Supco Manual Reset Rollout Limit Switch F SPST

The Supco Manual Reset Rollout Limit Switch (SPST) is a bimetal rollout limit switch, also called a flame rollout switch or manual reset limit control. It is used in gas-fired furnaces, unit heaters and rooftop units. If excess heat rolls out of the burner area, the switch opens and shuts down the heating circuit. It stays open until someone resets it by hand. That makes it a dependable overheat safety device.

Key Features:

• Compact 1/2" bimetal temperature control design
• Manual reset: the switch must be reset by hand after it trips
• SPST (single pole, single throw) switch action
• Fixed cut-out temperature, opens on temperature rise
• 1/4" vertical quick-connect terminals
• UL recognized and CSA approved
• Uses 36T electrical ratings

The SRL series is a cost-effective universal replacement. It is designed to restore the original safety function of a tripped or failed rollout limit switch. Each variant in the line has its own fixed cut-out temperature, so choose the one that matches the original control.
