Eaton Quicklag BAB Series Two-Pole Thermal-Magnetic Circuit Breaker

Eaton Quicklag BAB Series Two-Pole Thermal-Magnetic Circuit Breaker

The Eaton Quicklag BAB Series Two-Pole Thermal-Magnetic Circuit Breaker is a family of industrial thermal-magnetic breakers engineered for dependable overcurrent protection in commercial and industrial electrical distribution systems, available in amperage ratings from 15A through 80A across the BAB2015, BAB2020, BAB2040, BAB2060, and BAB2080 models. Every breaker in the series is rated for 240V across two poles and carries a 10 kAIC interrupt rating, giving it the capacity to safely clear short-circuit currents while protecting downstream branch circuits and connected equipment from sustained overloads. Each model uses a bolt-on mounting configuration, allowing it to be securely fastened directly to the bus of a compatible panelboard rather than simply plugged in, which helps maintain a tight, vibration-resistant connection in demanding industrial environments. As part of Eaton's BAB / Q7 platform, these breakers are built with a non-interchangeable trip unit fixed to each model's specific amperage rating for consistent, predictable performance.

Key Features

• Amperage Range: Available in 15A, 20A, 40A, 60A, and 80A two-pole models sized for branch-circuit and feeder overcurrent protection in commercial and industrial panelboards.
• Interrupt Rating: 10 kAIC short-circuit interrupt rating shared across the series gives the fault-current withstand capacity required for demanding industrial and commercial services.
• Voltage Rating: Rated at 240V across two poles, suitable for standard single-phase and multi-wire branch circuits found in commercial and industrial 240V systems.
• Bolt-On Mounting: Bolt-on mounting style bolts directly to the panelboard bus bar for a secure, vibration-resistant connection well suited to industrial settings subject to shock and movement.
• Thermal-Magnetic Trip Mechanism: The Quicklag thermal-magnetic trip combines a thermal element for sustained overload protection with a magnetic element for fast-acting short-circuit tripping.
• Two-Pole Configuration: Two-pole design allows each breaker to simultaneously interrupt both ungrounded conductors of a 240V circuit for complete disconnection.
• Series & Trip Type: Part of Eaton's BAB / Q7 series with a non-interchangeable trip unit fixed to each model's amperage rating, ensuring consistent protection coordination.
