Residual current circuit breakers (RCBOs) provide protection for people and property, as well as protection against electrically ignited fires in accordance with DIN0100-410 and DIN0100-530. They ensure protection of single-phase circuits against overload and short-circuit currents, protection against sinusoidal alternating currents and pulsating currents with a smooth DC residual current component of up to 6 mA to earth. As well as fault protection (protection against indirect contact), additional protection (with I n 30 mA) and fire protection (with I n 300 mA). They meet the product standards IEC/EN 61009-1, IEC/EN 61009-2-1., The provisions according to DIN EN 45545 (fire and smoke protection standard) R22-R26 and Category 1 - Class A and Class B according to IEC 61373 (shock and vibration resistance) make the DS201 AT suitable for use in rail vehicles., The extensive range of accessories offers you everything you need for your installation tasks., The approvals are: CCC (China), EAC (Russia), RCM (Australia)., Optimal compromise between safety and operational continuity thanks to the interference immunity with surge current resistance (surge current form 8/20 s) = 3,000 A against unwanted triggering and 10 ms short-time delay., Rated switching capacity according to IEC/EN 61009 Icn = 6 kA., RCBO DS201 AT (Traction) Type A is 1-pole protected (LS), 2-pole switching.
