An easy safety upgrade.
These anti-restart motor starters are great for drill presses, bench grinders and various other small 120 volt machines. Motor starters prevent the machine from starting up on it’s own. It also adds a nice big emergency stop button that can be hit if needed.
We can also add upgrades such as a key to prevent unauthorized use, and a LOTO (lock out, tag out) device. If you’re not sure if this thing is right for your machine, Give us a call – we are a very friendly bunch of people and would love to help you out.
Why do you need a motor starter box?
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. A magnetic starter is basically what is inside our anti-restart motor starters.
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. When the power comes back on, the machine turns on automatically! Not only is this dangerous, but completely avoidable.
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.
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.
