DC1500V 500A Molded Case Circuit Breaker

GREENWATT, a professional manufacturer of DC1500V MCCBs, provides reliable DC1500V 500A molded case circuit breakers for commercial DC systems such as industrial and commercial energy storage, ground-mounted photovoltaic power stations, or DC lighting grids. This DC1500V 500A molded case circuit breaker features a compact 2P (2 poles) design, effectively saving installation space within electrical cabinets, and is equipped with user-friendly operating switches for easy daily maintenance.

Technologies and Technical Features

In high-voltage direct current (HVDC) applications, extinguishing an electric arc is far more difficult than with alternating current. Our DC1500V 500A molded case circuit breaker is deeply optimized to address this challenge.

1. Arc Extinguishing Technology Adapted to High-Voltage Environments

This DC1500V 500A molded case circuit breaker integrates a narrow-slot arc extinguishing chamber and magnetic blowout technology. When the current reaches 500A and arcs under high voltage, the circuit breaker can rapidly elongate and cool the arc, ensuring safe circuit disconnection in a very short time, protecting downstream inverters or battery packs.

2. Compact 2P Structure Design

To meet the space density requirements of modern electrical cabinets, we have optimized the internal inter-pole insulation design. Even at high voltage levels of DC1500V, this product maintains a compact form factor, providing users with more layout possibilities within limited commercial energy storage container space.

3. Durability and Ease of Operation

Contact System: Utilizes a high-conductivity alloy material to ensure low contact resistance during long-term operation at 500A.

Operating Handle: Ergonomically designed with clear indicators (ON/OFF/TRIP) and supports a padlock function for safe maintenance.

Housing Material: Constructed with high-grade flame-retardant reinforced materials, possessing excellent resistance to tracking and mechanical strength.
