Both ends terminate in HAN 10E connectors (male on one side, female on the other), making it a plug-and-play link between an ECOFAST-compatible drive or motor and the control cabinet. The 2.5 mm² power conductors handle the motor supply current for drives up to the ECOFAST system's rated range — typically 4–7 kW at 400 V depending on cable length and ambient. The shield is continuous through the HAN 10E housings, which keeps the EMC emissions and immunity within IEC 61800-3 limits for industrial environments. Length is specified at order time in 10 cm increments between >3 m and <5 m. That means you order the exact drop length — no coiling excess in the cabinet, no field-cutting a molded connector. The HAN 10E is a rugged industrial rectangular connector rated for IP65 when mated, so the cable assembly suits machine-mounted junction boxes or direct motor connections in washdown areas. ## What to watch when specifying The HAN 10E connectors are keyed for ECOFAST pin assignments — verify the pinout matches your drive's brake and thermistor wiring before ordering. The male/female pairing is fixed: one end is male, the other female, so the cable has a defined direction. If your cabinet panel uses a bulkhead feed-through, confirm which gender lands on the drive side.","metaTitle":"Siemens 3RK1911-0CU30 ECOFAST Motor Connection Cable, Shield","metaDescription":"Siemens 3RK1911-0CU30 ECOFAST motor connection cable, shielded, 4x2.5 mm² + 4x0.75 mm², preassembled HAN 10E both ends.
