Normally Open (NO) Modular Contactors – 230V and 24V

Normally Open (NO) Modular Contactors are vital components in electrical systems, designed for managing and controlling power distribution effectively. Available in 230V and 24V coil voltages, they offer flexibility for various applications in residential, commercial, and industrial settings.

Key Features
  1. Contact Configuration:
    NO contactors remain open when the coil is de-energised, preventing current flow. When energised, the contacts close, allowing current to pass through. This functionality makes them suitable for applications requiring control of lighting, motors, or other electrical loads.
  2. Pole Options:
    • 2-Pole Contactors: Best suited for single-phase applications.
    • 4-Pole Contactors: Ideal for controlling three-phase systems or multiple circuits.
  3. Coil Voltages:
    • 230V AC: Commonly used in residential and commercial installations.
    • 24V AC/DC: Preferred for control circuits and automation systems.
  4. Current Ratings:
    Available in various ratings to match the specific load requirements of your system.
  5. Ease of Installation:
    Designed for DIN rail mounting, these modular contactors integrate seamlessly into electrical panels.
Applications
  • Lighting Control:
    Efficiently manage lighting systems in homes, offices, or industrial facilities.
  • Motor Control:
    Suitable for controlling small motors and other inductive loads, ensuring smooth operation.
  • Heating and HVAC Systems:
    Control electric heating units, underfloor heating, and HVAC systems reliably.
  • Automation Systems:
    Essential for automated machinery and industrial process control.
Compliance with BS 7671:2018+A2:2022

NO Modular Contactors adhere to the IET Wiring Regulations Eighteenth Edition BS 7671:2018+A2:2022, ensuring that they meet modern safety, functionality, and efficiency standards. This compliance guarantees:
