Q3030 - Siemens 30/30 Amp Tandem Single Pole Type QT Plug-In Circuit Breaker, 120/240VAC, 10kA Interrupt, Thermal Magnetic Trip, Q Series

Product Overview

The Siemens Q3030 is a tandem (dual) single-pole Type QT plug-in circuit breaker rated 30/30 amps for use on 120/240 VAC panelboards. It features a thermal-magnetic trip mechanism and a 10 kA interrupting rating.

This Q Series breaker installs in compatible Siemens/compatible Type QT panelboards to provide two independent 120V circuits in a single breaker space (tandem configuration).

Key Features

• Tandem single-pole (Type QT) — two 30A circuits in one breaker footprint
• Thermal-magnetic trip for overcurrent protection
• Rated for 120/240 VAC service
• 10 kA interrupting rating (10,000 A)
• Plug-in mounting for Q Series/Type QT compatible panels

What this breaker does

The Q3030 provides overcurrent protection for two separate 120 V circuits using a tandem single-pole configuration. Each pole is rated at 30 amps and the device uses a thermal-magnetic trip mechanism to respond to overloads and short circuits.

• Two independent 30A single-pole circuits in one breaker unit (tandem).
• Thermal element protects against overload; magnetic element responds to short-circuit fault currents.

Electrical ratings and performance

Use the Q3030 where the electrical system requires 120/240 VAC service and 30-amp branch circuits. The breaker has a 10 kA interrupting rating.

• Voltage: 120/240 VAC
• Ampacity: 30/30 A (tandem single-pole)
• Interrupting rating: 10,000 A (10 kA)
• Trip type: Thermal-magnetic

Panel compatibility and form

The Q3030 is a Type QT plug-in tandem breaker intended for use in Siemens Q Series or other panels that accept Type QT tandem breakers. Ensure the panelboard documentation allows tandem/half-size breakers in the desired circuit positions before specifying.

• Form: Plug-in tandem (dual single-pole) Type QT
• Intended for Q Series/Type QT compatible panelboards

Mounting and installation type

This breaker installs via a plug-in mechanism into the panelboard bus. Follow the panel manufacturer's installation instructions and applicable electrical codes when installing or replacing breakers.

• Mounting: Plug-in
• Installation: Requires compatible Q Series/Type QT breaker spaces and compliance with local electrical code
