Technical descriptionThe GW…A4 HP pressure switch is an adjustable pressure switch as per EN 1854 (GW 6000 A4 as per DIN 3398T3) for burners.It is suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the  specified  pressure  setpoint. The specified pressure setpoint (operating point) is set at a setting wheel using a scale.

Application Pressure monitoring in burner control systemsSuitable for gases of gas families 1,2,3 and other neutral gaseous media, as well as air, flue gases and combustion products

ApprovalsEC

type testing certificate as per: •  EC-Gas Appliances Regulation•  EC-Pressure Equipment Directive

Approvals in other important gas- consuming countries.

FunctionalPressure switch for applications involv- ing excess pressure.GW…A4 HPThe pressure counteracts the force of the setting spring on the micro-switch via the metal bellows. The pressure switch does not require power assist- ance.

Pressure switch GW…A4 HPThe switching mechanism reacts to overpressure and closes, opens or switches over a current circuit when the specified pressure setpoint is overshot or undershot
