Why this breaker stands apart

• Secure bolt-on mounting: A rigid connection that resists loosening and vibration, preserving the integrity of the bus and protecting critical circuits.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection across a wide range of loads and ambient temperatures, reducing nuisance trips while safeguarding equipment.
• 3-pole design for 3-phase systems: Ideal for commercial and light industrial applications where balanced protection across all phases is essential.
• OEM-compatible: Engineered to integrate with matching Eaton load centers and panelboards, simplifying installation and maintenance.
• Durable, practical protection: Engineered for long-term service in panelboards and load centers, helping minimize downtime from overcurrent and short-circuit events.

Ideal applications and use cases

• New installations in commercial panelboards requiring reliable 3-phase protection up to 600V.
• Replacements in existing Eaton panelboards where a bolt-on MCCB is preferred for secure mounting and robust performance.
• Light industrial electrical rooms or service panels exposed to vibration or frequent maintenance, where a stable bus connection matters.
• Branch circuit protection for feeders and distribution within equipment rooms, ensuring quick isolation of faults with minimal impact on other circuits.
