The 060B017591 differential pressure switch belongs to the MP Differential Pressure Switches series manufactured by Danfoss for hydraulic automation duties that shut down equipment when suction pressure falls below a safe limit. A factory setting of 0.65 bar establishes the initial trip point, and the cut-out for falling pressure adjustment lets service staff fine-tune that threshold on site. A 0.2 bar contact differential defines the narrow window between open and closed states, while a single-pole double-throw contact offers change-over wiring flexibility. The contact rating of AC15 2 A 250 V or DC13 0.2 A 250 V caps the electrical load that may be switched. A relay release time of 60 s prevents rapid cycling, and a manual reset at minimum pressure ensures deliberate restarts after a trip. Process fluid connects through a G 3/8 male port conforming to ISO 228-1, and field wiring enters by a screwed Pg 13.5 cable gland specified in DIN 40430 for strain relief.
The device operates in ambient temperatures from –40 °C to 60 °C so it can be mounted in unheated machinery spaces. Its low-pressure side tolerates –1 bar vacuum up to 12 bar positive pressure, covering typical suction and return lines. Continuous duty is permitted up to 17 bar system pressure, and a 22 bar test rating allows periodic proof testing without damage. An IP20 enclosure rating limits installation to cabinets or sheltered panels where finger ingress is blocked but water protection is not required. These limits, together with the preceding switching characteristics, qualify the 060B017591 switch for reliable monitoring and control tasks in hydraulic circuits that depend on stable differential pressure.
