About The Albright ED300L-3 Stop Switches
The ED300L is a manually operated device with an over-center spring mechanism which provides a snap action for both opening and closing of the main contacts. The ED300 is easy to install and is secured with supplied M5 Posidrive mounting screws.
This lockable version features a key which is necessary for the knob to be moved from the “Off” position to the “On” position. Once in the “On” position, the key can be removed. Thereafter, the knob may be depressed to the “Off” position where it will automatically lock and remain locked until the key is used again to unlock it.
Ensure that the switches are installed in a position where heavy arcs emanating from the switch cannot damage or electrically jump across to adjacent parts. The switch is to be used to rupture current in an emergency or as a no-load isolator.
A typical comment regarding its big red button appearance is that it is obnoxious, a very apt description, when you need to kill a circuit in an emergency you need the button to be obvious and obnoxious, many OEM's would agree, and will fit the Albright emergency switchgear as standard equipment.
