Siemens U01MN6 - 120 V Circuit Breaker | AmpState

Siemens U01MN6 is a 120V molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Its compact footprint helps you maximize panel space without sacrificing protection, making it a practical choice for both new installations and panel upgrades.

• Compact molded case design maximizes usable space inside the panel, helping you fit more circuits neatly and safely.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining heat-based overload sensing with magnetic short-circuit sensing. This means fewer nuisance trips and reliable shutoff during faults.
• OEM-compatible—specifically designed to pair with matching Siemens loadcenters and panelboards, ensuring correct fit, electrical characteristics, and consistent performance across Siemens systems.
• Versatile for multiple environments—suitable for residential, commercial, and light industrial applications where dependable branch circuit protection matters.

The thermal-magnetic mechanism protects wiring and connected devices by responding appropriately to both sustained overloads and sudden short circuits. Over time, this translates to safer operation, reduced risk of damage to electrical equipment, and more predictable panel behavior under varying loads and temperatures.

Ideal use cases include upgrading existing Siemens panels in homes, small offices, or retail spaces; protecting lighting and receptacle circuits in commercial settings; and serving as a reliable protection option for light industrial branch circuits where space in the panel is at a premium.
