SIEMENS Q22030CT 30A Double Pole + Two 20A Single-Pole Triplex Circuit Breaker

Overview

The SIEMENS Q22030CT is a compact plug‑in triplex circuit breaker designed for compatible Siemens load centers. It consolidates one 30A double-pole unit with two 20A single-pole units in a single 1/2‑inch frame, offering additional circuit capacity without expanding the panel footprint. The modular design is tailored for panels that need new circuits but lack spare spaces, helping you streamline installations in tight electrical closets or main distribution panels.

Key Benefits

• Space-saving 1/2‑inch frame fits in crowded panels, helping reduce clutter.
• Plug-in type enables quick upgrades with minimal wiring work.
• UL listed, providing a standard of safety and compatibility in supported load centers.
• Triplex configuration combines a 30A double‑pole with two 20A singles for flexible circuit expansion.

Compatibility and Installation

From the manufacturer, these breakers are intended for use in Siemens EQ, Ultimate, ITE, and Gould load centers rated to accept type QT breakers. Always check the wiring diagram to confirm compatibility. To keep a Siemens panel warranty intact, use only Siemens breakers as specified by the panel manufacturer.

Real‑World Scenarios

• Adding new lighting or receptacle circuits in a panel that has limited available spaces.
• Expanding a residential or light commercial distribution by consolidating two singles and a double‑pole into a triplex unit.

Note: Siemens cautions against the use of used breakers. The installation of used breakers in a Siemens panel can void the panel warranty, and Siemens does not sell used breakers or approve third‑party sellers.
