What Is a Modular Contactor?
A modular contactor is an electrically controlled switch that allows you to remotely control circuits, often via timers, sensors, or BMS (Building Management Systems). Unlike standard relays, they are designed to handle higher currents safely, making them suitable for both residential and commercial use.
Applications
- Lighting control – switch multiple lighting circuits from a single point. Example: 2-Pole Modular Contactor.
- Heating systems – control underfloor heating, boilers, or immersion heaters.
- EV charging – manage load balancing and timed charging setups. See also EV Consumer Units.
- Automation – integrate into smart home or commercial building controls.
Buying Considerations
- Current rating – select based on load (e.g. 20A, 25A, 40A)
- Poles – single, double, or four-pole depending on circuit design
- Noise level – “silent” or low-noise models are preferred for residential installs
- DIN rail fit – ensure compatibility with your consumer unit or board
FAQs on Modular Contactors
What’s the difference between a relay and a contactor?
A contactor is designed for higher current switching and safer long-term operation, while relays are typically for low-current control circuits.
Do modular contactors comply with the 18th Edition?
Yes – all modular contactors in our range are BS EN certified and compliant with UK wiring regulations.
Can I use a modular contactor for EV charging?
Yes – modular contactors are often used for load management and scheduled charging in EV installs.
