4 / 6 page Battery Isolation Switch E-1073-437 www.e-t-a.de 1646 4 2 For road vehicles, e.g. buses and coaches Series E-1073-1102-437... In this application, the E-T-A combined battery switch/circuit breaker has several functions: l High performance circuit breaker rated at 240 A, providing battery and cable protection from overloads and short circuits. l Isolation switch, for ON/OFF operation (e. g. for main system disconnection). l Remote control via external, low-current circuit. l Undervoltage protection from battery deep discharge should electrical loads be left on. l Early under voltage signalisation via a warning lamp (undervoltage status output), located as required. l Undervoltage operation can be overridden if required. l Auxiliary contact to disconnect the generator field. l Reverse polarity protection through immediate disconnection of the entire vehicle electrical system if the battery is incorrectly connected. These functions allow the number of components and cables required to be reduced, with significant space and weight saving benefits.

In this application, the E-T-A combined battery switch/circuit breaker has two functions: l High performance circuit breaker providing battery and cable protection from overloads and short circuits. l Isolation switch between battery and loads. In this application, an ON/OFF remote control switch can be provided in both the first and last carriages. This will enable all batteries to be disconnected from the power distribution system by the operation of one control, irrespective of its location. In the same way, all batteries can be re-connected by the operation of a single control switch. This is extremely helpful during coupling/de-coupling of carriages for example. In addition the E/A test input permits the operation of individual battery switch/circuit breakers during maintenance. This is a metric design and millimeter dimensions take precedence ( mm ) inch All dimensions without tolerances are for reference only. In the interest of improved design, performance and cost effectiveness the right to make changes in these specifications without notice is reserved.Product markings may not be exactly as the ordering codes. Errors and omissions excepted. |
