Product details

The Siemens SENTRON 5SL4150-7 is a single-pole miniature circuit breaker rated 50 A at 30 °C with a C tripping characteristic. Breaking capacity is 10 kA per both EN 60898 and IEC 60947-2 at 400 V AC, meaning it can safely interrupt a fault current up to that level without upstream cascading. The overvoltage category is III, suitable for fixed-installation distribution boards.

Derating and real-world current

At 40 °C it derates to 46.19 A, at 45 °C to 44 A, and at 55 °C to 39.81 A.

Panel fit and environment

Depth is 76 mm (installation depth 70 mm), height 90 mm, width 18 mm — one standard modular unit. Sealable with a lead seal for tamper-evident installations. Protection class is IP20 with connected conductors, plus touch protection on the terminals. Degree of pollution 2 (normal, non-conductive).

Frequently asked questions

Where can I buy the 5SL4150-7 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.

What is the breaking capacity of the 5SL4150-7?

10 kA per both EN 60898 and IEC 60947-2 at 400 V AC, with overvoltage category III.

Does the 5SL4150-7 drop into a panel specified for the 5SL6016-7KL?

Both are 1-pole SENTRON MCBs on the same DIN-rail footprint (18 mm width), but the 5SL4150-7 is a 50 A C-curve while the 5SL6016-7KL is a different rating and characteristic. Verify the load and coordination requirements before substituting.
