Robertshaw 6000-009 Vibra Switch

The Robertshaw 6000-009 Vibra Switch is a critical malfunction detector engineered for continuous monitoring of rotating and reciprocating machinery. Designed to trigger a shutdown circuit before catastrophic failure occurs, this double pole double throw (DPDT) vibration switch identifies excessive imbalance or high-frequency vibrations caused by failing bearings or broken blades. It operates with a 117V AC/DC reset coil and features a broad, continuous adjustment range from 0 to 4.5G to accommodate various industrial loads. Built for durability, the unit is housed in a weather-resistant NEMA 4 aluminum enclosure, ensuring the protected sensitive vibration sensor mechanisms remain operational in harsh outdoor or wash-down environments. With a 300 Hz frequency response and ± 5% accuracy, this industrial safety switch offers precise protection for essential refrigeration compressors and motors. For systems plagued by humidity, the internal housing accommodates an optional heating resistor to prevent moisture condensation within the electrical compartment.

• DPDT Contact Configuration: Facilitates simultaneous control of shutdown circuits and remote alarm systems for enhanced site monitoring.
• Rugged NEMA 4 Protection: The heavy-duty housing provides a watertight seal against dust and rain, perfect for unsheltered industrial installations.
• Remote Reset Capability: Features a 117V AC electrical reset coil for clearing trips from a central control panel, reducing downtime.
• Adjustable Sensitivity: Linear adjustment from 0 to 4.5G allows for precise calibration regardless of the machinery’s baseline vibration.
• Broad Operating Temperature: Reliable performance in extreme conditions ranging from -40°F to 200°F.

What equipment is compatible with the Robertshaw 6000-009?
This switch is typically used on large industrial fans, centrifugal pumps, cooling towers, and reciprocating compressors where excessive vibration indicates mechanical failure.

How do I handle condensation inside the NEMA 4 enclosure?
In high-humidity environments, a 2-watt resistor should be wired across the internal terminals to maintain air circulation and prevent moisture buildup.

Can the 6000-009 be used in explosion-proof environments?
No, this model is rated for NEMA 4 weather resistance. For hazardous locations requiring Class I or Class II ratings, the 6000-10 series should be utilized instead.
