LSiS MC-225a Contactor 225A 3-Pole 110kW 230V AC/DC 2NO 2NC

The LSiS MC-225a is a high-performance 3-pole industrial contactor engineered for reliable power switching in demanding electrical environments. With a rated operational current of 225A and a power capacity of 110kW, this device provides robust control for heavy-duty electric motors and complex power distribution systems. It is equipped with a versatile 230V AC/DC coil, ensuring compatibility with a wide range of control voltages, and features 2 normally open and 2 normally closed auxiliary contacts for flexible integration into automation circuits.

Advantages

This contactor stands out due to its durable construction and high switching capacity, which ensures long-term operational stability in industrial settings. The dual AC/DC coil design simplifies inventory management and installation by allowing the same unit to be used across different control voltage configurations. Its compact 3-pole design facilitates efficient space utilization within electrical cabinets, while the inclusion of multiple auxiliary contacts provides the necessary feedback signals for advanced monitoring and control systems.

Suitable for

• Industrial motor control systems
• Power distribution and switching panels
• Automation and process control applications
• Heavy-duty electrical equipment management

When it may not be suitable

This device is not intended for residential low-voltage applications or circuits that require significantly lower current ratings, as it may be oversized and inefficient for such tasks. It is also not suitable for environments where the ambient conditions exceed the manufacturer's specified temperature or humidity limits without appropriate protective enclosures.

Key specifications

• Rated operational current: 225A
• Power rating: 110kW
• Number of poles: 3
• Coil voltage: 230V AC/DC
• Auxiliary contacts: 2 normally open (NO) and 2 normally closed (NC)

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The contactor is typically mounted on a standard DIN rail or via screw mounting within a control panel. Ensure that the power supply matches the 230V AC/DC coil rating before connecting the control wires to the coil terminals. Connect the main power lines to the primary terminals and integrate the auxiliary contacts into your control logic as required for your specific application.

What to consider before purchase

• Verify that the 225A current rating matches your load requirements.
• Ensure the 230V AC/DC control voltage is compatible with your existing control system.
• Check the available space in your electrical cabinet for the physical dimensions of the unit.
• Confirm that the auxiliary contact configuration meets your feedback and interlocking needs.

Usage recommendations: Regularly inspect the terminal connections for tightness and check for any signs of wear or overheating during routine maintenance intervals to ensure continued safe operation.
