About The ED252 Emergency Stop Switch
The Albright emergency stop switchgear is a world leader in the electric vehicle market due to its hardwearing and ease of inspection configuration.
The ED252 range of switches has been designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults. Whilst the switches are primarily intended for battery-powered vehicles; they are also suitable for static power systems. All types are capable of safely rupturing full-load battery currents in the event of an emergency.
The ED252 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 ED252 is easy to install (see drilling details) and is secured with supplied M5 Posidrive mounting screws.
|Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance).
