Siemens QT1-1520 20A 1-Pole 240 V Circuit Breaker

Meet the Siemens QT1-1520 20A 1-Pole 240 V Circuit Breaker—a compact, reliable overcurrent protector designed for Siemens panels that accept QT-type breakers. With a 20 A current rating and a 240 V voltage rating, it safeguards a single circuit from overloads and short circuits, helping protect wiring and connected devices.

• Precise overcurrent protection — trips when current exceeds 20A, reducing heat buildup and electrical fire risk.
• Single-pole, 240 V design — ideal for protecting an individual 240 V circuit in compatible panels that specify QT-type breakers.
• Siemens QT1-1520 compatibility — part of the Siemens QT family, engineered to replace or upgrade in panels that accept QT-type breakers, ensuring seamless integration.
• Reliability you can trust — a factory-listed component designed to meet safety standards and support dependable panel performance.

Who it’s for: homeowners and light commercial settings needing a dedicated 20A 240 V protection for a specific circuit, whether you’re replacing an aging QT breaker or installing a new QT-series setup in a compatible Siemens panel.

Use cases and practical details: install this QT1-1520 to protect equipment or outlets fed from a 240 V supply in panels that specify QT-type breakers. It’s the right choice when you require exact part compatibility (same type, same rating) to preserve panel listings and ensure consistent trip behavior across your electrical system.

How it compares to alternatives: choosing the QT1-1520 ensures you’re pairing with Siemens’ established QT-series design for predictable performance and straightforward replacement in compatible panels, rather than generic breakers that may not match the panel’s listing or trip characteristics.

Installation note: always follow local electrical codes and the panel’s labeling when replacing or installing breakers. Use the exact part number QT1-1520 to maintain compatibility and system safety within your Siemens QT-type panel.
