The BAB3040H model from Eaton Cutler-Hammer's QuickLag series is a specialized mini thermal-magnetic circuit breaker engineered for versatility and dependability in protecting electrical circuits. Rated for a current of 40.0 A, this breaker operates effectively at a voltage of 240 VAC and is configured for three-phase applications. With an interrupt rating of 10 kAIC at this voltage, it ensures safe interruption of fault currents, enabling protection for downstream equipment.
Structured with three poles, the BAB3040H utilizes a fixed thermal-magnetic trip unit. This design provides non-interchangeable functionality to deliver both long-time and instantaneous protection against overcurrents, which is essential for safeguarding electrical systems.
For installation, the unit features a bolt-on mounting style that facilitates secure attachment to panels or enclosures. It also includes box lugs as terminal types, allowing for solid connections with wires ranging from #14 to #4 AWG. This flexibility makes it adaptable to different wiring needs. Operation frequency for this circuit breaker ranges between a minimum of 50 Hz and a maximum of 60 Hz, fitting standard industrial and commercial applications.
