Siemens QE130H 30A 1-Pole 120 V Circuit Breaker Potential Transformer

Siemens QE130H 30A 1-Pole 120 V Circuit Breaker delivers reliable, precise overcurrent protection for a dedicated branch circuit in 120-volt panels. Built on Siemens’ trusted engineering, this QE130H device is designed to trip quickly when current exceeds its 30-amp rating, safeguarding wiring and connected equipment from damage and reducing the risk of electrical faults.

Key specifications

• Current rating: 30 A
• Pole: 1
• Voltage rating: 120 V
• Part number: QE130H
• Brand: Siemens

Why this matters

In any electrical setup, having the right protection on each branch circuit is crucial. The QE130H provides fast, predictable interruption when faults occur or when a circuit becomes overloaded. This helps prevent overheated wires, damaged outlets, and potential fire hazards, while keeping your panel organized with a consistent Siemens single-pole design.

Ideal use cases

• Dedicated 120 V circuits for appliances, heaters, or equipment drawing up to 30 A
• Residential or light commercial panels requiring a reliable Siemens-compatible replacement
• Situations where a single-pole, 120 V protection device is the right fit for one branch circuit

Practical notes and installation tips

For best results, pair the QE130H with appropriate wiring that matches or exceeds its 30 A rating (consult local electrical codes or a licensed electrician). Typical installations favor conductors suitable for 30 A at 120 V and proper strain relief within the load center. Always ensure compatibility with your specific panel model and follow all safety guidelines during installation and maintenance.

What sets the QE130H apart

Unlike generic breakers, the QE130H is a genuine Siemens component, offering consistent performance within Siemens-load centers and compatible panels. Its single-pole form factor provides straightforward, space-efficient protection for a single 120-volt circuit, while maintaining clean panel organization and predictable operation across your electrical system.

If you’re updating an aging panel or replacing a blown or worn breaker, the QE130H 30A 1-Pole 120 V circuit breaker is a purpose-built choice that aligns with your existing Siemens ecosystem and delivers dependable, lasting protection for your home or small business circuits.
