Eaton LGH360033W - 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for reliability in demanding electrical environments, the Eaton LGH360033W is a 600 V, 3-pole bolt-on molded case circuit breaker (MCCB) designed to deliver precise overcurrent and short-circuit protection in panelboards and load centers. Whether you’re updating a residential service, outfitting a commercial distribution, or equipping a light industrial installation, this breaker helps keep circuits safe and uptime high.

Key Features

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping to minimize loosening and arcing in busy panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance across a range of currents, reducing nuisance trips while offering robust fault interruption.
• OEM-compatible design is engineered to pair with matching Eaton load centers and panelboards for straightforward replacement and installation.
• 3-pole, 600 V configuration is ideal for three-phase distribution in residential, commercial, and light industrial applications.

Performance and Protection

The LGH360033W uses a thermal-magnetic trip mechanism to address both sustained overcurrent and short-circuit events. This means faster, more predictable interruptions when faults occur, while maintaining dependable operation under normal load conditions. A solid bus connection from the bolt-on mount minimizes movement and loss of contact, supporting long-term reliability in environments with vibration or shifting loads.
