Eaton Cutler-Hammer EB3020 20A 3P 240V Circuit Breaker, Bolt-On | AmpState

The Eaton Cutler-Hammer EB3020 is a bolt-on, 20 Amp, 3-pole, 240V circuit breaker designed for reliable circuit protection in panelboards, load centers, and electrical distribution systems. Built for everyday electrical work, this breaker fits installations where compatibility with the original BOM matters for service and upgrades.

Why choose the EB3020 for your electrical panel?

• Bolt-on mounting provides a secure, vibration-resistant connection that reduces the risk of loose terminations in busy electrical rooms.
• Three poles at 240V deliver controlled, balanced distribution across multi-phase panels, supporting common 3-pole configurations found in commercial spaces.
• Exact BOM compatibility helps you align spare parts with the original part numbers, simplifying inventory and future maintenance.
• Replacement and spare-friendly — keep a stock of EB3020s to speed field service and minimize downtime when a breaker needs replacement.
• Trusted Eaton Cutler-Hammer quality with a track record of reliability in panelboards and distribution equipment.

Applications and use cases:

• Primary use in panelboards and load centers that require a 3-pole 240V bolt-on breaker for protecting feeders, motors, or multi-circuit branches.
• Ideal for replacement projects where the original part number BOM must be preserved to ensure compatibility with existing accessories and bus bars.
• Practical as a spare for facilities maintenance programs to reduce downtime during scheduled or emergency service events.
