Robertshaw 6000-005 Vibra Switch

The Robertshaw 6000-005 Vibra Switch is a critical protection device engineered for industrial rotating and reciprocating machinery. Designed as a vibration detection switch, this SPDT NEMA 4 unit provides a reliable mechanical shutdown or alarm circuit when equipment exceeds preselected vibration setpoints. Operating on 117VAC/VDC, this Vibraswitch utilizes a magnetic latching mechanism that requires no power for operation, ensuring fail-safe monitoring of pumps, motors, and cooling towers. The 366-A8 factory model features a 0 to 4.5G range with continuous sensitivity adjustment, allowing for precise calibration against ambient harmonics. The weatherproof housing protects internal components in harsh outdoor environments, making it a standard for contractors maintaining HVACR refrigeration systems. By detecting mechanical imbalance early, this industrial vibration sensor prevents catastrophic shaft or bearing failure, offering a maintenance-free solution for permanent installations.

• Rugged Protection: Detects mechanical malfunctions such as broken blades or failing bearings across a frequency range up to 300 Hz.
• NEMA 4 Enclosure: Cast aluminum weatherproof housing ensures reliable operation in temperatures ranging from -40°F to 200°F.
• Versatile Compatibility: Rated for 7 Amps at 460V AC and 0.5 Amps at 120V DC for flexible integration into various control circuits.
• Precision Adjustment: Includes a calibrated setpoint dial for accurate G-force threshold settings with ±5% accuracy.
• Manual/Remote Reset: Equipped with a 117V AC reset coil to clear the latching mechanism after a vibration trip event.

How do I set the vibration trip sensitivity?
Adjustment involves rotating the setpoint screw to find the "zero point" while the machine is off, then backing off the screw to a level determined by the machine's normal operating vibration plus an overhead margin.

Can this be used in hazardous locations?
The 6000-005 is a standard NEMA 4 watertight model. For Class I or II hazardous environments, the explosion-proof 6000-10 series is required.

Does the unit require constant power to sense vibration?
No. The sensing mechanism is entirely mechanical; power is only required for the remote reset coil or to pass signals through the SPDT contacts.
