The famous Clipsal RCD (also known as ‘Safety Switch’) is an absolute must for every home. In fact, it is a legal requirement for all new homes in Australia to have RCD protection for all final sub-circuits. Why? Because in the case of faulty appliances or wiring, this little device in your switchboard will help to disconnect power and help to save your loved ones from a potentially fatal electric shock.

Electrical cables can get extremely hot due to overload and short circuits and potentially damage your home due to electrical fires.
To help protect cables from damage, you need to have MCB installed at the switchboard.
Instead of having a separate MCB and RCD for each circuit, make the smart choice with Clipsal SLIM RCBO. This is a combo device that will provide RCD & MCB functions in 1 device and save valuable space in your switchboard.

The Clipsal MX9R1120 product is a residual current breaker with overcurrent protection (RCBO).
The MX9R1120 is a 1P+N circuit breaker with 1 protected pole, 20A In rated current at 30øC and C tripping curve.

Features and benefits:

• 10mA 
• Top and bottom line and load compatible for ease of installation.
• Short circuit breaking capacity of 6kA.
• Rated at 240V, 10mA, type A, C-Curve.
• One module width – ideal for retrofit installations where space is limited.
