The Schneider 24440 is a four-pole Acti9 iK60N miniature circuit breaker designed for AC electrical distribution applications. Rated at 40 A, it uses a C-curve thermal-magnetic trip mechanism and provides a 6 kA breaking capacity at 400 V AC. The breaker clips onto a standard DIN rail and occupies eight 9 mm modules. It features ON/OFF position indication, IP20 protection and tunnel terminals for rigid or flexible conductors. Its compact construction makes it suitable for protecting multi-phase circuits against overloads and short circuits in electrical distribution panels.

What type of electrical device is this?
This is a Schneider Acti9 iK60N miniature circuit breaker designed to protect AC distribution circuits against overloads and short circuits.
What is the rated current?
The circuit breaker has a rated current of 40 A at an ambient reference temperature of 30°C.
How many poles does the circuit breaker have?
It is a four-pole circuit breaker, with protection provided across all four poles.
What does the C tripping curve indicate?
The C curve provides magnetic tripping at approximately five to ten times the rated current. It is commonly used for circuits with moderate starting currents, including many industrial and commercial loads.
What is the rated breaking capacity?
The rated short-circuit breaking capacity is 6,000 A at 400 V AC, 50/60 Hz, in accordance with EN/IEC 60898-1.
Which electrical networks can it be used with?
The device is intended for AC electrical distribution networks operating at 50 or 60 Hz.
Does it provide earth-leakage protection?
No. This miniature circuit breaker provides overload and short-circuit protection but does not include earth-leakage protection. A separate residual-current device may be required where that function is needed.
How is the device mounted?
The breaker uses a clip-on mounting arrangement for installation on a standard DIN rail.
How much panel space does it require?
The unit is 72 mm wide and occupies eight 9 mm modular pitches. Its overall dimensions are approximately 85 mm high, 72 mm wide and 78.5 mm deep.
What conductor sizes can be connected?
The tunnel terminals accept rigid conductors from 1 to 35 mm² and flexible conductors from 1 to 25 mm². The specified wire stripping length is 14 mm.
What terminal tightening torque is specified?
The recommended tightening torque for the upper or lower terminals is 3.5 N·m.
What are the permitted operating temperatures?
The specified ambient operating temperature range is -25°C to 60°C. The storage temperature range is -40°C to 85°C.
What ingress protection rating does it have?
The device has an IP20 protection rating in accordance with IEC 60529.
Can it be used as an isolating device?
Yes. The circuit breaker is suitable for isolation in accordance with EN/IEC 60898-1 when correctly selected and installed.
What are its mechanical and electrical endurance ratings?
The device is rated for 20,000 mechanical operating cycles and 10,000 electrical operating cycles under the specified conditions.
Does it show whether the contacts are open or closed?
The front toggle provides local ON and OFF indication. However, the device does not include a separate positive contact-position indicator.
