4294A

4294 Hazardous Area Vibration Switch

Function: Armature mechanism trips on high vibration and activates snap action switch(es)
Amplitude range: 2 - 10 g
Frequency range: 0 to 3600 RPM
Reset: Local reset plus optional remote reset electrical coil.
Start delay: Applying reset coil voltage at startup holds mechamism from tripping for 20 to 30 seconds, after which the switch is automatically activated. Requires electric reset option.
Temperature range: -40 to 70°C -40 to 158°F
Enclosure: Cast aluminum
Switch contact(s) rating:

15 amps, 125 or 480 VAC

1/2 amp, 125 VDC

1/4 amp, 250 VDA

1/8 hp, 125 VAC

1/4 hp, 250 VAC

Hazard rating: UL, ATEX, depending on model ordered

See datasheet for complete specification.
