ABB F200 RCCB, 25A, 4 Pole, 30mA, 400V ac / 1769635

F204 Type F, RCCB in four poles with rated current 25-40-63A and sensitivity 30mA for the protection of more than one single phase circuit with a single device.Type F features at a glance:Type F RCDs offer the same range of protection and functionality as an RCD Type A APR this means that they detect sinusoidal AC currents as well as pulsating DC currents. In addition to this, they are also tested according to IEC/EN 62423 which foresees the application of a simulated multi-frequency residual current with appropriate coefficient associated to the each level of frequency up to 1kHz. The intervention characteristic has a short-time delayed which prevents unwanted tripping in case pulsed leakage currents of up to ten milliseconds occur at activation of filters. The RCDs Type F have a surge current withstand capacity of more than 3kA and can accept superimposed smooth DC residual currents of up to 10mA without affecting their standard functionality.
