Motor starter boxes

Motor starter boxes


Why do you need a motor starter box?

  1. A motor starter prevents machine and motors from starting back up after a power failure.
    OSHA does recognize NFPA 79:7.5.3 that states, to prevent accidental or unintentional restarting of a machine requires all machines to have a magnetic starter. On machines such as drill presses and grinders that use mechanical power switches like those of a light switch, the power connection is always maintained until a person physically pushes a button or flips a switch. If a power failure happens, the machine will turn off because it has no electricity from the outlet. The danger happens when the power comes back on and the machine turns on automatically. Motor starters prevent the machine from starting up by automatically resetting the circuitry and unloading the motor from the power source. A button must be pressed in order for the motor starter to engage and start the machine and its motors.

  2. It prevents restarts after an interlocked guard is closed.
    Without a motor starter, interlocked safety guards would stop the machine if opened and would also start the machine up immediately after the guard was closed. Not only is it very dangerous to wire a machine this way, it is also a dangerous misuse of the interlock switches. Limit switches and interlock switches were never designed or intended to control motor current loads.

  3. It prevents damage to equipment.
    Our motor starter boxes have built in thermal overload relays for protection. If ever the motor stalls due to a very heavy cut or because of mechanical or electrical failure a protection device inside the starter box immediately turns off the system. A manual reset must then be performed after the cause of the problem is diagnosed and detected.
