FAQs
The 1SBL371074R8311 uses screw terminals and IP20 coil terminals with a width of 82 mm, depth of 110 mm, and height of 108 mm. It fits standard 35 mm DIN-rail or panel mounting, and its auxiliary contact blocks can be added on the side, enabling straightforward integration into existing motor-control cabinets.
Main contacts are 3 NO, auxiliary contacts NO/NC, rated for AC-1 up to 115 A and AC-3 up to 65 A depending on voltage. Insulation voltage is 690 V, with a maximum short-time withstand current up to 1000 A for short durations. These ratings support reliable starting and switching of 3-phase motors in industrial settings.
Yes. The AX50–AX80 family targets motor control in conveyors and similar load profiles. With a 48 V control coil and 690 V main circuit rating, plus add-on auxiliary contacts for interlocking and safety circuits, it provides robust control and expandability for conveyors and material-handling equipment.
This device carries CE and UL certifications, RoHS and REACH declarations, CCC/CQC alignments, and EE-related harmonization marks. It also adheres to IP20 coil-terminal protection and IP10 main-terminal protection, supporting regulatory acceptance across multiple regions.
Maintenance benefits come from a reliable 125 A Ith rating and low power loss (6.5 W per pole AC-1), reducing heat and cooling needs. The modular add-on auxiliary blocks simplify future expansions, lowering total cost of ownership by minimizing replacement parts and enabling scalable control logic without rework.
