Active SIRIUS direct starter with AS-Interface
The 3RK1315-6KS41-0AA0: Rated for 0.75 kW at 400 V and 0.7 hp at 460/480 V, it handles small three-phase motor loads in a single enclosure rated IP65 for washdown environments.
AS-Interface bus node with integrated I/O
This unit communicates via AS-Interface protocol (no PROFIBUS or PROFINET onboard) and provides 4 digital inputs addressed through an M12 plug — the fieldbus connection and sensor wiring terminate at the same IP65 enclosure. Supply voltage is 24 VDC nominal, with a permissible range of 20.4 to 28.8 V and an absolute maximum of 31.6 V — the onboard electronics regulate the bus power for the AS-i segment.
CLASS 10 trip curve and mounting flexibility
The CLASS 10 trip characteristic means the overload relay opens within 10 seconds at 7.2× rated current — standard for protecting standard induction motors during locked-rotor conditions. Mounting is via screw fixing in any orientation (vertical, horizontal, flat), though the recommended position is horizontal for optimal heat dissipation. The enclosure measures 159 mm deep × 294 mm wide × 215 mm tall.
Environmental ratings for industrial floors
IP65 protection means the enclosure is dust-tight and protected against low-pressure water jets — suitable for installation directly on machinery without a separate cabinet. Operating temperature range is -25 to +55 °C; storage and transport tolerate -40 to +70 °C. Vibration resistance is 7 mm / 2g, shock resistance 12g / 11 ms — the unit survives typical conveyor and pump vibration without loosening screw terminals.
