Why it Matters

Icn Equals Ics at 10kA
Many breakers quote a headline breaking capacity the device can interrupt once, then quietly derate what it can handle repeatedly. On this range Tesla states Icn = Ics = 10kA, meaning the rated ultimate and rated service breaking capacities are the same figure. In practice the breaker is specified to remain serviceable after clearing a fault at its full rating, rather than being a one-shot device at the headline number. Where fault levels are high, that equivalence is worth checking on any datasheet before you specify.

Energy Limiting Class 3
Class 3 is the highest energy limiting classification under the MCB standards. It describes how effectively the device restricts let-through energy during a short circuit, cutting the current before it reaches its prospective peak. The practical benefit is less thermal and magnetic stress on the downstream cable and connected equipment in the milliseconds before the fault clears.

Three Jobs in One Device
Tesla specifies this range for protection against overload, protection against short circuit, and a function of isolation. The overload element handles sustained currents above rating, the magnetic element deals with short circuits, and the isolation function means the breaker provides a defined open point for safe work downstream. Contact position indication supports that last role by showing whether the contacts have genuinely opened, not merely whether the toggle has moved.

C Curve for General Circuits
The C curve sits between the sensitive B curve and the high-inrush D curve. It tolerates moderate starting surges without nuisance tripping while still protecting the circuit, which makes it the practical default for mixed loads on a general distribution board. At 10A the device suits lighting and small power circuits where a modest inrush is expected. Matching curve to load avoids the two familiar failure modes: a breaker that trips every time something starts, or one too slow to protect the cable.

Flexible Mounting
The range mounts on DIN rail or chassis, so it suits standard modular enclosures and custom panel builds alike. That flexibility is useful when a board is assembled around existing hardware rather than a purpose-built load centre.

Part of a Full Range
Tesla builds this 10kA range in 1, 2 and 3 pole versions from 6A through to 63A, all sharing the same breaking capacity and Class 3 energy limiting. Specifying across one range keeps a board consistent in appearance and behaviour, and simplifies carrying spares.

What is the breaking capacity of the MCB10K1P10?
It is rated 10kA, with Icn equal to Ics, and carries Energy Limiting Class 3.

Does this circuit breaker provide isolation?
Yes. Tesla specifies a function of isolation alongside overload and short circuit protection, and the device has contact position indication.

Can it be mounted on a chassis rather than DIN rail?
Yes. The range is specified for both DIN and chassis mount.
