Product details

What this MCB does for your panel

The Siemens 5SY8202-7 is a 2-pole miniature circuit breaker from the SENTRON family, rated at 400 V AC and 60 V DC with a C-curve trip characteristic. Its 70 kA interrupting capacity at 400 V AC per IEC 60947-2 means it can clear high-fault currents in industrial panels without cascading upstream — critical for selectivity in a motor control centre or distribution board. On DC circuits it still delivers 15 kA at 60 V (72 V max), covering battery-backed or solar combiner applications.

Any mounting position is allowed; the breaker is sealable for tamper-proofing in metered or safety-critical feeds.

Frequently asked questions

Will 5SY8202-7 drop into a panel built for 5SY4140-7?

Both are 2-pole SENTRON MCBs in the same 36 mm width and DIN-rail footprint, so mechanical fit is the same. The key difference is interrupting capacity: 5SY8202-7 carries 70 kA IEC vs the 5SY4140-7's lower rating — verify the panel's SCCR before swapping.

What compliance documentation does Siemens provide for 5SY8202-7?

The breaker is certified to IEC / EN 60947-2 and UL1077, halogen-free and silicon-free per the spec sheet. Standard RoHS and REACH declarations are available from Siemens documentation.
