Product details

The Siemens SENTRON 5SP4192-7 is a 1-pole miniature circuit breaker rated 125 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898 at 230/400 V AC.

Mounts on DIN rail or via screw fixing in any orientation. Occupies 1.5 modular width units (27 mm wide) with a 70 mm installation depth; the overall depth is 76 mm. Tunnel terminals top and bottom accept copper conductors. The IP20 rating applies with connected conductors; the handle area reaches IP40 when a distribution cover is fitted. Degree of pollution 3 and overvoltage category 3 suit it for fixed-installation distribution boards in industrial environments. Sealable, halogen-free, silicon-free.

Withstands shock at 150 m/s² (11 ms half-sine) per IEC 60068-2-27 and vibration at 50 m/s² (25–150 Hz) and 60 m/s² at 35 Hz per IEC 60068-2-6. Maximum 95% relative humidity.

Frequently asked questions

Where can I buy 5SP4192-7 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 quote time.

What is 5SP4192-7's breaking capacity?

The breaking capacity is 10 kA per EN 60898 at 230/400 V AC.

What is the tripping characteristic of 5SP4192-7?

It has a C tripping characteristic, meaning it trips at 5 to 10 times rated current, suited for moderate inrush loads.

Will 5SP4192-7 drop into a panel specified around 5SP4292-7 without rewiring?

Both are 1-pole SENTRON 5SP4 series MCBs with the same 27 mm width per 1.5 modular units, same DIN-rail mounting, and tunnel terminals. The 5SP4192-7 is a 125 A C-curve; the 5SP4292-7 is a different rating. Check the specific rating and curve of the 5SP4292-7 in your BOM before swapping — the mechanical fit is identical, but the protective function may differ.
