1sna190003r2200 - d120/42ff power term

Why Choose the ABB D120/42FF Power Terminal Block?

The ABB D120/42FF power terminal block (Part No. 1SNA190003R2200) is a rugged, double-stud feed-through connector built for high-current applications up to 269 A at 1 kV AC. With two M10 studs and a 120 mm² cable capacity, it provides a secure, low-resistance connection for large conductors while DIN-rail clips enable fast panel integration.

Applications

Ideal for high-current distribution in:

• Switchboards and MCCs
• Renewable-energy combiner boxes
• Railway and traction power cabinets
• Industrial automation and heavy-duty machinery panels

The double-stud design allows straightforward daisy-chaining or secure feed-through of large conductors with minimal voltage drop.

What Installers Say

“Solid, high-amp terminal that snaps straight on the DIN rail. The twin M10 studs make parallel connections simple.” - LV Panel-Shop Supervisor

Key Features of the D120/42FF

• 120 mm² conductor capacity with 269 A current rating
• Double M10 stud arrangement for secure clamping
• Certified to IEC/NFC standards; UL 94 V-0 housing
• DIN-rail clip for fast, tool-free mounting
• Optional hinged IP20 shields for touch safety

Comparison with Other Power Terminals

Compared with smaller D70/28FF blocks, the D120/42FF handles 60 % higher current and larger conductors, while remaining more compact than 240 mm² alternatives-ideal when cabinet space and ampacity must be balanced.
