Q23020CT2 - Siemens Quadplex Circuit Breaker, 2-Pole, 30A-20A, 120/240V, Plug-In, 10kA Interrupt, Thermal Magnetic Trip, UL Listed, CSA Certified, SWD & HACR Rated

Product Overview

The Q23020CT2 is a Siemens quadplex plug‑in circuit breaker configured as a 2‑pole device with 30A and 20A poles for 120/240V systems. It uses a thermal‑magnetic trip mechanism and carries UL listing and CSA certification.

Designed for use in compatible Siemens load centers and panels, the breaker has a 10 kA interrupting rating and is rated SWD (switching duty) and HACR (heating, air‑conditioning, refrigeration) where those ratings apply.

Key Features

• Siemens part number Q23020CT2 — quadplex form factor, plug‑in style
• 2‑pole configuration with one 30A pole and one 20A pole for 120/240V circuits
• Thermal‑magnetic trip provides combined long‑time and short‑circuit protection
• 10 kA interrupting rating
• UL listed and CSA certified; SWD and HACR rated

Function and protection type

The Q23020CT2 uses a thermal‑magnetic trip mechanism that combines overload protection (thermal) with instantaneous trip for short‑circuit events (magnetic). It is configured as a quadplex-style plug‑in breaker arranged to provide 2‑pole service with uneven pole amperages (30A and 20A).

• Thermal element: protects against sustained overloads
• Magnetic element: provides rapid response to high fault currents
• Plug‑in mounting for use in compatible Siemens breaker panels

Electrical ratings and interrupting capacity

This SKU is specified for 120/240V systems and includes two poles rated 30A and 20A respectively. The breaker has a 10 kA interrupting rating, which describes its capacity to safely interrupt fault current up to 10,000 amps under specified conditions.

• Voltage: 120/240V
• Pole configuration: 2‑pole (one 30A pole, one 20A pole)
• Interrupting rating: 10 kA

Panel and application compatibility

The Q23020CT2 is a plug‑in quadplex breaker intended for use in appropriate Siemens load centers and distribution panels designed to accept quadplex/plug‑in breakers. Confirm panel model and bus compatibility before installation.

• Plug‑in quadplex style — fits compatible Siemens panels
• Intended applications include branch circuit protection where mixed amperage poles are required

Certifications and special ratings

This breaker carries UL listing and CSA certification and is rated SWD and HACR where those ratings are applicable. These certifications indicate conformity with recognized safety and performance standards for circuit breakers.

• UL listed
• CSA certified
• SWD (switching duty) rated
• HACR (heating, air‑conditioning, refrigeration) rated

Before You Order

Confirm the model number and required quantity before ordering. Verify panel compatibility, bus type, and available space for a quadplex plug‑in breaker in your Siemens load center or distribution panel.

• Confirm the panel accepts quadplex plug‑in breakers and the Q23020CT2 shape/form
• Verify the mixed amperage (30A and 20A) pole configuration meets the intended circuit protection needs
• Have an electrician confirm that the 10 kA interrupting rating is appropriate for your service fault‑current level
