The ED250B-1 is a manually operated device with an over-centre spring mechanism which provides a snap action for both opening and closing of the main contacts. The ED250B-1 is easy to install (see drilling details in the datasheet of ED250 Emergency Disconnect), and is secured with supplied M5 posidrive mounting screws.

There are lockable versions of ED250 series, which feature 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.
