EN 50075:1990

Overview

EN 50075:1990 is a European CLC standard for flat non-rewirable two‑pole plugs, 2.5 A 250 V, with cord, intended for the connection of Class II (double‑insulated) household and similar equipment. It specifies the essential design and safety parameters for cord‑attached, two‑pole plugs without an earth contact, intended for indoor use where no special protection against ingress or water is required.

Key topics and requirements

• Rated values: designed for a rated current of 2.5 A and a rated voltage of 250 V a.c.
• Two‑pole, no earthing contact: suitable only for Class II (double‑insulated) equipment that does not require an earth connection.
• Non‑rewirable construction: plugs are supplied factory‑assembled with a cord and are not intended to be rewired by the user or installer.
• Indoor use and environmental limits: intended for indoor use with no special ingress protection; suitable for ambient temperatures normally not exceeding 25 °C, but may occasionally reach 35 °C.
• Scope of application: plug portions of adapters or equipment (e.g., razors, rechargeable lamps, plug‑in transformers) must comply with the standard’s requirements insofar as is reasonably applicable.
• Safety and compatibility: addresses form factor, insulation, mechanical strength and basic safety features appropriate for low‑power household appliances.

Practical applications

• Designed for small household appliances and personal care devices such as electric razors, shavers, battery chargers, small lamps and portable transformers that are double‑insulated.
• Used where a flat, low‑profile plug is preferred for compactness, travel adapters, or to reduce obstruction behind furniture.
• Ensures consistent safety, interchangeability and regulatory compliance for manufacturers, importers and retailers of corded Class II devices.

Who uses this standard

• Manufacturers and product designers of small household and personal devices.
• Compliance engineers and test laboratories verifying plug safety and conformity.
• Procurement and quality teams ensuring components meet European plug specifications.
• Retailers and importers selecting compliant, ready‑assembled plug‑cord assemblies.

Related standards

• Standards covering socket‑outlets, earthing plugs, cable/cord requirements and general appliance safety are typically referenced alongside EN 50075. For specific mating outlet types or earthing requirements, consult the applicable national and international standards.
