To prevent differential currents retina on people, animals and objects, useful to avoid or you can reduce differential current protection. These are available as an accessory for the 3VA series. All differential current protection devices to detect both pure sine wave alternating fault and one-way pulsing currents (type A). These components are mainly distinguished by: 1. Available as type A (pulse current sensitive). Second Simple mechanical recessed of the difference of current measuring devices directly on the switch. Thus very compact dimensions. www.Siemens.de/3VA.
