Product details

The B-curve (3-5 In) means it's a straight pick for resistive and general-purpose loads; don't spec it for motor-starting inrush unless the load is very light.

Fit and footprint

Mounts in any position. IP20 with conductors connected — fine for enclosed panels, not for open washdown zones.

Listed as current production. Compliance stack covers IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 — so it's accepted across European and North American installs. Halogen-free and silicon-free construction, sealable, pollution degree 3 rated.

Frequently asked questions

What is the breaking capacity of 5SY7106-6?

15 kA per EN 60898-1 and 40 kA per IEC 60947-2. At DC per IEC 60947-2 it's rated 15 kA. Under UL 1077 it's 5 kA.

Will 5SY7106-6 drop into a panel specified around 5SY4140-7?

Both are 1-pole SENTRON MCBs on the same DIN-rail footprint, same 18 mm width. The 5SY7106-6 carries a B-curve and higher interrupting ratings (15/40 kA vs the 5SY4140-7's ratings). Check the trip characteristic matches your load before swapping — if the original spec called for a C or D curve, the B-curve may nuisance-trip on inrush.

Where can I buy 5SY7106-6 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
