Johnson Controls Penn P28AA-41C

Oil failure control 55/500 kpa with 90 Sec time delay & manual reset

P28AA-41C provides dependable protection against major breakdowns on pressure lubricated refrigeration compressors by guarding against low lube oil pressure.

A built-in time delay switch, compensated for ambient temperature, allows for pressure pick up on start and avoids nuisance shut downs on pressure drops of short duration during the running cycle.

The time delay assembly (timer and terminal board) may be easily removed and replaced in the field. Time delay switch is a trip-free expansion rod device actuated by a resistance heater.
