Eaton BAB Quicklag Two-Pole Thermal-Magnetic Circuit Breaker, 240V

Eaton BAB2045 Quicklag BAB Series 2-Pole 45A Bolt-On Circuit Breaker

The Eaton BAB2045 is a Quicklag industrial thermal-magnetic circuit breaker engineered on Eaton's BAB platform for dependable branch circuit protection in industrial and commercial electrical systems. This two-pole, 45A breaker is rated for 120/240V AC service with a 10 kAIC interrupt rating, giving installers a breaker sized for demanding branch circuit and feeder applications. The breaker uses bolt-on mounting to secure directly to compatible panelboard bus assemblies, providing a stable, vibration-resistant connection for long-term panel performance. Its thermal-magnetic trip mechanism is a non-interchangeable, fixed Q7 series design, meaning the trip characteristics are factory-set and cannot be swapped in the field, supporting consistent, predictable overcurrent protection. As part of Eaton's Quicklag BAB series, the BAB2045 is built for industrial panelboards where reliable, code-compliant circuit protection is essential.

Key Features

• Bolt-On Mounting: Secures directly to compatible panelboard bus bars for a solid, vibration-resistant connection in industrial installations.
• Two-Pole Configuration: 2-pole design supports 120/240V AC circuits requiring dual-leg overcurrent protection.
• 45A Amperage Rating: Sized for 45-amp branch circuits feeding industrial and commercial loads.
• 10 kAIC Interrupt Rating: Thermal-magnetic trip mechanism is rated to interrupt fault currents up to 10,000 amps, helping protect downstream equipment and wiring.
• Non-Interchangeable Trip Unit: Fixed Q7 series trip design maintains factory-calibrated protection and helps prevent unauthorized field modification of trip settings.
• Thermal-Magnetic Protection: Combines thermal response for sustained overloads with magnetic response for short-circuit conditions.
• Quicklag Industrial Series: Part of Eaton's Quicklag BAB line of industrial-grade thermal-magnetic circuit breakers built for demanding panelboard environments.
• 120/240V AC Rating: Suited for standard single-phase industrial and commercial distribution voltages.
