Eaton QCR1030 - 30 A, 120 V, 1-Pole Circuit Breaker | AmpState

The Eaton QCR1030 is a compact, reliable 30-amp, 120-volt, 1-pole molded case circuit breaker designed to protect branch circuits in panelboards and loadcenters. Built for consistent performance, it provides both overload and short-circuit protection in a space-efficient package that helps you maximize panel capacity without sacrificing safety.

• Compact molded-case design minimizes footprint inside your panel, freeing space for other devices and simplifying wiring layouts.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to overloads (thermal) and short circuits (magnetic) for faster, more predictable tripping behavior.
• 1-pole, 30A, 120V configuration is well-suited for standard residential lighting, outlets, and other branch circuits that require solid protection at or below 30 amperes.
• OEM panel compatibility is designed to work with matching Eaton load centers and panelboards, ensuring coordinated protection and reliable performance.
• Versatile application ideal for residential, commercial, and light industrial environments where dependable overcurrent and short-circuit protection is essential.

Why this model stands out: the QCR1030 combines a space-saving form factor with a robust thermal-magnetic trip mechanism, delivering dependable protection without requiring larger breakers or more panel space. Its alignment with Eaton’s panel systems means fewer compatibility concerns and streamlined maintenance when replacing or stocking spares for compatible panels.
