Mounts via quick assembly system (DIN rail compatible) in any position. The 2-pole form factor means it switches both phase and neutral — common for single-phase subcircuits where disconnecting the neutral is required by local code or for railway DC applications. Combined terminals top and bottom simplify busbar and outgoing wiring.

Frequently asked questions
What is the breaking capacity of the 5SY4202-7KK11?
10 kA per EN 60898, 35 kA per IEC 60947-2 at 400 V AC, 15 kA per IEC 60947-2 at 72 V DC, and 5 kA per UL 1077 / CSA C22.2 No. 235.
What is the tripping characteristic of this MCB?
C-curve, meaning it trips at 5 to 10 times rated current. Suited for moderate inrush loads like contactors, relays, and small transformers.
Where can I buy the 5SY4202-7KK11?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Will the 5SY4202-7KK11 drop into a panel specified for the 5SY7210-7CC?
Both are 2-pole SENTRON MCBs on the same DIN-rail footprint (36 mm width, 2 width units). The 5SY4202-7KK11 is a 2 A C-curve; the 5SY7210-7CC is a 10 A C-curve. Same mechanical fit — the difference is the current rating and breaking capacity coordination. No rewiring needed if the ampacity matches the circuit.
