contactor mounting with LS MC-9b through MC-40a contactor frames
- Screw-clamp terminals and sealed IP20 structure for safe, easy wiring
- Rated up to 690 VAC, 50/60 Hz with IEC/EN 60947 compliance (CE, CSA, UL, CCC)
- Adjustable overcurrent setting range of 12 to 18 A for precise motor matching
Technical Specifications
Version & Model Difference
The MT-32 family spans multiple current frames (e.g. 9-13A, 12-18A, 15A) sharing the same METASOL footprint and on-contactor mounting but differing in adjustment range and compatible contactor frames. Choose the frame whose current range matches the motor full-load current.
Application Scenarios
- Overload and phase-failure protection for three-phase AC motors
- Motor starters in HVAC, pumps, conveyors and machine tools
- Industrial control panels and distribution boards
- LS RKN 3P+N 40A 30mA Residual Current Circuit Breaker (RCCB)
- LS 40A 30mA RKN 3P+N Residual Current Circuit Breaker (RKN4030)
- LS Metasol MC-12A Magnetic Contactor, AC 220 V Coil
- LS MC-12A 24VDC PLC Controller (MC-12A)
- LS MC-18A 220VAC Magnetic Contactor (MC-18A)
- LS MC-18A 24VDC PLC Module (MC-18A 24VDC)
- LS MC-6A 220VAC Contactor (MC-6A 220VAC)
Frequently Asked Questions
