Chint NXB-125 2p 100A DC Miniature Circuit Breaker

CHINT 100A 2P DC Breaker – Reliable Protection for DC Power Systems

The CHINT 100A 2-Pole DC Circuit Breaker is specifically designed for direct current (DC) applications, offering reliable protection against overloads and short circuits in solar power systems, battery banks, EV charging stations, and other DC installations. Engineered for safety, durability, and efficiency, this breaker ensures uninterrupted and secure operation of critical DC systems.

Features of CHINT 100A 2P DC Breaker:
Rated Current: 100A: Designed to handle high DC loads safely and efficiently.
2-Pole Configuration: Simultaneous disconnection of positive and negative poles for enhanced safety in DC systems.
High DC Voltage Rating: Typically rated for up to 500V DC (varies by model), ideal for solar PV and battery setups.
Fast Breaking Mechanism: Quickly isolates faulty circuits, reducing the risk of damage or fire.
Arc Extinguishing Design: Specialized arc chute or magnetic blow-out design to handle DC arc interruption effectively.
DIN Rail Mounting: Easy installation in standard enclosures and distribution panels.
Compact Modular Build: Saves space and integrates easily into modular power systems.
Durability: High mechanical and electrical endurance for long-term performance.
Standards Compliance: Conforms to relevant DC safety standards, including IEC 60947-2 (with DC adaptation).

Functions of CHINT 100A 2P DC Breaker:
Overload Protection: Prevents damage from prolonged overcurrent by tripping when the current exceeds the 100A threshold.
Short-Circuit Protection: Instantly disconnects the circuit in the event of a short circuit, preventing equipment damage and potential hazards.
Safe Isolation: Provides a secure method to disconnect DC circuits for maintenance or emergencies.
Dual-Pole Switching: Ensures both lines (positive and negative) are simultaneously interrupted, critical in DC systems to prevent floating voltages.

Applications:
Solar PV installations
Battery storage systems
Electric vehicle charging stations
Telecom and industrial DC systems
Off-grid and hybrid energy setups
