ABB EHDB360 Spectrum Drive Contactor

ABB EHDB360 Spectrum Drive Contactor is a three‑pole drive switch rated for 360 A continuous current, designed for ABB Spectrum Drive DC drive systems in mid‑ to high‑power motor applications. The main contacts are rated up to 600 V (DC) and 360 A, with a 100–250 HP range at 600 V, making it suitable for a wide range of industrial motors. Available variants include EHDB360C‑1L (120 V AC coil) and EHDB360C‑QL (125 V DC coil); several EHDB models feature withdrawable coils, including EHDB220, EHDB280, and EHDB360 for easier maintenance. Coil data varies by variant, but typical AC coil input is around 1200 VA with an inrush of about 65 VA and holding around 22 VA, while DC coil consumption is about 630 W with corresponding inrush/holding behavior; operating times depend on coil type, with AC close ~20–30 ms and open ~7–15 ms, and DC close ~30–40 ms and open ~27–37 ms. Some configurations include auxiliary contacts to support control circuits in the same device.
