Product details

It is designed for residential and infrastructure branch-circuit protection per EN 60898 (4.5 kA breaking capacity) and IEC 60947-2 (5 kA).

At 30 °C ambient the breaker carries the full 50 A; at 40 °C it derates to 46.97 A, at 45 °C to 46 A, and at 55 °C to 42.01 A. The 4.5 kA breaking capacity per EN 60898 covers most residential and light commercial fault levels; the 5 kA per IEC 60947-2 gives a small margin for industrial panels with higher prospective short-circuit current.

It is halogen-free and silicon-free, and the housing is sealable for tamper-proofing. The product is designated per EN 61346-2 and IEC 81346-2 as function F (protective device). Touch protection is provided on the terminals. For compliance documentation (RoHS, REACH, CE, UKCA), the manufacturer provides declarations and certificates — these are typically available through the Siemens Industry Online Support portal or can be requested at quote time.

Frequently asked questions

What is the breaking capacity of 5SL3650-7?

The breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 400 V AC.

What is the difference between 5SL3650-7 and 5SL3340-7CC?

The 5SL3340-7CC is a 3-pole (3P) version without switched neutral, while the 5SL3650-7 is 3P+N with a switched neutral pole. Both share the same 50 A C-curve rating and 4.5 kA breaking capacity. The 5SL3650-7 occupies 4 MWUs versus 3 MWUs for the 3-pole variant. Panel wiring differs — the neutral pole must be accounted for in the 5SL3650-7.

Where can I buy 5SL3650-7 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your volume and delivery requirements.

What compliance documentation is available for 5SL3650-7?

The breaker is certified per EN 60898 and IEC 60947-2, with overvoltage category III and pollution degree 2. It is halogen-free and silicon-free. Manufacturer declarations for RoHS, REACH, CE, and UKCA are available through Siemens Industry Online Support or can be requested at quote time.
