About The Albright ED250 Stop Switches
The ED250 is a manually operated device with an over-centre spring mechanism that provides a snap action for both the opening and closing of the main contacts. The ED250 is easy to install (see drilling details) and is secured with supplied M5 Posidrive mounting screws.
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.
| Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
