Value Brand 6UED1 Limit Rollout Manual Reset Opens 350°F

SKU CH-6A3W-4VKBQ

A snap-disc limit control with manual reset opens on temperature rise at 350 °F and handles 120 to 240 V circuits

  • Manual reset restores heat after safety trip
  • Opens at 350°F to stop overheating
  • SPST snap disc switches cleanly on temperature rise
  • Rated 10 A at 120 V and 15 A at 240 V
  • Compact 1 1/4 × 3/4 × 3/4 in fits tight HVAC spaces

Snap-disc limit rollout

The Value Brand 6UED1 is a snap-disc limit rollout switch that opens on temperature rise at 350 °F. It is a single-pole single-throw device with manual reset, intended for HVAC equipment that requires a fixed over-temperature cut-out.

Mounting and circuit role

The switch body measures 1 1/4 in high by 3/4 in wide by 3/4 in deep, allowing it to fit in tight control compartments. It interrupts 120 to 240 V circuits rated up to 15 A resistive or 10 A inductive, freeing the main controller from handling fault currents directly.

Thermal and electrical behaviour

Contacts open automatically when the sensing disc reaches 350 °F and remain open until the manual reset button is pressed. Under normal operation the device draws negligible power and produces no audible noise, acting as a passive thermal safeguard.

Questions about this item

At what temperature does the 350°F limit rollout open and cut power?

The snap-disc control opens on rise at 350°F, breaking the SPST circuit until the manual reset button is pressed.

How much heat does the switch itself add when it carries 10 A at 240 V all day?

At the rated 10 A / 240 V load the contact dissipation is minimal; the device is a passive thermal switch with no active cooling or heating elements.

What control voltage must the furnace supply for the 120–240 V coil circuit to operate?

The switch is rated for any AC voltage between 120 V and 240 V, so the existing furnace control circuit within that range will drive it directly.
