Contactor Snubber Switch
40 AMP AC/DC
High-Performance 40A Contactor with AC/DC Coil
The Contactor Snubber Switch 40 AMP AC/DC is essential for electric underfloor heating systems drawing currents above 16 amps.
It allows a single thermostat to safely control high-load heating circuits by switching the main load through the contactor, protecting the thermostat from overload.
Key Applications & Uses
- Switching high-load electric underfloor heating circuits over 16 amps
- Integration with standard thermostats for safe load management
- Domestic, commercial, and industrial underfloor heating systems
- Compatible with both AC and DC control circuits
- Reliable solution for multi-zone heating installations
- Prevents wear and damage to thermostats from high-current loads
Technical Specifications
- Rated Current: 40 A
- Coil Voltage: AC/DC (compatible with standard thermostat outputs)
- Switch Type: Snubber-protected contactor
- Maximum Switching Power: 9,280 W (depending on load and installation)
- Operating Temperature Range: -20 °C to 50 °C
- Mounting: DIN Rail or Surface Mountable
- Dimensions: Approx. 90 mm (H) × 35 mm (W) × 60 mm (D)
- Electrical Protection: Supports integration with RCD or MCB for safety
- Durability: Designed for long-term use in underfloor heating systems
- Warranty: 1 Year Manufacturer’s Warranty
Why Choose This Contactor
This 40 A snubber contactor ensures safe operation of high-load heating circuits while allowing a standard thermostat to control the system efficiently.
Ideal for:
- Large open-plan areas with multiple heating circuits
- Commercial spaces where multiple zones require reliable switching
- Retrofit projects where high-current underfloor heating systems are added to existing thermostats
Installation Guidance
Always connect the contactor to a dedicated power supply and integrate it with suitable RCD/MCB protection.
Ensure wiring complies with local electrical regulations.
Installation should be carried out by a qualified electrician to guarantee safety and compliance.
