Potter CF-135-MP — THERMOFLEX MP Series heat detector, fixed temperature only, 135°F (57°C), with factory-sealed pigtail leads.
In Potter's THERMOFLEX line, CF means fixed temperature only while CR adds a rate-of-rise element, and the MP suffix swaps screw terminals for fly leads sealed through a corrosion-resistant plate. That seal plate is why it goes into parking garages, loading docks and wash-down areas, where condensation or corrosive air attacks ordinary terminal wiring.
