Scheme X Certification Process for Low – Voltage switchgear and controlgear
.jpg)
Low-Voltage (LV) switchgear and controlgear are guaranteed to follow Indian Standard (IS) norms for safety, performance, and dependability by means of Bureau of Indian Standards (BIS) Scheme X certification. Manufacturers must get this certification if they wish to sell their goods in India; IS/IEC 60947 and IS 13947 guidelines control this certification.
Manufacturers under Scheme X have to show conformity by following rigorous quality control and in-house testing protocols. Applying, doing product testing at BIS-approved labs, and completing a factory inspection to confirm production methods comprise the certification procedure. Key LV switchgear and controlgear components needing certification are circuit breakers, contactors, relays, switchboards, motor control centers (MCCs), and busbars.
Products falling under the Compulsory Registration Scheme (CRS) or ISI Mark Certification must be kept in conformity by regular audits and market surveillance. Manufacturers accredited can use the ISI Mark or BIS Certification Mark, therefore guaranteeing product dependability and regulatory compliance.
Ensuring electrical safety, reducing dangers, and standardizing LV switchgear devices in India's power distribution and industrial sectors depend on this certification. Manufacturers have to keep strict quality control procedures if they want to keep their BIS Scheme X certification.
