Field Controls 46086402 Switch
The Field Controls 46086402 safety switch is a critical high-limit component designed for multi-voltage applications, supporting both millivolt systems and standard 24V HVAC circuits. This specific model features a fixed 200°F (93°C) set point with a manual reset mechanism, ensuring that the system remains locked out until an technician can investigate the cause of an over-temperature event. Engineered for durability in high-heat environments, the 46086402 acts as a primary spill switch or rollout limit to prevent hazardous operation during flue blockages or downdrafts. The normally closed contact configuration provides reliable circuit interruption, making it a staple for contractors servicing older gas-fired furnaces, boilers, and water heaters where precise thermal protection is mandatory. Its compact footprint and standard mounting holes allow for direct replacement in Field Controls thermal safety kits, maintaining OEM compliance and system integrity during field repairs.
Product Highlights- Dual Voltage Compatibility: Rated for use in both 750mV thermopile and 24VAC control loops.
- Manual Reset Safety: Prevents automatic recycling of equipment to ensure technician intervention after a thermal trip.
- 200°F Temperature Threshold: Specifically calibrated for high-limit sensing in flue and combustion chambers.
- Contractor Grade Construction: Built to withstand the thermal cycling common in atmospheric venting systems.
- OEM Fitment: Designed as a drop-in replacement for Field Controls safety assemblies and specialized gas valves.
Can this switch be used in a power-vented application?
While primarily used in atmospheric venting, it can serve as a limit in any system requiring a 200°F manual reset, provided the mounting location accurately reflects the heat source being monitored.
Will this work with a standard millivolt water heater?
Yes, the 46086402 is designed to handle the low resistance required for millivolt circuits without causing excessive voltage drop.
What causes this switch to trip frequently?
Frequent tripping usually indicates a restricted chimney, heat exchanger issues, or improper draft conditions that must be addressed before resetting.
