Tesla RCDM132-4.5kA Mini RCBO Safety Switch 32 Amp 1 Pole 4.5kA Type A 30mA 240V Electronic

Description

Serious 32 amp protection in one module.

A 32 amp final subcircuit needs overload and short-circuit protection plus earth leakage protection. The Tesla RCDM132-4.5kA delivers both in a single 18mm module, freeing the board space a separate breaker and RCD pair would otherwise occupy.

Why a 32 Amp RCBO Earns Its Space

One module, two jobs. An RCBO is a residual current device and a miniature circuit breaker in one body. The MCB half opens on overload and short circuit; the RCD half opens on earth leakage above 30 mA. Running both functions through one device means a fault on this circuit trips only this circuit, rather than dropping every load sitting behind a shared RCD. On a board where every 18mm of DIN rail is spoken for, that is the difference between fitting the job in and rebuilding the board.

Type A detection at 30 mA. Type A residual current detection responds to AC residual currents and to pulsating DC residual currents. Modern 240V loads increasingly contain switch-mode power supplies and electronic control gear, and the leakage those produce is not always a clean sine wave. A Type A device is built to see it. The 30 mA rated residual operating current is the level used for personal protection on Australian final subcircuits.

The 1P+N footprint. The RCDM132-4.5kA is 18mm wide in the 1P+N format, the same footprint as a standard single pole circuit breaker. Adding residual current protection to a 32 amp circuit therefore does not force a wider enclosure or a second row of DIN rail. On retrofit and board upgrade work the available module count is often the deciding constraint, and a device that combines both protective functions inside 18mm removes it.

Built to sit in an Australian board. The RCDM132-4.5kA clips to standard 35mm DIN rail and complies with AS/NZS 61009.1:2015, carrying SAA Approval and ESV compliance. The 4.5 kA breaking capacity suits domestic and light commercial boards where the available prospective fault current is within that figure. Rated at 240V AC and 50/60Hz, it is an electronic type device with a clear On/Off indicator so a tripped state is visible at a glance during fault finding. It is supplied in boxes of 10 and cartons of 100, which suits switchboard builders and electrical contractors buying in volume rather than one device at a time.

Is the Tesla RCDM132-4.5kA a Type A RCBO?
Yes. It is specified as Type A with a 30 mA residual rated current, so it detects both AC and pulsating DC residual currents rather than AC only.

What does the 4.5 kA figure on this RCBO mean?
It is the breaking capacity, the maximum prospective short-circuit current the device is rated to interrupt safely. Confirm the prospective fault current at your board is within 4.5 kA before selecting it.

How much switchboard space does the RCDM132-4.5kA take?
It is 18mm wide, a single module, and mounts on standard 35mm DIN rail, so it occupies the same space as an ordinary single pole circuit breaker.
