ABB PSE25-600-70

ABB PSE25-600-70 is a compact three-phase softstarter that protects and controls small to medium motors by ramping voltage during start and stop. It accepts a main voltage range of 208–600 V AC and a control supply of 100–250 V AC (50/60 Hz). The device is rated for 25 A nominal operating current at line connection, with a current‑ramp range of 7.5–25 A, and it includes an integrated bypass for compact installation and energy efficiency. With an IP20 protection rating and screw-terminal connections, it is designed for dry, indoor environments and straightforward wiring; the unit weighs about 3.2 kg. The PSE25-600-70 features an illuminated display with language-neutral symbols and supports two-phase control via voltage or torque ramp, enabling smooth acceleration and deceleration. It offers RUN, TOR, and Event signaling through a relay output, and supports multiple control paths: hardwired Start/Stop (and Reset), Modbus RTU via an optional fieldbus adapter, or an external keypad (IP66) option. Built-in motor protection includes current limit, kickstart, analog output, EOL, underload, and rotor‑lock protection to guard against abnormal network and load conditions. Typical ABB applications include pumps, fans, compressors, and conveyors where compact soft-start control is desired, making the PSE25-600-70 a cost‑efficient choice for reducing mechanical stress and energy use in small-to-medium motor drives.
