Why it Matters

Built for Australian conditions

The MX9MC225 is designed to operate across a wide ambient range of −25°C to +70°C (with derating), making it suitable for switchboards in hot roof spaces, sheds and exposed plant rooms. It carries the RCM mark and is built to AS/NZS 60898, so it meets the compliance expectations of licensed electricians working to the Wiring Rules.

Fast, flexible installation

Line connection can be taken from either the top or bottom, and the breaker is compatible with the MAX9 18mm pitch pin-type busbar system. Tunnel-type terminals accept up to 25mm² rigid conductors with a 2 N.m tightening torque, and a double locking clip speeds mounting and removal on the DIN rail.

Reliable overload and short-circuit protection

A Type C curve suits circuits with moderate inrush — mixed lighting, power and small motor loads — while the 6kA breaking capacity handles fault currents typical of distribution boards. Endurance is rated at 20,000 mechanical and 10,000 electrical cycles.

Is the MX9MC225 a single or double pole breaker?
It is a 2-pole (double pole) MCB, switching and protecting two poles simultaneously.

What does the Type C curve mean on this breaker?
Type C trips magnetically between 5 and 10 times rated current, suiting circuits with moderate inrush such as combined lighting and power or small motors.

What is the breaking capacity of the MX9MC225?
It has a 6000A (6kA) short-circuit breaking capacity at 415V AC, conforming to AS/NZS 60898.
