100% Original & Authentic In-Stock & Fast Shipping Expert Technical Support 12-Month Warranty

Core Features

✓ Dual Connection Flexibility: Supports standard In-Line setups (up to 400 kW / 720A at 400V) and Inside Delta wiring, scaling up to handle massive loads up to 1247A.
✓ Wide Voltage Range: Engineered for global compatibility, effortlessly handling main circuit voltages from 208 to 600 V AC.
✓ Advanced Pump Control: Features specifically tuned torque control algorithms that eradicate pipeline pressure spikes (water hammer) during pump starts and stops.
✓ Stable Control Supply (Us): Operates reliably on a 100 ... 250 V AC control supply, with an isolated 24 V DC control circuit (Uc) for superior logic stability.
✓ Frequency Versatility: Seamlessly adapts to both 50 Hz and 60 Hz main circuit frequencies.

Frequently Asked Questions

Q: What is the benefit of the 115% service factor on this ABB softstarter?

A: This built-in safety margin allows the softstarter to operate continuously at 115% of its 720A nominal rating (up to roughly 828A) without tripping. It provides a crucial operational buffer for applications prone to sudden, unpredictable load fluctuations.

Q: When should I wire the PSTB720-600-70 in an "Inside Delta" configuration?

A: While the standard In-Line connection supports up to 720A, utilizing an Inside Delta connection places the softstarter inside the motor delta circuit. This effectively increases its current-handling capacity up to a massive 1247A, enabling you to control much larger motors with a physically smaller starter footprint.

Q: Does this softstarter support remote diagnostic and current monitoring?

A: Absolutely. It features a programmable analog output (configurable to standard 4-20mA or 0-10V signals) that transmits real-time motor current data. You can easily integrate this into your PLC or SCADA system for continuous remote oversight and data logging.
