Product details

The Siemens 5SL6203-7RC is a SENTRON miniature circuit breaker rated 3 A with a C tripping characteristic, 2-pole construction, and a breaking capacity of 7.5 kA per EN 60898.

For single-phase circuits, the rated voltage is 250 V AC; for multi-phase operation, it handles up to 440 V AC. The breaker is sealable, halogen-free, and silicon-free — relevant for installations with strict material compliance requirements or environments sensitive to outgassing.

IP20 with connected conductors — suitable for enclosed distribution panels, not for wet or outdoor locations without additional enclosure.

Frequently asked questions

Where can I buy 5SL6203-7RC and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote.

What is the difference between 5SL6203-7RC and 5SL4363-7?

The 5SL4363-7 is a 3-pole breaker (54 mm wide, 3 MW) with a 10 kA breaking capacity per both EN 60898 and IEC 60947-2, and a higher per-pole power loss of 5 W. The 5SL6203-7RC is a 2-pole (36 mm, 2 MW) with 7.5 kA per EN 60898 and 1.16 W per pole. They are not drop-in replacements: the 5SL4363-7 requires an extra modular width and has a higher fault-interrupt rating.

What compliance documentation does Siemens provide for 5SL6203-7RC?

The breaker is certified to EN 60898 for breaking capacity. It is halogen-free and silicon-free. The manufacturer provides the standard declaration of conformity and product documentation for the SENTRON series.
