South Western Railway RCBO ISI Marked IS 12640 Part 2 Tender 2026

Tender Overview

The South Western Railway (Indian Railways) is seeking the supply of Residual Current Operated Circuit Breakers (RCBO) with Integral Overcurrent Protection, ISI Marked to IS 12640 (Part 2). The procurement focuses on single or multiple RCBO units meeting IS 12640 Part 2 standards, with BIS certification and OEM authorizations mandated. The scope is limited to the supply of goods; on-time delivery and post-sale service infrastructure are implied through service-center requirements. The tender emphasizes GST-compliant invoicing via GeM and a 30-day establishment window for a functional service center if not already present. Unique clauses include proof of BIS certification, OEM authorization, and specific field-activation documentation.

Key differentiators include mandatory BIS/ISI compliance, on-site or carry-in warranty considerations, and the requirement to demonstrate capability via performance documentation such as CRAC/CRN/RI TES inspection certificates. This tender targets suppliers with established service networks and BIS-verified RCBO products, aligning with Indian Railways safety standards and supply-chain reliability in government procurement.
