Product details

Rated 25 A at 240 V AC with a 6 kA breaking capacity per EN 60898 (and matching 6 kA per IEC 60947-2), it fits residential, commercial, and light-industrial panels where the prospective short-circuit current stays under 6 kA.

Physical fit and mounting

This is a 1P+N (single-pole switched neutral) MCB occupying 2 modular width units (18 mm each) on a DIN rail. Touch protection is built in per the product feature. Sealable terminals allow the panel builder to lock the cover after commissioning.

Vibration resistance is rated at 50 m/s² from 25 to 150 Hz and 60 m/s² from 10 to 150 Hz per IEC 60068-2-6 — acceptable for most industrial panels but not for direct mounting on high-vibration machinery without additional damping.

Frequently asked questions

What is the breaking capacity of 5SJ6525-7?

6 kA per both EN 60898 and IEC 60947-2, at 240 V AC.

Where can I buy 5SJ6525-7 and get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — no stock or lead-time figures are published here.

Will 5SJ6525-7 drop into a panel specified around 5SJ6220-6?

Both are 2-MW-unit SENTRON 5SJ6 breakers with the same 70 mm depth, DIN-rail mount, and IP20 rating. The key difference is the trip curve: 5SJ6525-7 is C-curve (25 A), while 5SJ6220-6 is B-curve (20 A). If the panel was designed for B-curve coordination, swapping to C-curve may reduce selectivity with upstream devices — verify the coordination study before substituting.
