Universal Coil Specification (Applicable for above models)
- AC coil: AC 100–240 V, 50/60 Hz
- DC coil: DC 100–220 V
- Wide‑voltage design tolerates on‑site voltage fluctuation, no need to stock multiple voltage versions separately
Key Product Advantages
- Arc‑isolation enclosed arcing chamber: Prevents arc leakage and reduces electrical safety risks
- Multi‑certification compliance: Passes IEC, UL and CE standards, suitable for exported equipment projects
- Rich expandable accessories: Optional auxiliary contact blocks, mechanical interlocks and other attachments
- Thermal relay combination: Pairing with MT series thermal overload relays realizes overload & phase‑loss protection for motors
Wiring Notes
- For models MC‑330A and MC‑500A, copper busbar connection is preferred for long‑term stable operation under heavy load;
NO = Normally Open,NC = Normally Closedin auxiliary contact description;- All cable cross‑section recommendations are based on conventional indoor laying conditions, adjust specs for high‑temperature or long‑distance laying scenarios

LS (formerly LS Electric) Metasol MC-a Series High-Power Contactor Detailed Explanation
I. Actual Product Information of MC-185a
1. Key Label Parameters
Model: MC-185a, Auxiliary Contact Specifications 2a2b (2 Normally Open + 2 Normally Closed)
Wide Voltage Compatibility of Coil:
AC Coil: {AC 100–240V, 50/60Hz}
DC Coil: {DC 100–220V}, Excellent AC/DC Compatibility
Net Weight: 5kg per unit, Made in Korea; CE and UL International Certifications

2. Appearance Features
The body is marked with the Metasol series logo, three-pole main circuit high-current copper terminals, orange mechanical status indicator buttons, belonging to the heavy-duty industrial contactor category.
II. Common Advantages of the Series
Wide Voltage Coil Design: Similar to MC-185a Consistent voltage: Most models support AC 100-240V and DC 100-220V, eliminating the need to purchase coils of different voltages separately, and facilitating convenient inventory management.
Safety Protection: Enclosed arc-extinguishing structure prevents arc leakage; terminal anti-touch design complies with multiple international electrical standards such as IEC, UL, and CE, suitable for export equipment.
High Expandability: Can be paired with MT series thermal overload relays to form motor protection units; auxiliary contacts, mechanical interlocks, and other accessories can also be added.
Application Scenarios: Heavy-duty motor start/stop, air compressors, injection molding machines, central air conditioning units, high-power power circuits in production lines; original standard components for Korean automation equipment.
III. Practical Selection Tips
Prioritize Auxiliary Contacts: Commonly used is 2A2B; 1A1B, 3A1B, etc., are available for special operating conditions.
Prioritize this AC/DC wide-voltage coil model for better stability under voltage fluctuations.
MC-330A/500A ultra-high current models have larger terminal sizes and require matching copper busbars/cables.
