SIST EN 61008-2-1:1996/A11:1999

Overview

EN 61008-2-1:1994/A11:1998 is a CLC (CENELEC) amendment clarifying the applicability of the general rules for residual current operated circuit-breakers without integral overcurrent protection (RCCBs) that are functionally independent of line voltage. The amendment (A11 / corrigendum issued March 1999) was adopted in several national bodies (e.g., SIST EN 61008-2-1:1996/A11:1999) and updates how the core requirements apply to RCCBs whose tripping function does not rely on the supply line voltage.

Key topics and technical scope

This standard and its amendment focus on application of the general rules to devices with independent tripping means. Key technical topics include:

• Applicability of the general EN 61008 series requirements to RCCBs that are electrically or functionally independent from line voltage.
• Clarification of construction and safety principles relevant to line-voltage-independent designs.
• Interpretation of performance and operational requirements for residual current detection and automatic disconnection of supply.
• Marking, documentation and user information needed for safe installation and maintenance.
• References to test and conformity assessment procedures as they apply to these specific RCCB types.

Note: The amendment deals with how existing general rules are to be interpreted for this class of RCCBs; it does not replace the general requirements but refines their applicability.

Practical applications and users

This standard is relevant to a range of stakeholders involved in electrical safety for domestic and similar installations:

• RCCB manufacturers and designers developing products whose tripping mechanism is independent of the mains supply.
• Electrical installers and contractors specifying and installing residual current protection in households, small commercial premises and similar environments.
• Testing and certification laboratories assessing conformity of RCCBs to CENELEC requirements (including amendments).
• Regulatory bodies and compliance officers referencing harmonized standards for product acceptance and national adoption (e.g., SIST adoption).
• Specifiers and procurement teams selecting RCCBs for projects where line-voltage independence is required for safety or functional reasons.

Related standards

• EN 61008 series (general rules for RCCBs)
• Other RCCB/RCBO standards and parts (for devices with integrated overcurrent protection or different functional architectures)
• National adoptions and corrigenda (e.g., SIST EN 61008-2-1:1996/A11:1999)
