Product information

Description

The KOOP Elektro IS40-3-04 is a high-performance modular contactor engineered for robust electrical switching within 3-phase systems. With a rated current of 40A and a 230V coil, this device provides a reliable method for managing electrical loads in both residential and industrial environments. Its design focuses on safety and efficiency, ensuring that circuits remain controlled under various operating conditions.

The primary advantage of this contactor lies in its compact modular architecture, which allows for seamless integration into standard distribution boards. By utilizing 4 normally closed (4NC) contacts, the device maintains a default closed state, making it ideal for specific control logic requirements. The construction is durable and built to withstand frequent switching operations, ensuring long-term reliability and minimal maintenance requirements in demanding electrical setups.

Suitable for

  • Control of lighting systems in commercial buildings
  • Management of heating and ventilation circuits
  • Switching of 3-phase motor loads
  • Integration into automated electrical distribution panels

This contactor may not be suitable for applications requiring normally open (NO) contacts, as this specific model is configured exclusively with 4 normally closed (4NC) contacts. Additionally, it is not intended for use in environments exceeding its rated current capacity or in systems requiring specialized hazardous-location protection.

Key specifications

  • Rated current: 40A
  • Contact configuration: 4 normally closed (4NC)
  • Coil voltage: 230V AC
  • Mounting type: DIN-rail
  • System compatibility: 3-phase

To install the KOOP Elektro IS40-3-04, mount the unit onto a standard DIN-rail within your electrical distribution board. Ensure that the power supply is disconnected before making any wiring connections. Connect the control circuit to the coil terminals and the load circuit to the main power terminals, verifying that all connections are secure and tightened to the manufacturer's torque specifications. Once installed, restore power and test the switching functionality to confirm proper operation.

What to consider before purchase

  • Verify that your control logic requires normally closed (4NC) contacts
  • Ensure the 230V coil voltage matches your control circuit output
  • Check that the 40A rating is sufficient for your specific load requirements
  • Confirm available space on the DIN-rail within your distribution board
For optimal performance and safety, ensure that the contactor is installed by a qualified electrician in accordance with local electrical regulations. Regularly inspect the terminals for tightness and check for any signs of overheating during routine maintenance.
