Allen Bradley Guardmaster Safety Enabling Switch, 3 Position, 2 NC - 440J-N21TNPM
Use this enabling switch from Rockwell Automation's Allen Bradley Guardmaster range to stay safe when adjusting hazardous machinery. It's commonly needed for tasks when a device is still running, such as observations and troubleshooting or calibration, tool changes and lubrication. The switch lets you safely adjust moving parts for emergency maintenance and repair. Operators can use the trigger switch by squeezing the handle to make fast emergency stops if a hazard occurs.
Features and Benefits
• Ergonomic surface design makes the switch comfortable to hold
• Pre-mounted base plate for extra stability
• Cable strain relief to protect from damage
• Dual three-position enabling switches for versatile use
Standards and Certifications
• IEC (International Electrotechnical Commission)
• EN (European Norm)
• NFPA (National Fire Protection Association)
• ANSI (American National Standards Institute)
• ISO (International Organization for Standardization)
How can I ensure the switch is safe to use?
IP66 Rated
IEC 60947-5-8:2006
With most machines, it's best to reduce speed or intensity before maintenance or repair begins. A reduced performance mode will give the operator more time to squeeze the trigger in the event of danger. The control system should be set up to ensure the machine remains in this mode for the entire time the operator is in contact.
