Overview

The Siemens Q22030CT is a Type QT triplex thermal-magnetic circuit breaker that combines two independent 20 A single-pole circuits with one 30 A two-pole common-trip circuit. Its 20-30-30-20 handle arrangement provides this exact circuit combination in two load-center spaces for compatible Siemens 120/240 V AC panels.

Key Features

  • Protection: Thermal-magnetic elements protect against sustained overloads and short circuits; the two inner 30 A poles operate as a common-trip pair.
  • Space-saving configuration: Two 20 A one-pole circuits and one 30 A two-pole circuit are integrated into one Type QT triplex assembly.
  • Compatibility: Intended only for Siemens load centers specifically labeled for Type QT breakers and for panel positions that permit this triplex arrangement.
  • Performance: Rated 120/240 V AC with a 10 kA interrupting rating for listed residential branch-circuit applications.

Specifications

  • Manufacturer / model: Siemens Q22030CT, Type QT
  • Circuit arrangement: Two 20 A, 1-pole circuits plus one 30 A, 2-pole common-trip circuit
  • Voltage / phase: 120/240 V AC, single phase
  • Interrupting rating: 10 kA
  • Mounting: Plug-in; requires a Siemens panel position approved for Type QT
