Product details

Siemens 5SY3225-7 SENTRON MCB — 25 A, 2-Pole, C-Curve

The Siemens 5SY3225-7 is a SENTRON 5SY3 series miniature circuit breaker rated 25 A at 400 V AC, 2-pole (2P), with a C tripping characteristic. It breaks fault currents to 4.5 kA per EN 60898 and 6 kA per IEC 60947-2; for DC circuits the interrupting rating reaches 15 kA at 72 V per IEC 60947-2.

Combined top and bottom terminals let you loop through without extra junction blocks. IP20 with conductors connected; mount in any position.

Halogen-free and silicon-free construction. Humidity tolerance: 95 % at 55 °C, derating to 35 % at 75 °C. Overvoltage category III, energy limiting class 3. Touch-protected terminals. The 5SY3225-7 is sealable for tamper-proof installations.

Frequently asked questions

What is the breaking capacity of 5SY3225-7?

The 5SY3225-7 has a rated breaking capacity of 4.5 kA per EN 60898 and 6 kA per IEC 60947-2 at 400 V AC. For DC circuits, it is rated 15 kA at 72 V per IEC 60947-2.

Where can I buy 5SY3225-7?

The Siemens 5SY3225-7 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.

Will 5SY3225-7 drop into a panel specified around 5SY3132-6 without rewiring?

Both are 2-pole SENTRON MCBs on a 36 mm DIN-rail footprint, so the mechanical fit is the same. The 5SY3225-7 is rated 25 A C-curve versus the 5SY3132-6 which is a different rating — verify the load current before swapping; the terminals accept the same 0.75–35 mm² conductors.
