The TE Connectivity M300/42.FF 1SNA115149R2000 is a heavy-duty two-stud feed-through power terminal block designed for secure high-current connections in industrial power distribution, control panels and machinery. As part of the established TE Connectivity ENTRELEC SNA power terminal series, it combines a compact DIN rail format with robust stud connections for large-section conductors terminated with cable lugs.
The M300/42.FF features two M10 studs, providing secure mechanical and electrical connections for demanding power circuits. Its stud connection system is designed for cable lug mounting in accordance with NF C 20-130 and DIN 46234, making it particularly suitable for applications where reliable termination of high-current conductors is essential.
With a rated current of 269 A, rated voltage of 1000 V and rated cross-section of 120 mm², the M300/42.FF provides substantial power-handling capability. It accepts rigid conductors from 6–150 mm² and flexible conductors from 6–120 mm², while compatibility with G32 and TH35 DIN rails provides flexible installation within industrial electrical cabinets.
Stud terminal blocks provide a robust connection method for high-current conductors fitted with cable lugs. Unlike conventional screw clamp terminals where a stripped conductor is inserted directly into the terminal, the M300/42.FF uses M10 studs to secure cable lugs, providing a strong mechanical connection suited to large conductors and demanding power applications.
The M300/42.FF combines high current capacity with DIN rail mounting, allowing substantial power connections to be incorporated neatly into industrial control and distribution cabinets. Its 8000 A short-time withstand capability, wide operating temperature range and durable polyamide housing make it well suited to demanding industrial environments.
