 The Albright ED300B 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 use with battery-powered vehicles; they are also suitable for use with static power systems. All types are capable of safely rupturing full-load battery currents in the event of an emergency.

  • Rated: 300A, 12V, 24V, 48V, 72V and 96Vdc maximum.
  • Single-pole, single-throw (SPST).
  • Two M5 fixing screws at 48mm centres.
  • Two M8 hex bolts for battery cable fixing.
  • Suitable for voltages up to 96 Volts DC, commonly used on 12 Volts, 24 Volts, 48 Volts and 72 Volts DC electric vehicle systems.
For a lockable version, use ED300LB-3.

Magnetic Blowouts

 This unit is fitted with magnetic blowouts; the polarity marked on the contact housing must be observed when connecting the main terminals.

About The Albright ED300 Stop Switches

 The ED300B is a manually operated device with an over-center spring mechanism that provides a snap action for both the opening and closing of the main contacts. The ED300 is easy to install and is secured with supplied M5 Posidrive mounting screws.

 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 OEMs 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).
