Ashcroft Switch APS N7 1H 012C S 02 30# – 15 R – X6B

• Function : Pressure switch, single setpoint, fixed deadband, field adjustable (APS)
• Enclosure : Explosion Proof 316 SS body (N4)
• Microswitch : Single switch – SPDT, Higher Current – 5A @ 125/250 Vac, 5A @ 28 Vdc resistive, 3A @ 28 Vdc inductive. (1H)
• Electrical Connection: ½ NPT male conduit connection with 18 AWG wires. 12˝ lead wires. Specify wire length in inches. (012C)
• Actuator Seal : 316 SS welded Diaphragm, ranges ≤200 psi (S)
• Pressure Connection : 1⁄4 NPT Male (02)
• Switch Range : 30 psi (30#)
• Setpoint: 5 characters maximum representing setpoint of the switch in the same units as the range of the switch. For setpoints in Vacuum specify as “– ”pressure. If no setpoint is required on an APA switch use either “NSR” or “NSD.” If direction is not known use “NSR” as the default. (15)
• Setpoint Direction: Rising Pressure (Increasing pressure, decreasing vacuum) (R)
• Options: Cleaned for oxygen service (X6B)
