210#CO 275#CI FAN CYCLE SWITCH

The SW-210xx Series Fan Cycle Switches (with a xxx in the model number) are designed to control and cycle various equipment. The switches are rated for 230/460VAC, 250 Amps, 60Hz or like voltage.

The SFC210275 HP and Fan Cycle Switches are typically used in heating, ventilation, air conditioning and refrigeration equipment. The switches consist of only a handle, knob and contacts designed to provide manual reset action or automatic reset action. These switches are intended for use in normally-open or normally-closed circuits.

The SFC210275 switch has a minimum pressure of 10# and a maximum pressure of 275#. It is a sealed, non-adjustable, manually operated switch that incorporates a safety trip lever. The HP/FAN cycle switch activates the gas valve to run a fan for circulation during refrigeration off-cycles to maintain the vacuum within the condensing unit.

These replace single motor HP pressure switches that run on a manual reset coil and a fan cycle switch. The top of the line switch is the type used in DOE vessels. The mounting flange of these switches is 1-1/8".

Sealed Unit Parts Company introduces the TCO cycle switch with an adjustable manual reset. The switch includes a manually operated lever actuated spring return pilot safety device that disconnects the gas supply to the burner in the event of excessive pressure in the system which can occur when a natural or LP tank is empty, or if the liquid line pressure drops suddenly causing liquid flow to stop.

The model SFC210275 pressure switch is designed for use with Supco air curtain units. The pressure switch comes with a 3-prong plug, EPDM seal and a duplex receptacle. This switch is ideal for controlling hood fans on the following units: SAW10, SCA10 and SSA10.

Manual reset condensate switches are designed to alarm at 210 pounds of boiler condensate and 275 pounds of ice condensate.
