Danfoss KP6W pressure switch, 8-42 bar, double-bellows fail-safe, auto reset, SPDT, 1/4 in flare

Danfoss KP6W single (high) pressure switch, code 060-519066. Regulating range 8 to 42 bar, differential range 4-10 bar, automatic reset, SPDT snap-action contact. 1/4 in flare (male) connection, IP44 enclosure, ambient -25 to +65 °C, max working pressure (PS/MWP) and max test pressure 46.5 bar. The KP6 family uses a double bellows (an outer bellows plus a regulating bellows) as a fail-safe element: a leak in the regulating bellows is contained by the outer bellows so the switch fails to the safe (stop) position. Used for high-discharge-pressure protection of refrigeration and air-conditioning compressors.

Compatibility

Refrigeration/AC high-pressure (HP) protection with a fail-safe double-bellows element — distinct from the single-bellows KP5 (060-117166)/KP7B (060-513966). Higher 8-42 bar range and 46.5 bar max working pressure. Automatic reset; verify range and reset type before ordering.
