The Schneider Electric A9N4P32C Acti 9 MCB xC60 4-Pole 32A C Curve 10000A is a high-performance miniature circuit breaker (MCB) designed for protecting electrical circuits against overloads and short circuits. It is part of Schneider Electric's renowned Acti 9 range, which is known for its reliable, efficient, and safe electrical protection solutions. Here’s a detailed description of its features and benefits:
Key Features:
1. 4-Pole Design
The A9N4P32C is a 4-pole MCB, which means it is designed to protect three-phase electrical systems and the neutral. It simultaneously disconnects all three phases and the neutral in the event of a fault. This ensures comprehensive protection for industrial or commercial applications, especially where neutral protection is required in addition to the phases. The 4-pole design is particularly useful in three-phase electrical systems.
2. 32A Rated Current
This MCB is rated for 32 amps (A), which defines the maximum continuous current it can handle before tripping. It’s suitable for use in circuits where the normal operating current does not exceed 32A, commonly found in lighting systems, motors, or equipment that requires moderate current protection.
3. C Curve
The C Curve tripping characteristic is specifically designed for applications where moderate inrush currents may occur, such as motors, transformers, or lighting systems with a surge at startup. The MCB with a C curve typically trips at 5 to 10 times the rated current, providing protection against short circuits without nuisance tripping during normal start-up conditions.
4. Breaking Capacity: 10000A
The breaking capacity of the A9N4P32C is rated at 10000A (10kA), which indicates the maximum fault current the MCB can safely interrupt without being damaged. This high breaking capacity makes it suitable for installations in areas where potential short circuit fault currents are high, such as industrial and commercial settings with robust electrical infrastructure.
5. Acti 9 Series
This MCB is part of Schneider Electric's Acti 9 series, which is known for its advanced features like enhanced safety, flexibility, and ease of installation. The Acti 9 range is built with sustainability and simplicity in mind, offering high levels of protection while being easy to integrate into existing electrical systems.
6. High-Performance Materials
The A9N4P32C is made from high-quality, durable materials that ensure long-term performance even in demanding environments. The housing is fire-resistant and robust, providing additional protection from mechanical impacts, overheating, and fire hazards.
7. Easy Installation
The Acti 9 MCBs are designed for easy and fast installation on DIN rail systems. It comes with a simple clip-on mechanism that allows for quick attachment to distribution boards or panels. This reduces installation time, especially when working on large-scale projects.
8. Visible Trip Indicator
This MCB includes a trip position indicator that clearly shows whether the circuit breaker has tripped due to a fault. This provides quick visual feedback for electricians and maintenance personnel, ensuring faster troubleshooting and system recovery.
9. Isolation and Protection
In addition to overcurrent protection, the A9N4P32C can function as an isolation device. It isolates the faulty circuit from the rest of the system, ensuring that the entire system is not affected by a single circuit failure. This enhances overall system safety and stability.
10. Global Standards Compliance
The Schneider Electric A9N4P32C Acti 9 MCB complies with several international standards, ensuring high levels of safety, performance, and reliability. It meets IEC/EN 60898-1 and IEC/EN 60947-2 standards, which cover MCBs for residential, commercial, and industrial applications.
