SD200AB-16 Albright 24V Emergency Stop Switch with Auxiliary - Intermittent

 Albright heavy-duty 24Vdc emergency battery disconnect switch with auxiliary and magnetic blowouts.

• Rated 200A, 24Vdc intermittent coil.
• Single pole.
• Internal fixing screws at 48mm centres.
• Two M8 hex bolts for battery cable fixing.
• Enclosed top cover is fitted.

Magnetic Blowouts

 These contactor switches are fitted with magnetic blowouts (denoted by 'B' suffix in the SD200B range) across contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the cover of the contactor must be observed.

About The Albright SD200 Emergency Stop Switch

 The SD200 combines the dual function of a manual disconnect and coil operated line contactor. The benefits of this design include compact size and reduced installation costs combined with an electrical capacity sufficient for most small and medium-size electric vehicles.

 The SD200 has been designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults.

 The operation of the switch is such that with the operating knob depressed i.e. in the “off” position, no electrical functions can take place. However, if the knob is in the “On” position, the option of energising the coil and thus closing the main contacts becomes available. The coil energisation can be carried out either through the vehicle keyswitch or as a result of a signal from the vehicle electronic controller. When used as an emergency battery disconnect switch, manually depressing the operating knob will override the energised coil such that the main contact and the auxiliary contact (where fitted) will open until such time as the knob is again moved to the “on” position.

 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.
