Product details

The 3P+N configuration switches all three phases and the neutral, with the neutral pole switching but not protecting — common for 3-phase 4-wire distribution in European-style panels. Rated for 400 V AC between phases, this MCB fits 230/400 V TN and TT systems. The 4 MW width (72 mm) occupies four 18 mm DIN-rail positions — standard for a 3P+N breaker in a SENTRON distribution board.

Installation depth is 70 mm, with an overall depth of 76 mm — check your enclosure depth if using a shallow gland plate. Screw terminals accept solid or stranded conductors from 0.75 to 25 mm²; tighten to 2.5 to 3 N·m. The neutral conductor is switched (not just linked), so verify the neutral bar arrangement in your panel — this breaker replaces both the phase and neutral protection in one unit, saving a separate neutral link.

Frequently asked questions

What is the difference between 5SL6616-7YA and 5SL6606-7YA?

The 5SL6606-7YA is the 6 A version of the same 3P+N C-curve MCB. The 5SL6616-7YA is the 16 A variant. Both share the same 6 kA breaking capacity, 400 V rating, and 4 MW footprint — they are drop-in interchangeable in the same panel position, differing only in the thermal trip rating.

What conductor sizes does 5SL6616-7YA accept?

Solid and stranded conductors from 0.75 mm² up to 25 mm². The screw terminals require a tightening torque of 2.5 to 3 N·m.

What is the depth of the 5SL6616-7YA?

Overall depth is 76 mm; installation depth (behind the panel face) is 70 mm. This is standard for a 4 MW SENTRON MCB.
