Описание (английский):

IEC 60898-3:2019 applies to DC circuit-breakers, having a rated DC voltage not exceeding 440 V, a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 10 000 A. These circuit-breakers are intended for the protection against overcurrents of wiring installations of buildings and similar applications; they are designed for use by uninstructed people and for not being maintained.

Overview

IEC 60898-3:2019 specifies requirements for DC circuit-breakers intended for overcurrent protection in household and similar wiring installations. The standard covers circuit‑breakers for DC operation with a rated DC voltage ≤ 440 V, rated current ≤ 125 A and rated short‑circuit capacity ≤ 10 000 A. These devices are designed for use by uninstructed people and for installations that are not intended to be maintained.

Key topics and technical requirements

Scope and classification – Definitions, device types, number of poles and current direction through poles for DC operation.

Rated quantities – Rated DC voltage, rated current and rated short‑circuit capacity within the values above.

Construction and safety – Mechanical design, protection against electric shock, clearances and creepage distances for insulation coordination.

Performance characteristics – Tripping characteristics (time‑current and instantaneous), behaviour at small DC currents and making (inrush) currents, temperature rise and continuous duty.

Terminals and connections – Requirements for screws, current‑carrying parts, terminal reliability and non‑interchangeability.

Marking and information – Mandatory marking and product information for safe installation and use by non‑specialists.

Testing and verification – Extensive type tests including dielectric strength, insulation resistance, humidity resistance, temperature rise, mechanical and electrical endurance, short‑circuit performance and verification of tripping characteristics.

Annexes – Normative annexes include methods for determining clearances/creepage and test sequences/sample requirements.

Applications and who uses this standard

IEC 60898-3:2019 is used by:

Manufacturers developing DC circuit-breakers for residential and similar installations.

Test and certification laboratories performing type and routine testing to verify compliance.

Electrical specifiers and designers selecting overcurrent protection for building DC circuits (e.g., small DC distribution, battery and PV subsystem protection in dwellings).

Regulatory bodies and procurement teams creating product requirements and compliance criteria for household electrical safety.

Installers and inspection authorities relying on standard marking and information to ensure safe, non‑specialist use.
