Eaton | BAB2110S1 | Circuit Breaker | 110A | 2-Pole | 240V | Bolt-On

Meet the Eaton BAB2110S1 Circuit Breaker — a purpose-built 110 A, 2-Pole, 240 V bolt-on solution designed for maintenance, retrofit, and replacement projects where exact specifications matter. This breaker delivers dependable overcurrent protection for 240-volt circuits, built into a robust bolt-on design that secures firmly in compatible panels and reduces the risk of connection loosening over time.

Key specifications

• Amperage: 110 A
• Poles: 2-Pole
• Voltage: 240 V
• Mounting: Bolt-On
• Part number: BAB2110S1

Why this specific combination matters: the 110 A rating protects high-load 240-volt circuits without tripping during normal startup surges, while the 2-pole design ensures both hot legs are treated simultaneously, maintaining balanced protection across the circuit. The bolt-on mounting provides a secure, vibration-resistant connection ideal for panels that rely on a solid mechanical interface for long-term reliability.

Who it's for and practical use cases

• Electrical professionals performing panel maintenance, retrofits, or replacements in update-to-spec projects.
• Facilities and service crews replacing worn breakers in 2-pole, 240 V circuits that require exact compatibility with the BAB2110S1 reference.
• Projects where a precise part reference is essential to ensure correct fit and ratings, minimizing guesswork during installation.

Use cases include protecting 240-volt circuits in commercial or residential panels, replacing aged or failed breakers, and upgrading systems to meet current safety and performance standards. Because the part number is the best reference for compatibility, always verify that BAB2110S1 matches your panel model and rating before ordering.

Installation and compatibility tips

• Verify that your panel accepts bolt-on, 2-pole breakers of 240 V and 110 A rating before purchasing.
• Before installation, ensure the main power is de-energized and follow the panel manufacturer’s torque and seating recommendations.
• Keep a record of the part number BAB2110S1 for future maintenance cycles and warranty considerations—this is the most reliable reference for compatibility.

With Eaton's reputation for dependable electrical protection, the BAB2110S1 offers a precise, secure solution for critical 240-volt circuits. It’s the thoughtful choice when you need a direct, compatible replacement that you can trust to perform consistently over time.
