Eaton QCHW3030H - 30 A, 240 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton QCHW3030H—a compact, reliable guard for 30A, 240V circuits. This 3-pole molded case circuit breaker is designed to deliver dependable branch circuit overcurrent and short-circuit protection inside panelboards and load centers, making it a trusted choice for residential, commercial, and light industrial applications.

Why this breaker stands out

• Space-conscious design: The molded case construction is engineered to maximize panel space, helping you fit more circuits neatly inside tight enclosures without sacrificing performance.
• Thermal-magnetic protection: A dual-action trip unit provides stable, repeatable protection by filtering ordinary overloads with the thermal element and delivering instantaneous response to short circuits with the magnetic element.
• Three-pole clarity for 240V systems: With 3 poles, it ensures simultaneous disconnection across all conductors in multi-wire or 3-phase environments, promoting safety and proper coordination.
• OEM-compatible: Designed to pair with matching Eaton OEM load centers and panelboards, enabling straightforward replacement and dependable system coordination.
• Versatile applications: Ideal for protecting essential equipment in homes, small businesses, and light industrial setups that rely on 240V, 3-pole distribution.
