Overview
IEC 60884-2-1:2006 is the International Electrotechnical Commission (IEC) particular-requirements supplement to IEC 60884-1 for fused plugs used with household and similar socket-outlets. It applies where the fuse in the plug is primarily intended to protect the flexible cable or cord, not to protect the appliance itself against overload. This Part 2-1 is to be used together with IEC 60884-1 (general requirements for plugs and socket‑outlets).
Key topics and technical requirements
- Scope & intent: Fuses in plugs protect the cable/cord; they are not appliance overload protection. (Note: the standard mentions fused plugs are not used in DK.)
- Mandatory referencing: Used in conjunction with IEC 60884-1; references include IEC 60269-1 and IEC 60269-3 (low-voltage fuse series) and IEC 60417 (symbols).
- Fuse construction & placement:
- Replacement fuse elements must be accessible (replaceable) or permanently marked if non-removable.
- Fuse elements must be mounted between the cable conductor termination and the corresponding pin of the plug.
- The earth conductor must not be fitted with a fuse.
- For non‑polarized systems, all current-carrying poles (live and neutral) must be fused; for polarized systems, each phase pole must be fused.
- Marking and documentation:
- Plugs with fuses must be marked to indicate the presence of a fuse (symbol permitted).
- Detachable fused plugs must show the maximum rated fuse current; non‑detachable plugs must show the appropriate fuse rating for the attached cable/device as stated by the manufacturer.
- Safety and mechanical requirements:
- The fuse must not be removable or replaceable unless the plug is completely withdrawn from the socket.
- Contacts must maintain electrical connection with the fuse when the plug is assembled.
- Terminal heating limit: terminal temperature rise must not exceed 52 K (as an exception to Part 1).
- Testing & verification: Dimensional checks, insulation and dielectric tests, mechanical durability and other tests are primarily governed by IEC 60884-1 with the additions and modifications in this Part 2-1.
Applications and who uses this standard
- Manufacturers and designers of fused plugs and cord‑sets for household appliances.
- Product safety and compliance engineers preparing technical files for markets requiring IEC conformity.
- Test laboratories and conformity assessment bodies performing type and routine testing.
- Regulatory authorities, procurement teams and importers verifying safety labelling, marking and correct fuse ratings.
- Electrical installers and safety auditors referencing correct wiring and protection practices.
