Machine Tool Guards and Shields
Anti-Restart Control Box
Emergency Stop and anti-restart protection
An anti-restart device prevents machines from automatically restarting after a power interruption or outage. The Anti-Restart Control Box places the machine's motor circuit behind a latching starter and a dedicated emergency stop, so power returning to the building does not return power to the spindle and the operator must deliberately restart the machine. It is intended for older equipment that still runs on a mechanical on/off switch with no restart protection and no emergency stop.
Key Features
- Prevents automatic motor restart after a power interruption, brownout, or restored outage
- Dedicated emergency stop function added to machines that were built without one
- Magnetic starter with latching control circuit that drops out on loss of voltage and will not re-energize on its own
- Operator controls are separated from the power panel and mounted at the point of use
- Retrofit solution for legacy machine tools: no replacement of the machine's existing motor required
- Supplied as a complete controlled-restart package when paired with the required control station

Assembly
- Enclosed 3-phase starter panel with magnetic motor starter and anti-restart control circuit
- Panel electrical schematic for field verification and wiring
- Line-side and load-side wiring, conduit, disconnect, and overcurrent protection are supplied by the installer and sized to the machine and local code.
Common Uses
- Manual milling machines with mechanical drum or toggle switches
- Engine lathes and turret lathes without restart protection
- Drill presses, radial arm drills, and other legacy 3-phase machine tools
- Machines identified in a risk assessment or audit as lacking an emergency stop
