ABB 2CSB203701R3630 RCCB 63 A 0.03 A

The FI block (RCU) is for customer-facing installation with circuit breakers of the S200 series. The following FI/LS combinations (RCBOs) provide personal and property protection as well as protection against electrically ignited fires according to DIN VDE 0100-410 and DIN VDE 0100-530. They protect 1P+N, 2P, 3P, 3P+N or 4P circuits against overload and short circuit currents, protection against sinusoidal AC and pulsating currents with a smooth DC fault current up to 6 mA against earth. Fault protection (protection in case of indirect contact), additional protection (with IΔn ≤ 30 mA) and fire protection (with I∆n ≤ 300 mA). They comply with the product standard IEC/EN 61009 Annex G. Areas of application are industrial and industrial applications. The FI block DDA200 AE is supplied with two additional terminals, which are used in emergency stop circuits for remote opening in positive safety. A remote control circuit should be connected to these clamps when buttons with NC contacts are switched in series.
Note that no more than one DDA200 AE can monitor the same circuit and a permanently assigned EMERGENCY STOP circuit is required for each DDA200 AE. The DDA200 AE must be supplied from above. When mounted to the S200 P circuit breakers, separation properties are provided in accordance with IEC 60947-1-1.
