Tesla RCDM110-4.5kA Mini RCBO Safety Switch 10 Amp 1 Pole 4.5kA Type A 30mA 240V Electronic

Description

Earth leakage and overload protection in one module.

The Tesla RCDM110-4.5kA is a 10 amp single pole Mini RCBO that combines residual current and overcurrent protection in a single 18mm module, so one device covers both jobs without consuming two spaces on the DIN rail.

One Module, Two Protection Functions

An RCBO is a residual current device and a miniature circuit breaker built into a single body. The MCB half handles overload and short circuit, tripping at up to a 4.5 kA fault level. The RCD half watches for earth leakage and trips at a residual rated current of 30 mA. The result is that a single circuit gets both forms of protection from one device on the rail, rather than sharing an upstream RCD with every other circuit on the board.

That matters most when something trips. A shared RCD takes down every circuit behind it. A per-circuit RCBO isolates only the faulty run, so the rest of the installation keeps working while the fault is traced. At 18mm the RCDM110-4.5kA occupies the same width as a standard single module breaker, which keeps the pole count manageable when a board is being filled out circuit by circuit.

Type A Sensing and the 30 mA Threshold

This unit is a Type A device. Type A residual current sensing responds to sinusoidal AC residual currents and to pulsating DC residual currents, which is the classification specified where connected equipment contains electronic components rather than purely resistive loads. The 30 mA residual rated current is the level used for additional protection against electric shock under Australian wiring practice.

The device is designated Electronic in the Tesla product data, and carries an On/Off indicator so switch position can be read at a glance during fault finding.

Australian Compliance and Board Fit

The RCDM110-4.5kA complies with AS/NZS 61009.1:2015, the Australian and New Zealand standard for residual current operated circuit breakers with integral overcurrent protection. It carries SAA approval and is listed by Tesla as ESV compliant. Mounting is to standard 35mm DIN rail, and the rated voltage of 240V AC at 50/60Hz matches single phase distribution here.

Supply is in boxes of 10 and cartons of 100, which suits contractors fitting out multiple boards or holding board stock on the van.

Q: How wide is the Tesla RCDM110-4.5kA on the DIN rail?
A: It is 18mm wide, which is a single module. The Tesla product data sheet lists the width as 18mm (1P+N), and it mounts to standard 35mm DIN rail.

Q: What does the 4.5 kA rating on this RCBO mean?
A: 4.5 kA is the rated breaking capacity, meaning the maximum prospective short circuit current the device is rated to interrupt. It is separate from the 10 A rated current of the circuit it protects.

Q: Is the Tesla RCDM110-4.5kA a Type A residual current device?
A: Yes. The product data sheet specifies Type A with a residual rated current of 30 mA, rated at 240V AC and 50/60Hz.
