Tesla LNL35C10 RCD/MCB Safety Switch RCBO 10 Amp 3P+N 10kA A Type C Curve 3 Module 415V

Description

High fault levels. Shallow panels. Sorted.

Boards sitting close to the supply transformer see prospective fault currents that outrun a standard safety switch, and switchboard depth is often the constraint that decides what fits. The Tesla LNL35C10 answers both with a 10 kA rated 3P+N RCBO only 54mm deep.

Why it Matters

A 10 kA device for high fault level boards
Breaking capacity is the figure that determines whether a device can clear a short circuit safely or fail trying. This RCBO is rated at 10 kA, which is the figure to check against the prospective fault current calculated for the board, and it matters most on installations with a large supply transformer nearby or short, heavy supply runs. Energy limiting class 3 describes how much let-through energy reaches the downstream circuit during that clearing operation, and the residual element carries a 2000A making and breaking capacity of its own.

Depth is the constraint that bites
The body measures 54mm deep against the 68mm typical of comparable devices, per Tesla's own figures. On a shallow panel or a flush mount enclosure, that difference decides whether the door closes over the wiring loom or the whole enclosure has to be changed. It also leaves more room behind the device for cable bending radius, which is where crowded boards actually run out of space.

Switched neutral with a flying lead
This is a 3P+N device with a switched neutral, so all four conductors break on a trip rather than the three actives alone. The neutral connects through an 80cm flying lead, giving enough reach to land on a neutral bar anywhere in the panel without a joint. Terminals take cables up to 25mm2, covering the conductor sizes normally run to a three phase submain or final subcircuit at this rating.

Built for the long run
Tesla rates the mechanism at 10,000 electrical operations and 30,000 mechanical operations, and the device is built to IEC/EN AS/NZS 61009-1, IEC 61009-2-2 and AS/NZS 61009.1. The C curve suits circuits with moderate inrush, and 400/415V AC at 50/60Hz matches standard Australian three phase supply.

Does the Tesla LNL35C10 switch the neutral as well as the actives?
Yes. It is a 3P+N device with a switched neutral, and the neutral is landed through an 80cm flying lead rather than a fixed terminal.

What fault level is the LNL35C10 rated for?
It carries a 10 kA breaking capacity with energy limiting class 3, and a residual making and breaking capacity of 2000A.

Will the LNL35 C10 fit a shallow distribution panel?
Its body is 54mm deep, which Tesla notes against the 68mm more common on this device type, and it mounts on standard 35mm DIN rail.
