Why it Matters

Built for Australian switchboards
The MX9MC310 is designed and type-tested for Australian conditions, conforming to AS/NZS 60898 for circuit-breakers used in household and similar installations. RCM-marked and rated for -25°C to +70°C ambient operation (with derating), it handles the full range of Aussie site environments from cool southern winters to hot northern summers.

Simultaneous three-phase protection
As a 3-pole device, all three phases are switched together by a single toggle. If a fault trips the breaker on any pole, all three isolate at once — the correct behaviour for protecting three-phase distribution circuits and keeping downstream equipment safe from single-phasing damage.

Fast, clean installation
The 54 mm three-module footprint drops straight onto standard DIN rail, while compatibility with MAX9 pin-type busbar and MAXBAR distribution shortens the wiring time on final sub-circuits. Combination-head screws accept multiple screwdriver types and the double locking clip makes removal from a busbar straightforward when reconfiguring the board.

Q: What is the MX9MC310 used for?
It is a 3-pole 10A C Curve miniature circuit-breaker designed for distribution circuit protection in a MAX9 switchboard, providing simultaneous overcurrent and short-circuit protection across all three phases of a downstream 3-phase sub-circuit.

Q: What does the C Curve tripping characteristic mean?
The C Curve refers to the magnetic tripping range of 5-10 x In (rated current). This makes C Curve MCBs suitable for general-purpose circuits with moderate inrush currents such as fluorescent lighting, small motors, and mixed residential or commercial loads.

Q: What breaking capacity does the MX9MC310 offer?
It provides 6000A breaking capacity at 415V AC 50/60 Hz, tested to AS/NZS 60898, with a rated service breaking capacity (Ics) of 6000A at 100%.
