Snap-on DIN rail mounting per EN 60715. The 2-pole footprint occupies two modular spaces (36 mm at 18 mm per pole). Wire termination accepts up to 35 mm² conductor for the load side; torque settings per the terminal marking on the front face. The S800 series shares a consistent accessory range — shunt trip, auxiliary contacts, undervoltage release — all clip onto the same side profile.
The S801UE-K30 is rated 16 A, Trip Curve D, 2-pole, 277 VAC / 110 VDC, with a 6 kA interrupting rating at 277 VAC.
The S801UE-K30 is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.
Trip Curve D means the magnetic trip operates between 10x and 20x rated current (160 A to 320 A for this 16 A breaker), making it suitable for loads with high inrush like motors, transformers, and welding equipment.
No — the S201MUC-K2 is a 1-pole, 2 A, Curve K breaker; the S801UE-K30 is 2-pole, 16 A, Curve D. They differ in pole count, current rating, and trip characteristic, so they are not drop-in interchangeable without rewiring and recalculating the branch circuit protection.
