Detailed Description

Product Description AED250A 250A 80V Push Button for Battery Powered Vehicles 1NC AOKAI Emergency Switch  The AED250A range of switches have 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.  The AED250A 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 AED250A is easy to install (see drilling details) and is secured with supplied M5 posidrive mounting screws.  Lockable versions 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,Website:http://www.ak-contactor.com, 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. The AED250A is fully serviceable with genuine replacement parts available.  Precautions:  When fitted with magnetic blowouts the polarity marked on the contact housing must be observed when connecting the main terminals.  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.  Do not use as a regular On-Load Switching Device.Brand: AK/AOKAI Name: Emergency Switch Model: AED250A / ED250 Rated Voltage: ≤80V Rated Current: 250A Type:  Push Button Dimension: 64.5*63*132 (mm) Weight: About 450gSPECIFICATION      Rated Voltage≤80VContact Circuit Rated Load Current(A)250ATypical Voltage Drop Across Contacts per 100A≤60mVInsulation Resistance≥50MΩElectric Strength to Resist50Hz/60Hz 1000VAC/1minOverload Current≤7Ie, ≤1sElectric Life≥10000 timesMechanical Life50,000 timesWork SpecificationContinuousContact Form1NCContact MaterialAgCdO/AgCuOTechnical SpecificationGB14048.4-2010USAGE ENVIRONMENT      Altitudeless than 2KmAmbient temperature-25~+55℃International protectionIP50Installation typeIIIWay to installAnyVibration2.5g(5~50)HzImpact50g,11ms(Half-sine wave)SCHEMATIC DIAGRAMINSTALLATION DIAGRAMProduct Photo ShowHot Sale ProductsPackaging & ShippingCompany InformationProduct Application
