Product details

The 1SFA894004R7000: Built-in electronic overload protection (adjustable 1.5–7× Ie) eliminates the need for a separate overload relay, saving panel space and wiring. The 100–250 V AC control supply voltage covers common line voltages across regions.

Ratings & Protection

Starting capacity is 3× Ie for 15 seconds — enough for most standard-load starts. The current limit function is adjustable from 1.5 to 7× Ie, and the initial voltage during start can be set between 30–70% of line voltage. A step-down voltage special ramp (100–30%) handles pump deceleration to prevent water hammer. Service factor of 115% provides headroom for continuous overload conditions. Ambient operating temperature range is 0 to +50 °C. Main terminals carry IP10 protection per IEC 60529 and IEC 60947-1.
