Why it Matters

C-Curve for General Circuits
The C-curve trips between 5 and 10 times rated current, giving it the headroom to ride out normal inrush from mixed lighting and small-motor loads without nuisance tripping, while still clearing genuine faults quickly. It's the go-to characteristic for the majority of general-purpose final sub-circuits in Australian boards.

Fast Busbar Installation
Compatible with the MAX9 18mm-pitch pin-type busbar, this MCB can be fed without individual cable tails between devices, cutting board build time and giving a cleaner, more serviceable finish. Line connection can be taken from the top or bottom for install flexibility.

Built Tough and Built to Last
Rated to 20,000 mechanical and 10,000 electrical operations, with an operating range of -25°C to 70°C (derating applies), the MX9MC125 is made for the temperature swings of real Australian switchboards.

Is the MX9MC125 a single-pole breaker?
Yes. It is a 1-pole (1P) MCB occupying a single 18mm module on the DIN rail, protecting one active conductor.

What does the C curve mean on this MCB?
C-curve means the breaker trips magnetically at 5 to 10 times its 25A rating, making it suitable for general circuits with moderate inrush such as lighting and power outlets.

What is the breaking capacity of the MX9MC125?
It has a rated short-circuit breaking capacity of 6000A (6kA), tested to AS/NZS 60898 for use in residential and commercial switchboards.
