Product Overview
The Siemens Q3015 duplex type QT circuit breaker is designed for use in Siemens panels that accommodate CTL type QT breakers. This compact unit combines a 30 Amp and a 15 Amp single pole breaker within a single 1-inch housing, offering efficient space utilization in electrical panels.
It provides ground fault equipment protection with a 30mA trip, and is rated for 10 KAIC at 120V. Its plug-in mount design facilitates straightforward installation.

Important Safety Information
WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Always consult with a qualified electrician for installation and maintenance of electrical components.
- Always disconnect power at the main service panel before working on circuit breakers or electrical wiring.
- Ensure proper grounding and wiring according to local electrical codes and standards.
- Do not attempt to install or service this device if you are not a qualified electrician.
- Use appropriate personal protective equipment (PPE) such as insulated gloves and safety glasses.
Installation and Setup
The Siemens Q3015 circuit breaker is designed for plug-in mounting in compatible Siemens load centers. Follow these general steps for installation:
- Preparation: Ensure the main power to the electrical panel is turned off and verified with a voltage tester. Open the panel cover.
- Identify Slot: Locate an available slot in your Siemens load center that accepts CTL type QT breakers.
- Mounting: Align the breaker's clips with the bus bar and push firmly until it clicks securely into place. The duplex design means it occupies one 1-inch space on the bus bar.
- Wiring: Connect the appropriate circuit wires to the terminals on the breaker. The Q3015 has two distinct poles (30 Amp and 15 Amp). Ensure the correct wire gauge is used for each amperage rating (e.g., 10 AWG for 30A, 14 AWG for 15A). Tighten terminal screws to the manufacturer's specified torque.
- Cover Replacement: Once all connections are secure and verified, replace the panel cover.
- Power Restoration: Restore power to the main service panel.

Operation
Circuit breakers like the Siemens Q3015 are designed to protect electrical circuits from damage caused by overcurrent or short circuit. When an overload or short circuit occurs, the breaker will automatically "trip" to the OFF position, interrupting the flow of electricity to that circuit.
- Turning ON: To turn a circuit ON, push the breaker handle firmly to the ON position.
- Turning OFF: To turn a circuit OFF, push the breaker handle firmly to the OFF position.
- Resetting a Tripped Breaker: If the breaker trips, it will move to a central or fully OFF position. To reset it, first push the handle firmly to the full OFF position, then push it to the ON position. If the breaker immediately trips again, there is likely a persistent fault in the circuit that needs to be addressed by a qualified electrician.
Maintenance
Siemens circuit breakers are generally maintenance-free. However, periodic visual inspection is recommended:
- Visual Inspection: Annually inspect the breaker for any signs of physical damage, discoloration, or loose connections.
- Dust and Debris: Ensure the area around the breaker within the panel is free from dust and debris, which can impede proper operation or cause overheating.
- Professional Check: Consider having a qualified electrician inspect your electrical panel and breakers every few years, especially if you experience frequent tripping or notice any unusual electrical behavior.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Breaker trips frequently. | Overloaded circuit, short circuit, or ground fault. | Reduce load on the circuit. Unplug appliances. If it continues, consult an electrician to check for short circuits or ground faults. |
| Breaker will not reset. | Persistent fault (short circuit, severe overload) or internal breaker damage. | Ensure all appliances on the circuit are unplugged. Try resetting again (OFF then ON). If it still won't reset, do not force it; call a qualified electrician. |
| No power to circuit, but breaker is ON. | Loose wiring connection, faulty outlet/fixture, or internal breaker failure. | Check connections at the breaker and outlets/fixtures (with power off). If problem persists, consult an electrician. |
