The CHCYZO 200A DC Circuit Breaker MCB 1P is a durable and high-performance protection device designed for LiFePO4 batteries, solar power systems, DC charging setups, and battery-based energy storage solutions. Engineered to safely handle up to 200A and 125V DC, this compact 1-pole breaker provides reliable short-circuit and overload protection while functioning as a convenient On/Off isolation switch. Its robust construction and long mechanical life make it ideal for electric vehicles, battery banks, solar charge controllers, inverters, and DC distribution boxes in Bangladesh.

Features:

• Designed for LiFePO4 batteries, electric vehicles, battery-powered systems, solar DC systems and energy storage applications.

• Type B tripping characteristic (3–5× rated current) for precise protection of sensitive and inductive DC loads.

• Rated for 200A continuous current and 125V DC working voltage.

• Acts as both a circuit breaker and an On/Off switch for manual power isolation.

• Single-pole (1P) compact structure for space-saving installations.

• Suitable for high-current battery pack protection and DC busbars.

• Long mechanical operating life of over 10,000 cycles for durability.

• High electrical endurance with 4,000+ switching operations.

• DIN rail mounting compatible with standard electrical enclosures.

• Supports use in EVs, battery cars, solar setups, DC distribution and industrial control systems.

• Stable performance with high breaking capacity suitable for high-current DC circuits.

• Designed for stable operation within –5°C to +40°C ambient temperature range.

• Quality components with CE and RoHS compliance (if applicable).

How to Use:

• Install the breaker on a standard DIN rail inside a DC distribution panel or battery protection enclosure.

• Connect the input side to the battery or DC source and the output side to the load or inverter.

• Ensure correct polarity when wiring in DC applications for optimal safety.

• Use the lever switch to manually turn power On or Off during maintenance or emergency isolation.

• For LiFePO4 battery systems, place the breaker between the battery pack and inverter/charger for short-circuit and overload protection.

• Periodically inspect the terminals to ensure tight connections for high-current operation.

• Use appropriate cable thickness rated for 200A to prevent overheating.

• Avoid exceeding the rated voltage and current to maintain long-term reliability.

• Store and operate the device within the recommended temperature range.

Product Instructions:

• Shut off all power before installation to avoid electrical hazards.

• Mount the breaker vertically or horizontally according to the panel design.

• Avoid moisture, dust and direct sunlight exposure to ensure long-term performance.

• Verify load requirements before connecting to make sure they are within 200A at 125V DC.

• Use proper torque when tightening screws to prevent loosening during high-current use.

• Replace the device if any signs of overheating, burning smell or mechanical wear appear.

• Follow standard electrical safety guidelines while working with DC high-current systems.
