Eaton BAB2020S - 20 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Eaton BAB2020S — a robust 20A, 240V, 2-pole bolt-on molded case circuit breaker designed to guard your electrical panel against overcurrent and short-circuit events. Built for dependable protection in panelboards and load centers, this breaker is engineered to stay secure and perform consistently, even in vibration-prone environments.

• Bolt-on mounting for a rigid, vibration-resistant connection: The bolt-on design creates a solid bus connection that resists loosening from motor starts, door slam, or building movement, reducing nuisance trips and downtime.
• Thermal-magnetic trip unit for precise protection: Combines a thermal element for overload detection with magnetic trip for fast short-circuit response, delivering stable, repeatable protection across temperature and load conditions.
• 2-pole, 20A at 240V: Suitable for branch circuits in residential, commercial, and light industrial settings, including multi-wire branch circuits where both poles must trip together.
• Molded case construction for durability and insulation: A rugged housing that withstands field service, with clear terminal access and compatibility with OEM panelboards and load centers.
• OEM-ready compatibility: Designed to integrate with matching Eaton OEM load centers and panelboards for compliant, streamlined replacements or upgrades.

Who this is for: Installers and maintenance professionals seeking a reliable, easy-to-replace 2-pole breaker that maintains panel integrity and supports consistent protection across a wide range of facilities—from home service panels to light commercial systems.
