The main circuit accepts 400 to 690 V AC at 50/60 Hz, so it covers standard European 400 V three-phase and the 690 V mining or marine distribution systems without a separate transformer tap. Control is 24 V DC, which keeps the logic supply isolated from the power section — standard practice for panels where a 24 V DC bus already feeds the PLC and safety relay chain. Built-in electronic overload protection (with a current limit adjustable 1.5 to 7 times Ie) means you do not need a separate thermal overload relay in the motor circuit, provided the ambient stays within 0 to +50 °C and the service factor of 115 % is not exceeded continuously. ## Ramp and start profile The ramp time is adjustable 0 to 120 seconds, and the initial voltage during start can be set between 30 and 70 % of line voltage, with a step-down voltage special ramp from 100 down to 30 % — this gives you the flexibility to tune the acceleration for a loaded conveyor start or a pump with low static head, provided the starting capacity of 3x Ie for 15 seconds is not exceeded. The unit includes run, fault, bypass, and overload signal relays, plus a red fault LED and yellow protection LED — enough status feedback to wire directly into a PLC input card without an extra interface module. The PST44 series is a mature, widely deployed platform, so documentation — including the datasheet 1SFC132005C0201 and instruction manual 1SFC132003M0201 — is readily available for panel builders who need to verify terminal torque (0.5 N·m on the control circuit) or main-circuit cable sizing (rigid 1 x 10 to 95 mm²).","metaTitle":"ABB 1SFA895004R7000 PST44 Soft Starter, 44 A In-Line","metaDescription":"ABB PST44-690-70 soft starter 1SFA895004R7000.
