CHINT High Quality Circuit Breaker Original

7-Day Replacement Warranty for complete peace of mind

The CHINT NXB-63 MCB series is designed to provide dependable protection for electrical circuits in homes, offices, and industrial environments. With advanced technology, durable construction, and global trust in the CHINT brand, these breakers safeguard your system against overloads and short circuits while maintaining stable performance.

This series is available in Single Pole (1P), Double Pole (2P), Triple Pole (3P), and Four Pole (4P) variants, making it suitable for a wide range of applications.

Single Pole (1P) – Focused Protection

The Single Pole (1P) MCB is designed to protect one live (phase) wire in a circuit. It is most commonly used in:

• Homes and offices for lighting and socket circuits
• Small appliances and equipment
• Individual line protection in distribution boards

👉 Why choose 1P?

• Compact and cost-effective
• Protects against overload and short circuit on a single phase
• Ideal for small and medium electrical loads

Double Pole (2P) – Enhanced Safety for Single-Phase Systems

The Double Pole (2P) MCB provides protection for both the phase and neutral wires simultaneously. This ensures extra safety, especially in single-phase systems where both conductors need secure isolation.

Applications:

• Single-phase power supply systems in homes and offices
• Small machinery and equipment requiring higher safety
• Distribution boards where neutral protection is also essential

👉 Why choose 2P?

• Disconnects both live and neutral in fault conditions
• Reduces chances of accidental electric shock
• Offers more comprehensive protection than 1P

Triple Pole (3P) – Industrial-Grade Protection for Three-Phase Loads

The Triple Pole (3P) MCB is built for three-phase electrical systems, commonly found in industrial and commercial setups. It protects all three live wires (phases) simultaneously.

Applications:

• Three-phase motors and machinery
• Commercial and industrial distribution panels
• HVAC systems, elevators, and heavy-duty equipment

👉 Why choose 3P?

• Protects all three phases at once
• Prevents damage to motors and equipment from phase faults
• Essential for stable operation in industrial setups

Four Pole (4P) – Maximum Protection with Neutral Safety

The Four Pole (4P) MCB extends the protection of the 3P breaker by also including the neutral line, making it the safest option for three-phase systems with neutral.

Applications:

• Three-phase four-wire distribution systems
• Industrial panels requiring neutral disconnection
• Sensitive equipment setups (IT, data centers, laboratories)

👉 Why choose 4P?

• Offers full isolation of all phases and neutral
• Prevents leakage and neutral faults
• Provides the highest level of safety in demanding environments
