Product details

What it is and where it fits

The ABB S203M-D10 is a thermal-magnetic miniature circuit breaker (MCB) in the S200M series, rated for 10 A with a D tripping characteristic. It snaps onto standard DIN rail inside a distribution board or industrial control panel, protecting downstream wiring and loads against overcurrent and short circuits. The D-curve (10–20× In) is designed for loads with high inrush currents — motor starters, transformers, or lighting ballasts — where a B or C curve would nuisance-trip on startup.

Frequently asked questions

How do I get current pricing and availability for S203M-D10?

The S203M-D10 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate.

Will S203M-D10 drop into a panel that was specified around SH201T-C16 without rewiring?

No. The S203M-D10 is a three-pole breaker (3 modules wide on DIN rail) while the SH201T-C16 is single-pole (1 module wide). The footprint, wiring configuration, and current rating differ. A panel designed for single-pole SH201T breakers would need a different DIN rail layout and wiring to accept the three-pole S203M-D10.

What compliance documentation does this brand provide for S203M-D10?

ABB typically provides a Declaration of Conformity covering the S200M series for IEC/EN 60898-1 and IEC/EN 60947-2, along with RoHS and REACH compliance statements. Specific documentation for the S203M-D10 order code is available on request with the RFQ.
