1sna115498r1700 – m6/8 d1.

Why Choose the TE Connectivity 1SNA115498R1700 M6/8.D1 Double-Level Terminal Block?

The TE Connectivity 1SNA115498R1700 is an M6/8.D1 grey double-level screw-clamp feed-through terminal block from the established ENTRELEC SNA range. Designed for industrial control panels, automation systems and signal wiring, it combines two terminal levels within a compact 8 mm-wide DIN rail footprint.

Unlike a conventional two-circuit double-level terminal, the M6/8.D1 provides one feed-through circuit with vertical interconnection and an integrated partition. This configuration electrically links the terminal levels while retaining the space-saving benefits of a double-deck design, making it useful for structured distribution and signal wiring where vertically interconnected connection points are required.

The M6/8.D1 is rated at 41 A and 800 V IEC, with an 8 kV impulse withstand voltage. It accommodates flexible conductors from 0.5–6 mm² and rigid stranded conductors from 0.5–10 mm², while compatibility with G32, TH35-7.5 and TH35-15 rails provides flexible installation in industrial terminal assemblies.

Key Advantages

• Double-level construction maximises connection density within an 8 mm DIN rail footprint.
• Vertical interconnection provides one electrically interconnected feed-through circuit across the two levels.
• Integrated partition supports organised terminal assembly construction.
• 41 A IEC rated current and 800 V IEC rated voltage.
• Accepts rigid stranded conductors up to 10 mm² and flexible conductors up to 6 mm².
• Compatible with G32, TH35-7.5 and TH35-15 DIN rails.

Key Features

• TE Connectivity / ENTRELEC M6/8.D1 feed-through terminal block.
• Part of the ENTRELEC SNA screw-clamp range.
• Double-level / double-deck configuration.
• One feed-through circuit with vertical interconnection.
• Four poles and two connection positions.
• 6 mm² / 8 AWG wire size.
• 41 A IEC, 50 A UL and 45 A CSA current ratings.
• 800 V IEC voltage rating with 8 kV impulse withstand capability.
• Grey polyamide 6.6 housing.
• IP20 protection with UL 94V-0 flammability rating.

Space-Saving Vertical Interconnection for Industrial Wiring

The defining feature of the M6/8.D1 is its vertical interconnection between the two terminal levels. Rather than providing two electrically independent feed-through circuits, the block uses its double-deck construction to provide one interconnected circuit across four poles, allowing multiple connection points to share the same electrical potential within a compact terminal footprint.

Its screw-clamp technology provides secure conductor termination, while the 41 A IEC current rating, 800 V IEC voltage rating and 8 kV impulse withstand capability support demanding industrial installations. The combination of vertical interconnection, integrated partition and DIN rail mounting makes the M6/8.D1 a practical choice for structured signal and distribution wiring.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Vertically interconnected terminal circuits.
• Signal and control wiring.
• Marshalling terminal assemblies.
• Machine control and production equipment.
• Switchgear and controlgear assemblies.
