250 VDC Magnet Safety Disconnect Switch

 

Safety Disconnect SwitchProductivity and operator safety remain key concerns of all Ohio's customers. That's why we pair our performance-engineered solutions with well-designed safety equipment. At times, operators of heavy equipment need to disconnect the magnet while the equipment is still energized. Standard knife or safety switches are not capable of breaking this highly inductive magnet energy. Ohio's magnet disconnect switch interrupts the magnet circuit arc by using a quick break switch with a permanently connected power diode across negative and positive of the switch output. The power diode directs the discharge current from negative to positive while blocking the normal current from positive to negative.  The power resistor dissipates the stored energy of the inductive magnet circuit (30 A and 60 A switches do not require a power resistor.).  The switch is polarity sensitive.
