Product features

Designed to offer dependable protection for electrical distribution systems, the Schneider A9F29450 is a premium miniature circuit breaker (MCB) from Schneider Electric's reputable Acti 9 iC65H series. With a D-curve trip characteristic and a 50A rated current (at 30°C), this 4P (four-pole) circuit breaker is excellent at protecting wiring and equipment from overloads and short circuits, particularly for loads like transformers and motors that draw high inrush currents. This robust gadget is a great option for both commercial and industrial electrical projects because it combines robust performance with user-friendly features.

With a rated working voltage of 400V AC (50/60Hz) and a rated insulation voltage of 500V AC, the Schneider A9F29450 exhibits remarkable electrical performance. It can safely stop fault currents in a variety of power systems thanks to its outstanding breaking capacity, which is 20kA at 220-240V AC, 42kA at 12-133V AC, 15kA at 380-415V AC, and 10kA at 440V AC. Sensitive equipment is protected while system stability is maintained thanks to the D-curve magnetic trip feature (10–14×In), which enables it to withstand brief surge currents without needless tripping. It also has an IEC 60947-2-compliant isolation function, which provides an additional degree of security during maintenance.

The Schneider A9F29450 is physically made for long-term use and simple installation. It is appropriate for crowded electrical panels due to its small size (72 x 94 x 78.5 mm) and 0.5 kg weight. It uses DIN rail mounting with a locking clip for secure fixation. Its IP20 protection rating keeps solid objects bigger than 12mm out, and its pollution level 3 rating guarantees dependable performance in challenging conditions. The gadget has a robust handle for manual control, a clear on/off position indicator, and a mechanical and electrical lifespan of 20,000 and 10,000, respectively.

Application scenarios

Schneider A9F29450 is essential for safeguarding production line machinery in manufacturing facilities, including transformers, small motors, and conveyor belts. The Schneider A9F29450's D-curve trip feature (10-14×In magnetic trip) allows it to withstand these brief surges without needless tripping, guaranteeing continuous production process operation. These machines frequently draw high inrush currents when starting up. Its strong breaking capacity (up to 42kA at 12-133V AC) and rated working voltage of 400V AC allow it to safely interrupt fault currents during overloads or short circuits, preventing damage to costly industrial machinery and minimizing downtime.

Schneider A9F29450 is also very beneficial for commercial buildings such as hotels, office towers, and shopping centers. These areas have intricate electrical systems that run retail equipment, air conditioners, elevators, and lighting, all of which require dependable protection. The Schneider A9F29450's IP20 protection rating shields it from dust and small debris, and its small size (72 x 94 x 78.5 mm) makes it simple to install in crowded electrical panels. Its isolation function, which satisfies IEC 60947-2 standards, also makes maintenance easier by enabling electricians to safely work on individual system components without interfering with the building's power supply.

FAQ

Q: What is the Schneider Electric A9F29450?

A: A 4-pole (4P) miniature circuit breaker (MCB) from the Acti9 iC65H series is the Schneider Electric A9F29450. It is intended to shield electrical circuits in low-voltage distribution systems from harm brought on by overcurrent and short circuits. This specific model is appropriate for applications with high inrush currents because it has a D-type trip characteristic and a 50 A rated current.

Q: What does the "D-type" trip characteristic mean on this MCB?

A: This circuit breaker's D-type trip characteristic shows that it can tolerate brief high inrush currents without experiencing annoying tripping. Circuits powering devices with high starting currents, like motors, transformers, or specific kinds of lighting, are usually utilized. Because of this, the A9F29450 with D-curve is perfect for safeguarding circuits in commercial and industrial settings where these kinds of loads are typical.

Q: What is the difference between the A9F29450 and other Acti9 iC65 models?

A: Within the Acti9 series, the model number A9F29450 is a particular product code. For parts like the iC65 MCBs, the "A9F" prefix serves as a product number identifier. Different specifications, such as the number of poles, rated current, and trip curve, are represented by variations in this code. For instance, the A9F29450 is distinguished by its D-type trip characteristic, 50A rating, and 4-pole design.
