Product information

Description

The LSiS MC-40a is a robust 3-pole industrial contactor engineered for efficient electrical circuit management and reliable power switching. Designed to handle demanding industrial environments, this contactor provides a rated current of 40A and a power capacity of 18.5kW, making it a dependable component for controlling motors and various electrical loads. It operates with a 24V AC control coil and includes integrated auxiliary contacts to facilitate seamless integration into complex automation systems.

Advantages

This contactor stands out due to its high operational reliability and durable construction, which ensures consistent performance even under frequent switching conditions. The inclusion of both normally open and normally closed auxiliary contacts offers enhanced flexibility for control circuit design and feedback monitoring. Its compact 3-pole design allows for efficient use of space within electrical cabinets, while the standardized 24V AC coil voltage ensures compatibility with common industrial control power supplies.

Suitable for

  • Motor starting applications
  • Industrial automation systems
  • Power switching for heating and lighting circuits
  • Control panel integration

When it may not be suitable

This device is not intended for use in high-voltage applications exceeding its rated capacity or in environments with extreme corrosive gases. It is also not suitable for DC power switching applications as it is specifically designed for an AC control coil.

Key specifications

  • Rated current: 40A
  • Number of poles: 3
  • Power capacity: 18.5kW
  • Control coil voltage: 24V AC
  • Auxiliary contacts: 1 normally open (NO), 1 normally closed (NC)

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The contactor is typically mounted on a standard DIN rail or via screw mounting inside an electrical enclosure. Connect the main power lines to the primary terminals and the control circuit wires to the coil terminals. Ensure all connections are tightened to the specified torque to prevent overheating. Once installed, verify the operation of the auxiliary contacts and the coil engagement before applying the full load.

What to consider before purchase

  • Verify that the 24V AC control voltage matches your existing control system.
  • Ensure the 18.5kW power rating is sufficient for your specific motor or load requirements.
  • Check the available space in your control cabinet for mounting.
  • Confirm that the auxiliary contact configuration meets your feedback or interlocking needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of wear or debris accumulation to maintain optimal performance and safety.
