DC1000V 320A Molded Case Circuit Breaker

GreenWatt adheres to the principle of "quality first" and has accumulated nearly 30 years of experience in product development and production testing. Whether for industrial power distribution projects or the expansion of new energy systems, the DC1000V 320A molded case circuit breaker can be used as a core protection component.

Product Details

I. Structural Design for High-Voltage DC Systems

The GreenWatt DC1000V 320A molded case circuit breaker is specifically designed for high-voltage DC environments. Compared to ordinary low-voltage circuit breakers, it features a higher insulation class and stronger arc-extinguishing capability.

1. High Breaking Capacity 20KA In the event of a short circuit, the 20KA breaking capacity can interrupt the current in a very short time, reducing the impact on equipment and lines.

2. DC-Specific Arc-Extinguishing Structure

Optimized arc-extinguishing chamber design extends the arc path and improves arc cooling efficiency, suitable for 1000V DC system applications.

3. Clear Status Indication

The panel features clear ON/OFF position markings, allowing on-site maintenance personnel to quickly determine the operating status.

II. Core Technological Advantages

■ Flame-Retardant Housing Material

The flame-retardant engineering plastic housing reduces the risk of fire inside the electrical cabinet, suitable for industrial and commercial environments.

■ High-Purity Copper Conductor Structure

Key internal conductive components use high-purity copper, reducing contact resistance and minimizing heat generation and energy loss. In long-term operation, it can help users reduce system operating costs.

■ Wide Voltage and Current Coverage

This DC1000V 320A molded case circuit breaker is suitable for various DC system scenarios, such as:

Industrial DC power distribution

Photovoltaic DC combiner

Energy storage battery systems

DC charging equipment

When expanding photovoltaic systems, if the current remains within the range, it can continue to be used without changing the model.

Application Scenarios

1. Industrial DC Power Distribution Systems

In factory DC bus systems, the DC1000V 320A molded case circuit breaker can serve as the main protective switch.

2. DC Side of Photovoltaic Power Plants

Suitable for protection between photovoltaic arrays and inverters.

3. Energy Storage and Battery Systems

Installed at the battery output or within energy storage cabinets to ensure DC circuit safety.

FAQ (Frequently Asked Questions)

Q: Can this DC1000V 320A molded case circuit breaker be used in outdoor electrical cabinets?

A: Yes, but the electrical cabinet must be waterproof (IP54 or higher). The DC MCCB itself is not fully waterproof, so it needs protection from rain or moisture.

Q: How do I reset the breaker after it trips?

A: First, fix the issue that caused the trip (like an overload or short circuit). Then, push the switch from the “off” position to the “on” position firmly—it will click to confirm reset.

Q: Does it work with AC systems?

A: No, this is a DC MCCB. Using it with AC voltage will damage the product and cause safety risks.
