Schneider Electric A9F85340 is an Acti9 iC60H miniature circuit breaker designed for reliable distribution and branch circuit protection in AC and DC installations. This 3‑pole, 40 A device features a D‑curve thermal‑magnetic trip characteristic, making it well suited to circuits with higher inrush currents such as motors, transformers and industrial control loads. It provides high short‑circuit performance, including 10 kA breaking capacity at 440 V AC (IEC/EN 60947‑2) and 10,000 A at 400 V AC (IEC/EN 60898‑1), with a clear toggle actuator, contact position indication and local trip indication for straightforward status checking.
The A9F85340 mounts to a standard DIN rail and is compatible with comb busbars/distribution blocks from either top or bottom. It occupies 6 x 9 mm pitches (54 mm wide) and measures 85 x 54 x 78.5 mm, with IP20 protection. Connections are via single terminals (top or bottom) accepting 1…35 mm² rigid or 1…25 mm² flexible conductors, with a 14 mm strip length and 3.5 N·m tightening torque.

What type of protective device is this?
It is a miniature circuit breaker (MCB) designed for distribution circuits, using a thermal-magnetic trip mechanism to protect against overloads and short circuits.
How many poles does it have and what does that mean in practice?
It is a 3-pole device (3P), intended to switch and protect three live conductors together, which is typical for three-phase circuits.
What is the rated current?
The rated current is 40 A (In = 40 A).
What trip curve does it use, and when is it typically chosen?
It uses a D curve, which is commonly selected for circuits with higher inrush currents (for example, loads that can draw a brief surge on start-up).
What is the magnetic tripping threshold for this breaker?
The magnetic tripping limit is 12 × In ± 20%, which equates to approximately ``12 × 40 A = 480 A`` (with tolerance).
What is the short-circuit breaking capacity at 400 V AC?
It is rated at 10,000 A (10 kA) Icn at 400 V AC 50/60 Hz in accordance with EN/IEC 60898-1.
What are the breaking capacities under EN/IEC 60947-2 at common system voltages?
Typical Icu ratings include 10 kA at 440 V AC, 15 kA at 380–415 V AC, and 30 kA at 220–240 V AC (EN/IEC 60947-2).
Can it be used on DC circuits?
Yes. It is specified for both AC and DC networks, with an Icu of 15 kA at up to 180 V DC (EN/IEC 60947-2).
What is the rated insulation voltage and impulse withstand voltage?
The rated insulation voltage (Ui) is 500 V AC, and the rated impulse withstand voltage (Uimp) is 6 kV.
How is it mounted in a panel?
It is designed for fixed mounting on a DIN rail.
What are the physical dimensions and module width?
Overall dimensions are 85 mm (H) × 54 mm (W) × 78.5 mm (D). The width corresponds to 6 modules of 9 mm pitch.
What conductor sizes can be terminated on the terminals?
It accepts single conductors at the top or bottom: 1–35 mm² rigid and 1–25 mm² flexible.
What tightening torque and strip length are recommended for the terminals?
Recommended tightening torque is 3.5 N·m, and the strip length is 14 mm for top or bottom connection.
Does it provide any status indication?
Yes. It includes a contact position indicator and a local trip indicator, with a toggle actuator for manual operation.
Is earth-leakage (RCD) protection built in?
No. Earth-leakage protection is provided via a separate block. If you need residual-current protection, it is typically added as an additional module rather than being integrated into this MCB (e.g., Schneider A9F85340 is specified with separate earth-leakage protection).
What environmental conditions is it specified for?
It is rated IP20, with an operating ambient temperature range of -35 to 70 °C, storage range of -40 to 85 °C, and operating altitude of 0 to 2000 m.
