Table

PoE Standards, Types, Classes, and Watts

PoE Standards, Types, Classes, and Watts lookup table with assumptions and boundary notes.

Scope

Low-voltage power planning only. It does not design a data cabling system or approve device compatibility.

Lookup table

Compare common Power over Ethernet type and class labels by approximate power levels.

Scroll sideways to keep row labels aligned with hidden columns.

Lookup basis uses rounded IEEE 802.3 PoE type and class power relationships.

Type 2PoE+4up to about 25 W
Type 3PoE++5 to 6up to about 51 W

Notes
  • Check table values for preliminary lookup and arithmetic checks only.
  • Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
