TE Connectivity 1SNA115142R1100 M70/31.AF is a 50 mm² Entrelec SNA feed-through power terminal block with an M8 stud and screw-clamp connection for industrial power distribution.
£21.03
The TE Connectivity 1SNA115142R1100 is a robust M70/31.AF feed-through power terminal block from the established Entrelec SNA power terminal range. Designed for high-current electrical connections in industrial control panels, switchgear and machinery, it combines an M8 stud connection with a screw-clamp connection to provide a versatile transition between conductors.
The M70/31.AF uses a compact one-stud / one-clamp configuration with a 31 mm terminal spacing. The stud side supports cable-lug mounting in accordance with NF C 20-130 and DIN 46234, while the screw-clamp side provides convenient conductor termination. Multiple marking options help simplify circuit identification in complex electrical assemblies.
With a 50 mm² nominal cross-section and a 1000 V rated voltage, the 1SNA115142R1100 is designed for demanding industrial power-distribution duties. Depending on the applicable connection standard and conductor type, the terminal accommodates conductors up to 70 mm² and can be installed on common G32 and TH35 rails or directly onto a mounting surface.
Power terminal blocks provide secure connection and transition points for larger conductors within electrical distribution systems. The M70/31.AF combines two termination methods in one compact component, allowing a cable lug to be connected at the M8 stud while another conductor is terminated through the integrated screw clamp.
The TE Connectivity 1SNA115142R1100 is suitable for panel builders and machine manufacturers requiring dependable high-current connectivity with flexible mounting and conductor options. Its compatibility with common industrial rail formats also makes it suitable for maintenance and replacement within existing Entrelec SNA installations.
