Overvoltage category 3 and energy limiting class 3 mean it is designed for fixed-installation coordination — it limits let-through energy enough to protect downstream cabling and loads when a fault occurs within its 3 kA envelope.","metaTitle":"Siemens 5SQ2370-0KA10 SENTRON MCB, 3-pole C 10A 3kA","metaDescription":"Siemens SENTRON 5SQ2370-0KA10 miniature circuit breaker, 3-pole, C-curve, 10 A rated, 3 kA breaking capacity per EN 60898 at 400 V AC.

The only difference is the current rating: 10 A on this part versus 4 A on the 2YA04. If the branch load is ≤10 A and the wiring and upstream protection are sized for 10 A, it is a direct mechanical swap."},{"question":"Where can I buy 5SQ2370-0KA10 and get current pricing?","answer":"This part is sourced to order against an RFQ through independent distribution.
