Residual current protection device RCD320 Basic RCD type A mounted at the bottom Rated residual current 0.03...5A at 50/60Hz tv instantaneous 4-pole In=160A Ue=100-480V Accessories for: 3VA1 residual current measuring devices for molded case circuit breakers 3VA. Residual current protection devices can be used to prevent or reduce dangerous residual currents that cause damage to people, property and livestock. These are available as accessories for the 3VA series. All residual current protection devices detect both purely sinusoidal alternating residual currents and pulsating direct residual currents (type A). These accessories are characterized primarily by: 1. Available as type A (pulse current sensitive). 2. Simple mechanical attachment of the residual current measuring devices directly to the switch. This results in very compact dimensions. www.siemens.de/3VA.
