PSTX85-600-70 45kw 37kw ABB Soft Starter Plc Programming Controller Module

1. High-Performance Soft Starter for Small-to-Medium Motors:The PSTX85-600-70 is a premium solid-state soft starter from ABB’s PSTX series, designed for 600 V AC systems with a rated current of 85 A, capable of starting motors up to approximately 45 kW (60 HP)—ideal for pumps, fans, and compressors.

2. Soft Starting with Reduced Electrical & Mechanical Stress:Uses thyristor phase control to gradually ramp up motor voltage, limiting inrush current to 1.5–5x full load current, minimizing voltage dips and mechanical shock during start-up.

3. Integrated Bypass Contactor for High Efficiency:Built-in bypass contactor automatically switches to direct-on-line operation after start-up, bypassing the thyristors. This reduces power losses and heat generation, improving energy efficiency during continuous operation.

4. Comprehensive Motor and Load Protection:Features include overload, stall, phase loss, phase imbalance, thyristor overtemperature, start time-out, and underload protection (useful for pump dry-run detection)—ensuring safe and reliable operation.

5. Multiple Start/Stop Modes for Complex Loads:Supports voltage ramp, current limit, kick start (Kick Start™), soft stop, and pump stop modes—ideal for high-inertia or sticky loads such as sludge pumps or mixers.
