Modular Contactors – Normally Open (NO) and Normally Closed (NC) for 230V and 24V Systems

Modular Contactors, available in Normally Open (NO) and Normally Closed (NC) configurations, are essential components in electrical systems. They provide reliable control for power distribution in residential, commercial, and industrial applications. With options for 230V and 24V coil voltages, these contactors cater to a wide range of electrical needs.

Key Features of Modular Contactors
  1. Contact Configurations:
    • Normally Open (NO):
      Contacts remain open when the coil is de-energised, preventing current flow. When energised, the contacts close, allowing current to flow. Ideal for applications like lighting and motor control.
    • Normally Closed (NC):
      Contacts remain closed when the coil is de-energized, allowing current flow. When energized, the contacts open, interrupting the flow of current. Suitable for fail-safe systems and circuits requiring interruption when powered.
  2. Pole Options:
    • 2-Pole Contactors: Perfect for single-phase systems or smaller circuits.
    • 4-Pole Contactors: Designed for three-phase systems or controlling multiple circuits simultaneously.
  3. Coil Voltages:
    • 230V AC: Commonly used in residential and commercial applications.
    • 24V AC/DC: Ideal for low-voltage control circuits and automation systems.
  4. Current Ratings:
    Offered in various current ratings to accommodate diverse electrical loads.
  5. Mounting and Compatibility:
    Modular DIN rail mounting allows for easy installation and integration into electrical panels.
Applications of Modular Contactors
  • Lighting Systems:
    Manage lighting circuits efficiently for residential, commercial, or industrial purposes.
  • Motor Control:
    Control small motors and other inductive loads with precision.
  • Heating and HVAC Systems:
    Regulate electric heaters, underfloor heating, and HVAC systems for optimised performance.
  • Automation and Process Control:
    Essential for automated machinery and industrial control applications.
Why Choose Modular Contactors?
  • Flexibility:
    Both NO and NC contact options provide tailored solutions for specific control needs.
  • Reliability:
    Designed to handle frequent switching and ensure long operational life.
  • Ease of Installation:
    Modular design allows for quick and seamless DIN rail mounting.
  • Standards Compliance:
    Fully compliant with IET Wiring Regulations Eighteenth Edition BS 7671:2018+A2:2022, ensuring safety and performance.
Compliance with BS 7671:2018+A2:2022

Modular contactors meet the stringent requirements of the IET Wiring Regulations Eighteenth Edition BS 7671:2018+A2:2022, offering:

  • Safety: Reduced risk of electrical hazards, including fire, overheating, and electric shock.
  • Efficiency: Supports energy-efficient operations in modern electrical systems.
  • Reliability: Consistent performance under various load and environmental conditions.
Selecting the Right Modular Contactor

When choosing the right contactor, consider the following:

  • Load Type: Match the contactor’s current rating to your specific load (e.g., resistive or inductive).
  • Contact Configuration:
    • Choose NO contacts for circuits that need to be activated when energised.
    • Opt for NC contacts for systems requiring interruption upon energisation.
  • Number of Poles: Select 2-pole or 4-pole options based on your system’s requirements.
  • Coil Voltage: Ensure compatibility with your system’s control voltage (230V AC or 24V AC/DC).
