Product details

Lifecycle & compliance: active, dual-standard certified

The 5SY5210-7: Production status is current — no end-of-life notice, no last-time-buy window. The breaker carries dual certification to IEC/EN 60898-2 and UL 1077, covering both European and North American installation codes. Halogen-free and silicon-free construction simplifies disposal and avoids contamination in clean-room or coating environments. Sealable terminals allow lockout/tagout compliance without add-on accessories.

Panel fit: 2 MW, any orientation, quick assembly

The quick-assembly fastening method lets you clip it in and out without tools.

Frequently asked questions

What is the breaking capacity of 5SY5210-7?

10 kA per IEC/EN 60898-2 and 15 kA at DC per IEC 60947-2. The higher figure applies when the breaker is applied under the industrial standard rather than the domestic-standard curve.

Will 5SY5210-7 drop into a panel specified around 5SY5240-7 without rewiring?

Physically yes — both are 2-pole, 2 MW units on the same DIN-rail footprint. The difference is the tripping characteristic: 5SY5210-7 is C-curve, while 5SY5240-7 is D-curve. If the original design called for D-curve to handle very high inrush (large motors, welding transformers), swapping to C-curve may cause nuisance trips. Check the load type before substituting.

What compliance documentation does Siemens provide for 5SY5210-7?

The breaker is certified to IEC/EN 60898-2 and UL 1077. It is halogen-free and silicon-free. RoHS, REACH, and CE declarations are standard for SENTRON products; specific documents are available on request with the RFQ.

Where can I buy 5SY5210-7?
