Why Choose Modular Contactors?
Modular contactors combine innovative engineering, robust materials, and compliance with strict safety standards to deliver exceptional performance. Here’s why they stand out:
- Wide Range of Ratings: From 20A to 125A, these contactors suit various electrical loads.
- Compact Designs: They save space and integrate neatly into modular panels or consumer units.
- Silent Operation: This feature makes them ideal for homes and offices where noise matters.
- High Durability: Built to endure frequent switching and demanding conditions.
- Standards Compliance: Fully certified to BS7671, BS EN 61095, and BS EN 60947-4-1 for reliability and safety.
How Do Modular Contactors Work?
Modular contactors rely on an electromagnetic coil to control electrical circuits effectively:
- Default State: In the Normally Open (NO) configuration, the contacts remain open, preventing current flow. Alternatively, the Normally Closed (NC) configuration keeps the circuit closed until activation.
- Activation: When the control voltage energises the coil, a magnetic field pulls the armature, closing (or opening) the contacts.
- Deactivation: Once the coil is de-energised, the contacts return to their original state, halting (or allowing) current flow.
This simple yet efficient mechanism ensures accurate and reliable circuit management, even under high-demand scenarios.
