Product details

The 5SY4310-7KK11: Mounts on DIN rail via the quick assembly system; any mounting position is allowed, saving layout constraints in crowded enclosures. The 3 MW unit width (54 mm) and 70 mm installation depth fit standard 18 mm pitch rails. Combined terminals at top and bottom accept conductors without special tools — touch protection is built in.

Lifecycle status is current. No PCN or EOL notice on file. Sourced to order against an RFQ through independent distribution — availability and current pricing confirmed at quote time.

Frequently asked questions

Where can I buy 5SY4310-7KK11?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 5SY4310-7KK11?

10 kA per EN 60898 and 20 kA per IEC 60947-2. The IEC 60947-2 figure governs industrial panel coordination.

What is the difference between 5SY4310-7KK11 and 5SY4140-7?

The 5SY4140-7 is a higher-rated variant (40 A vs 10 A) in the same SENTRON 5SY family, same 3-pole C-curve form factor. Panel footprint and terminal layout are identical — no rewiring needed for a swap if the load current changes.
