In order to fulfill the requirements for an adequate protection against earth faults ABB SACE has designed the following product categories: - Miniature circuit-breakers: • RCBOs(residual currentoperated circuit-breakers with integral overcurrent protection) DS201, DS202C series with rated current from 1 A up to 40 A; • RCBOs (residual current operated circuit-breakers with integral overcurrent protection) DS200 with rated cur-rent from 6A up to 63A; • RCBOs (residual current operated circuit-breakers with integral overcurrent protection) DS800 with 125A rated current; • RCD blocks(residual current blocks) DDA 200 type to be coupled with the thermal magnetic circuit-breakers type S200 with rated current from 0.5 A to 63 A; • RCD blocks (residual current blocks) DDA 60, DDA 70, DD 90 type to be coupled with the thermal magnetic circuit-breakers type S290 with rated current from 80 A to 100 A with C characteristic curve; • RCD blocks (residual current blocks) DDA 800 type to be coupled with the thermal magnetic circuit-breakers type S800N and S800S with rated current up to 100 A. These blocks are available in two sizes: 63 A and 100 A; • RCCBs (residual current circuit-breakers) F200 type, with rated current from 16 A to 125 A. • RD2-RD3: residual current monitor for fixing on DIN rail. - Tmax XT moulded case circuit breakers: • RC Sel 200mm XT1 (with adjustable time of non trip): residual current releases can be installed in 200mm modules; it can be coupled with X1 circuit breakers with a rated current up to 160A. • RC Sel XT1-XT3 (with adjustable time of non trip): residual current releases to be coupled with circuit breakers XT1, XT3 with a rated current up to 160A with XT1 and 250A with XT3
