Status‑Feedback Accessory for S200‑Series MCB: ABB S2C‑H6R Auxiliary Contact

Overview

The ABB S2C‑H6R (order code 2CDS200912R0001, part ID 10063361) is a right‑side‑mounted SPDT auxiliary contact accessory built for ABB S200‑family miniature circuit breakers, SN201, F200 and DS200‑series devicesABB Group. It mechanically couples to the MCB operating mechanism, outputting real‑time ON/OFF position feedback via one change‑over contact, independent of fault‑trip detection. This signal can be wired to PLC input channels, local panel indicator lamps or remote SCADA alarm systems to report breaker operational status without manual cabinet inspection.Only 8.8 mm slim width, this modular clip‑on accessory occupies minimal DIN‑rail space inside distribution panels. Widely used for industrial machinery panels, building management systems and critical‑utility power distribution, S2C‑H6R is a common spare for panel retrofits and field‑accessory replacement jobs. It is important to distinguish it from S2C‑S/H6R, which adds fault‑trip signal capability that S2C‑H6R does not possessABBSales.

Core Features & Technical Highlights

Full part number S2C‑H6R, ABB internal code 2CDS200912R0001; 1‑pole SPDT (CO) change‑over auxiliary contact, pure position‑feedback only, no trip‑alarm functionABB Group
Mounting rule: attaches exclusively to the right‑hand side of compatible MCB/RCCB/RCBO units; maximum two auxiliary accessories can be cascaded on one breakerABB Group
Contact rating: 240 V AC‑12 6 A; 30 V DC 3 A; purely signalling auxiliary circuit, not for main‑power load switching
Compact dimension: width 8.8 mm, height 85 mm, depth 69 mm; weight 43 g; DIN‑rail‑compatible modular accessory, no separate rail‑clip requiredABB Group
Mechanical linkage strictly follows MCB main‑contact mechanical position; status changes synchronously with manual ON/OFF operation as well as overload‑caused tripping
Compliance with IEC 60947‑5‑1, UL 1077 and CSA 22.2 standards; operating ambient‑temperature range‑25 °C to +60 °CABB Group
Not interchangeable with S2C‑S/H6R (combined position + fault‑alarm version); cannot be installed on the left‑side of circuit breakers.

Typical Application Scenarios

S2C‑H6R auxiliary contacts are deployed where remote breaker‑position monitoring is required. Typical use‑cases include machine‑tool control‑panel feedback loops, water‑treatment plant power‑circuit status acquisition, building‑automation BMS signal collection, MCC branch‑circuit monitoring and OEM equipment remote‑diagnosis systems.When integrated with PLC or SCADA systems, operators can view MCB status from control rooms instead of physically visiting distribution cabinets. Mechanical wear or incorrect installation may cause loss of position‑signal tracking, leading to mismatched remote display vs real‑breaker state. Maintenance teams stock genuine S2C‑H6R spare units for fast clip‑on replacement to restore status‑feedback function.

Compatibility & Field Maintenance Guidance

During spare‑part procurement, confirm full catalog number S2C‑H6R. Do not mix‑up with S2C‑S/H6R; the latter supports separate fault‑trip signalling and has different internal logicABBSales. Verify compatibility with target breaker models: S200, S200P, SN201, F200, DS200‑series are supported. Other‑series breakers are not mechanically compatible.Installation must follow ABB official accessory installation instructions, performed by qualified electrical technicians. After clipping the unit onto the right‑side of MCB, technicians must manually toggle the MCB ON/OFF multiple times to validate synchronous auxiliary‑contact switching. Preventive maintenance includes visual inspection of mechanical coupling and terminal‑screw tightening during regular panel‑inspection cycles.Only genuine ABB S2C‑H6R guarantees precise mechanical linkage and rated auxiliary‑contact capacity. Aftermarket counterfeit accessories risk out‑of‑sync signal feedback, contact‑burn‑out and false status reports to upper‑level monitoring systems.

Summary

The ABB S2C‑H6R auxiliary‑contact module delivers reliable mechanical‑coupled position‑feedback for S200‑series MCB and compatible residual‑current devices. It is a practical low‑cost accessory for implementing remote‑status‑monitoring within industrial and building‑automation power‑distribution systems. Correct part‑selection, right‑side installation and post‑assembly functional test are essential to guarantee accurate signal transmission.Tags: ABB S2C‑H6R, 2CDS200912R0001, MCB auxiliary contact, S200‑series breaker accessory, SPDT position‑signal contact, low‑voltage modular spare part
