Anti Restarts

Anti-Restarts

The inexpensive solution to OSHA

Anti-automatic restart (undervoltage) protection without the high cost of magnetic motor starters

The following standards apply to machines driven by 120 and 240 volt fractional horsepower motors:

OSHA

(U.S. Occupational Safety and Health Administration #1910.213 (b) (3)*

NFPA 70

(National Electrical Code, 1990 Edition #430-43**)

 “On applications where injury to the operator might result if motors were to restart after a power failure, provisions shall be made to prevent machines from automatically restarting upon restoration of power”.  “.. A motor that can restart automatically after shutdown shall not be installed if its automatic restarting can result in injury to persons.”

The Safe-Start Plug:

  • Updgrades small machines to the latest safety requirements by preventing automatic restart accidents, after a power interruption.
  • Simply replaces the old power cord on machines, and plugs into standard duplex outlet.
  • Permits the use of machine “on-off” switch, a before.
  • Complies to the latest O.S.H.A., N.E.C. and N.F.P.A. safety standards.
  • Replaces old, frayed, dangerous, “Ungrounded” power cords.
  • Offers electrical disconnect compliance by unpluggin.

Operating Characteristics

With the Safe-Start Plug or the Safe-Start, correctly installed on existing equipment it will provide protection against unexpected start-up and motion and motor burn-out in the following manner:

Voltage Drop or Power Interruption Protection: In the event the equipment while being operated (motor switch in “On” position) should stop due to loss or drop of electrical power due to power failure from any cause, the Safe-Start will automatically disconnect and shut off power to the equipment so that upon restoration of power the equipment will not start up even through the motor switch is in the “On”  position. In order to restore power to the equipment the switch must be turned “Off” first and the reset button depressed on the Safe-Start. In the event the equipment is inadvertently unplugged and then plugged back into the receptacle while the motor switch is in an “On” position, the equipment will not restart until the reset button on the Safe-Start is depressed.

Scope of Application

The Safe-Start is intended for installation on equipment which is driven by a small electrical motor, operating on 120 V.A.C. or 240 V.A.C. (single phase) and which is connected to the source of electrical power by means of a 3-wire flexible cord.

Which Safe-Start Model Should You Use on Your Machine?

Use Model #50-15 on 120 volt machines where the power cord is old and/or you want the reset button up closer to to the machine for easy access.

Purchase Model #50-15

Use Model #50-18 on 120 volt machines where the power cord is old and/or you want to connect to a disconnect box or you want to install a 20 amp plug on the cord or a twisting locking type plug on the cord.

Purchase Model #50-18

Use Model #50-25 on 120 volt machines where the power cord is old and/or you want the reset button up closer to the machine for easy access.

Purchase Model #50-25

Use Model #50-35 on all 200 to 240 volt single phase (3 wire) machines.  You must install any matching plugs on the power cord.

Purchase Model #50-35
