ABB ST202M-D16 Industrial Control Relay Module

ABB ST202M-D16 is a two-pole miniature circuit breaker (MCB) from ABB's S-series, configured as S202M-D16. It is rated for 16 A per pole at 400 VAC and employs a D-curve trip characteristic, suitable for circuits with moderate inrush currents. The device offers a short-circuit breaking capacity of 10 kA (Icn) and carries ABB’s catalog designation 2CDS272001R0161. With IP20 enclosure protection, the unit is designed to protect branch circuits within industrial control panels, including protections for control relays, contactors, sensors, and small automation loads. This MCB provides reliable overload and short-circuit protection while remaining compatible with ABB’s broader range of protective devices in the 2CDS/S202 family, helping ensure consistent coordination with other protection components in standard machine and process automation installations.
