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.","metaTitle":"Siemens 5SL3210-6 SENTRON MCB, 2P B-Curve 10A 4.5kA","metaDescription":"Siemens 5SL3210-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 10 A rated, 4.5 kA breaking capacity per EN 60898.

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.
