Robertshaw Vibration Switch 375A-A1-D0, 0-4.5 G, NEMA 4 Housing, Start Delay 30 seconds

The Robertshaw 375A-A1-D0 Vibraswitch malfunction detectors provide maximum protection for large motors, pumps, compressors and other rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur. Robertshaw "Start Delay Only" models hold the Vibraswitch armature in its "reset" position for a preset starting time after application of supply voltage to the instrument. This prevents the Vibraswitch from tripping out during machine startup. Fixed timing periods of 15, 30, 60 or 90 seconds are available. After the time period, the Vibraswitch functions as normal with shutdown or alarm functions provided by utilizing the SPDT switch contacts in the unit.

The 375AA1D0 vibration switch has a range of 0-4.5 G's. Contacts are SPDT 5A for the Start Delay models and SPST 2 A Triac Solid State Contacts (NO or NC operation) for the Monitor or Start & Monitor Delay Models. The Robertshaw 375AA1D0 is NEMA 4, NEMA 12 and CSA enclosure 4 and 12.
