        Schneider Electric A9F44340 | Acti9 iC60N 40A MCB 3P C Curve | 6kA

        The Schneider Electric A9F44340 is a 40A three pole circuit breaker from the Acti9 iC60N Disbo range. It protects a three phase circuit against overload and short circuit, and all three phases trip together. The A9F44340 has a C curve and is rated 6000A Icn at 400V AC to EN/IEC 60898-1. It clips onto DIN rail and takes up three modules.

        A 40A three phase circuit feeds sub-boards and larger fixed plant, and the board it sits in is not always in a cool switchroom. Plant rooms, rooftop enclosures and sheds run hot through summer, and coastal and tropical sites add humidity on top. The A9F44340 is rated to operate from -35 to 70 degrees Celsius and at 95 percent humidity at 55 degrees, with tropicalisation class 2 treatment to IEC 60068-1.

        The A9F44340 is three modules wide, so it fits a standard three phase way on the rail. Mechanical endurance is 20000 operating cycles against 10000 electrical, which covers a circuit switched regularly for servicing. The handle padlocks and takes a seal in the off position.

        Features

        • 40A across all three phases — sized for three phase sub-mains and larger fixed plant.
        • One trip takes out all three phases — a fault on any phase disconnects the lot, so nothing downstream is left live.
        • C curve — the magnetic trip sits at 8 times rated current, around 320A here, which is the curve used where motors and compressors are on the circuit.
        • 6kA short circuit rating — 6000A at 400V AC, the headline rating under EN/IEC 60898-1.
        • 10kA ultimate, 7.5kA in service — under EN/IEC 60947-2 it breaks 10kA once (Icu), and 7.5kA while staying fit for continued use (Ics).
        • Works on AC or DC — rated to 440V AC and 180V DC.
        • Takes up to 35mm² cable — one terminal top or bottom, 35mm² rigid or 25mm² flexible, torqued to 3.5 N.m.
        • Padlocks off — the handle takes a padlock, or a 0.7mm sealing wire, in either the off or on position.
        • Built for hot, humid boards — operates from -35 to 70 degrees Celsius and handles 95 percent humidity at 55 degrees.
        • Limits let-through energy — class 3 under EN/IEC 60898-1, the highest of the three, so less fault energy reaches the cable downstream.
        • No earth leakage protection — overload and short circuit only. Residual current protection comes from a separate block.
        • IP20, so it lives in a board — finger-protected but not sealed against dust or water.

        Where to use

        • Three phase sub-main feeds — 40A protection upstream of a workshop, shed or tenancy board.
        • Plant room and rooftop boards — enclosures that run hot through summer.
        • Humid and coastal installations — sites where tropicalisation class 2 treatment is called for.
        • Ducted air conditioning — three phase packaged and condensing units.
        • Compressors and chillers — three phase compressor sets started direct on line.
        • Control panels and machine builds — DIN rail mounting on panels built to fixed module widths.
        • Switchboard upgrades and rewires — a clip-on replacement for an existing 40A three phase C curve device.

        The A9F44340 is not a residual current device and provides no earth leakage protection on its own. It is rated IP20, so installation must be inside a switchboard or enclosure, and the breaker is not suitable for exposed or wet positions. Rated voltage stops at 440V AC and 180V DC, so the device must not be fitted above those limits.

        (A9F44340)

        The A9F44340 protects a three phase circuit against overload and short circuit. A bimetallic element trips on sustained overcurrent, and a solenoid trips within milliseconds on a fault. All three poles open together, and the toggle is reset by hand once the fault is cleared.

        The breaker conforms to EN/IEC 60898-1 and EN/IEC 60947-2. Rated short-circuit capacity is 6000A Icn at 400V AC under 60898-1, and 10kA Icu at 380 to 415V AC under 60947-2. Utilisation category is A, rated insulation voltage 500V AC, impulse withstand 6kV.

        Installation or replacement inside a switchboard must be carried out by a licensed electrician under AS/NZS 3000. The breaker clips onto DIN rail without tools. Terminals are tightened to 3.5 N.m with 14mm of insulation stripped from the conductor.

        One terminal top or bottom, taking 1 to 35mm2 rigid or 1 to 25mm2 flexible. Wire stripping length is 14mm for a top or bottom connection. Tightening torque is 3.5 N.m top or bottom.         

        The handle is padlockable, and sealable with 0.7mm cable diameter in the off or on position. A contact position indicator and a trip indicator are fitted, and control type is a toggle.

        Earth leakage protection is listed as a separate block, so it is not built into the breaker. Protection covers overload and short circuit only.
