Product details

The unit switches the neutral conductor (2-pole switching), so the load is fully isolated when the breaker trips or is manually opened. IP20 finger-safe terminals are standard for enclosed panel mounting.

What the B-curve and 3 kA rating mean for fit

At 10 A, the breaker will hold a continuous 10 A load and trip instantaneously between 30 A and 50 A. Overvoltage category 3 and energy limiting class 3 confirm it is rated for fixed-installation use and will limit let-through energy to protect downstream wiring.

Snap-on DIN rail mount, 2 width units (36 mm at 18 mm/module). 55 mm installation depth fits standard 60 mm deep enclosures. The neutral pole is switched internally — no separate neutral bar needed downstream of this breaker. IP20 rated for enclosed panel use only.

Frequently asked questions

Where can I buy 5SQ2260-0KA10?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the difference between 5SQ2260-0KA10 and 5SQ2270-2YA04?

Both are 2-pole SENTRON 5SQ breakers with the same 3 kA breaking capacity, 400 V rating, and 55 mm depth. The 5SQ2260-0KA10 is a B-curve 10 A breaker with neutral switching; the 5SQ2270-2YA04 is a C-curve 4 A breaker. The C-curve (5–10× In) suits motor or transformer loads with higher inrush; the B-curve fits general-purpose circuits. The 10 A rating on the 5SQ2260-0KA10 supports a higher continuous load than the 4 A peer.

What is the number of poles on 5SQ2260-0KA10?

It is a 2-pole breaker (2P), switching both phase and neutral.

What type of voltage does 5SQ2260-0KA10 support?

It is rated for AC/DC operation, 400 V AC at 50 Hz.
