Eaton DNPL220230 - 30 A, 240 V Plug-In Circuit Breaker | AmpState

Meet the Eaton DNPL220230 — a plug-in molded case circuit breaker designed to protect your electrical system with clarity and reliability. At 30A and 240V, this device delivers dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers, making it a practical upgrade or replacement choice for residential, commercial, and light industrial environments. Available through AmpState, it adopts a fast plug-in connection for quick, tool-free installation and swift service when circuits change.

Key to its performance is the thermal-magnetic trip unit. The thermal element handles sustained overcurrent with precise, repeatable protection, while the magnetic element activates on high-energy faults for immediate response to short circuits. The result is predictable protection curves you can trust, reducing nuisance trips and safeguarding sensitive loads from power disturbances.

Why this matters for your panel

• Plug-in convenience: a secure, reliable connection that simplifies installation and minimizes downtime during upgrades or replacements.
• Consistent protection: thermal-magnetic operation provides stable trip behavior across varying temperatures and loads.
• OEM-aligned compatibility: designed to fit and function with matching Eaton OEM load centers and panelboards for seamless integration.
• Versatile applications: ideal for residential service panels, small-to-medium commercial panels, and light industrial subpanels that require robust branch-circuit protection.
