Why Choose the TE Connectivity 1SNA190004R2300 D185/55.FF Power Terminal?
The TE Connectivity 1SNA190004R2300 is a heavy-duty D185/55.FF feed-through power terminal block designed for high-current electrical distribution in industrial control panels, switchgear and power systems. Part of the established TE Connectivity ENTRELEC SNA terminal block range, it provides a robust connection point for large conductors where dependable power distribution and mechanical connection integrity are essential.
Designed for conductors up to 185 mm², the D185/55.FF provides a maximum contact current rating of 353 A. Its two-position feed-through configuration uses two M12 studs for cable-lug connections, providing a secure termination method well suited to high-current industrial wiring and applications exposed to vibration or thermal cycling.
The 1SNA190004R2300 has a 55 mm spacing and mounts onto standard TH35-7.5 or TH35-15 DIN rail. The terminal supports an operating voltage of 600 V AC under the manufacturer's listed operating characteristics and has an operating temperature range of -55–110 °C, making it suitable for demanding industrial power distribution environments.

Reliable High-Current Power Distribution
High-current power terminal blocks provide secure connection points for large conductors used in industrial electrical distribution. The D185/55.FF uses cable lugs mounted onto M12 studs rather than relying on a conventional stripped-wire connection, providing a robust mechanical and electrical interface for demanding power circuits.
The TE Connectivity ENTRELEC D185/55.FF combines a 353 A maximum contact current rating with DIN-rail mounting and a compact 55 mm terminal spacing. This makes it particularly suitable for incoming supplies, high-current distribution circuits and other power connections where an organised, accessible and serviceable panel layout is required.
Typical Applications
- Industrial power distribution panels.
- High-current control cabinet connections.
- Switchgear and electrical distribution systems.
- Industrial machinery and production equipment.
- Incoming and outgoing power connections.
- High-current cable-lug termination.
- OEM electrical equipment manufacturing.
- DIN-rail-mounted industrial power assemblies.
