Feature → Business Impact → Application: Ekip Dip LS/I electronic release provides fast, reliable tripping with precise control, reducing downtime and safeguarding critical loads in manufacturing lines and pumping stations. The 4P, 100 A nominal current and 600 V rating enable protection of multi‑branch feeders in main switchgear, improving panel reliability and standardization across sites. Front terminal connections simplify installation and maintenance in tight control cabinets, shortening commissioning time and lowering labor costs. Busbar compatibility from 32.5 to 100 mm² offers flexible wiring options for evolving installations, supporting upgrade projects without replacing existing busbars. A compact footprint with 120 mm × 130 mm footprint fits standard enclosures, while a 6 N·m tightening torque ensures secure terminations. Low energy loss per pole (4.2 W) contributes to overall panel efficiency and reduced operating costs.
