ABB S1M335 Soft Starter For 3-Phase 690V Motors 65 Amp

ABB S1-M3-25 power infeed block (S1M335) for three-phase systems up to 690 V, rated at 65 A, is designed to feed ABB MS116 and MS132 cabinet assemblies. This flat-style block accepts 25 mm² stranded conductors and provides a robust three-phase input interface at 690 V AC for motor starters and other control gear. The component is catalogued as 1SAM201907R1103 and sits in the S1-M3 family of power infeed blocks. Ideal for mid-sized automation installations, it streamlines cabinet wiring by consolidating three-phase power entry into a dedicated, durable feeder block. Typical applications include supplying motor starters, contactors, and related control circuits inside low-voltage ABB switchgear enclosures, where a reliable 690 V three-phase feed is required.
