1500V 2P DC 300A 400A Molded Case Circuit Breaker for Solar PV Systems

Protect your solar PV or other DC power line against overcurrent and short circuits with the TOMZN TOM7Z molded case circuit breaker. Its non-polarized design accepts input from the top or bottom, giving you more flexibility when planning a compatible DC installation.

Use it in a photovoltaic system or consider it for wind, hydropower, electric vehicle, and other DC power supply applications. Check that the breaker’s voltage and current ratings suit your system before installation.

Benefits & Tips

• Flexible connection direction: The non-polarized design operates with input from either the top or bottom.
• Two protection functions: Overcurrent and short-circuit protection help protect DC power lines.
• System planning: Compare the listed voltage, current, and breaking capacity with your application requirements.
