Main features and advantages:

When it comes to technical performance, the ABB E5LA HENF105296R0001 stands out for its precision and reliability. At its core is ABB’s advanced thermal-magnetic protection technology, which combines two critical functions: thermal tripping for overload protection (gradually increasing currents) and magnetic tripping for short-circuit protection (sudden high-current faults). This dual-protection mechanism ensures that the breaker responds appropriately to different types of electrical anomalies, minimizing downtime while maximizing equipment safety. With a rated current of 500A and a breaking capacity of 50kA at 415V, the ABB E5LA HENF105296R0001 provides robust protection for medium to large electrical loads, making it suitable for everything from manufacturing machinery to building power distribution systems.

Another key advantage of the ABB E5LA HENF105296R0001 is its design for practicality and durability. The breaker features a compact, modular housing that fits standard DIN rail mounting systems, simplifying installation in switchboards, distribution panels, and control cabinets. Its rugged construction meets international standards for environmental resistance, including protection against dust and moisture (IP20 rating for the base unit), ensuring reliable operation in harsh industrial environments. For added versatility, the ABB E5LA HENF105296R0001 supports optional accessories like the Ekip Touch electronic trip unit, which adds digital monitoring capabilities, adjustable protection settings, and communication features for integration with building management or SCADA systems.
