Panel fit and rating
The 2CDS283103R0324: This ABB 4-pole miniature circuit breaker takes a standard DIN-rail footprint at 70 mm wide, with a 32 A C-curve thermal-magnetic trip and 15 kA short-circuit capacity at 440 V rated insulation voltage. C-curve trip suits general-purpose loads — motors, transformers, lighting banks — where moderate inrush occurs. Rated breaking capacity Icn and Icu both sit at 15 kA, so selectivity coordination with downstream breakers is straightforward at this level.
Mounting and termination
Mounts on DIN rail; IP20/IP40 enclosures accept the bi-directional cylinder lift terminals. Torque to 2.8 Nm on the screw terminals. Depth is 69 mm, which fits standard comb-busbar spacing and leaves clearance for door-mounted auxiliaries.
Production status and sourcing
This is an active product line. No last-time-buy notice is recorded — the part is specified into the BOM with standard lead times on an RFQ basis.
