Product details

Rating and application fit

Breaking capacity is 4.5 kA per EN 60898 and 6 kA per IEC 60947-2, with a DC rating of 15 kA at 72 V per IEC 60947-2 and 5 kA at 400 V AC per UL 1077 / CSA C22.2 No. 235.

Terminal position is any orientation; the breaker is sealable for lockout/tagout compliance.

Rated for AC at 400 V and DC up to 72 V. Tripping characteristic B per EN 60898. Overvoltage category III, energy limiting class 3. The part is halogen-free and silicon-free. Touch protection is integrated. Neutral conductor switching is not provided — this is a 2-pole breaker switching both phases, not a 1P+N device.

Frequently asked questions

Where can I buy the 5SY3210-6 and how is it quoted?

The 5SY3210-6 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of the 5SY3210-6?

Breaking capacity is 4.5 kA per EN 60898, 6 kA per IEC 60947-2 at 400 V AC, 15 kA DC per IEC 60947-2 at 72 V, and 5 kA per UL 1077 / CSA C22.2 No. 235.

Will the 5SY3210-6 drop into a panel specified for the 5SL3120-6MB?

The 5SY3210-6 and 5SL3120-6MB are both 2-pole DIN-rail MCBs, but the 5SY3 series has a different breaking capacity profile and tripping curve. Verify the specific ratings and coordination study before substituting — the 5SY3210-6 uses a B curve, while the 5SL series may differ.
