Product details

Rated current derates with ambient temperature: 10 A at 30 °C, 9.52 A at 40 °C, 9.2 A at 45 °C, and 8.74 A at 55 °C. If the panel runs warm, size the load side accordingly — the 40 °C figure is the one most panel builders use for a standard enclosure. That's fine for a distribution board that sees infrequent switching; for a motor-starting application that cycles daily, you'd want a contactor ahead of this MCB.

Snaps onto standard DIN rail. Mounting position is unrestricted — horizontal, vertical, upside-down, the thermal-magnetic trip works the same. Sealable design lets you lock the toggle in the ON or OFF position with a padlock hasp — useful for lockout/tagout on a branch circuit without pulling the whole panel cover.

Energy limitation class 3. Halogen-free and silicon-free construction. The manufacturer provides IEC 60898 and IEC 60947-2 breaking capacity ratings on the nameplate; RoHS and REACH declarations are standard with the SENTRON series.

Frequently asked questions

Where can I buy 5SL3210-6 and what is the lead time?

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

What is the depth of 5SL3210-6?

76 mm depth, with an installation depth of 70 mm.

What is the width of 5SL3210-6?

36 mm, which is 2 modular width units on a standard DIN rail.

Will 5SL3210-6 drop into a panel specified around 5SL3340-7CC without rewiring?

Both are 2-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is identical. The difference is the rating and curve — 5SL3340-7CC is a 40 A C-curve, while this is a 10 A B-curve. If the panel was wired for 40 A, dropping in a 10 A breaker will trip on the load. Check the branch circuit rating before swapping.

What compliance documentation does Siemens provide for 5SL3210-6?

The MCB carries IEC 60898 and IEC 60947-2 breaking capacity ratings on the nameplate. RoHS and REACH declarations are standard with the SENTRON series. The product is halogen-free and silicon-free.
