DC Circuit Breaker 2P 250A – Special for photovoltaic installations & batteries

Static presentation of the digital LCD voltmeter. Compact format, high-definition screen, and neat finishes for a clean installation.

This DC circuit breaker 2 poles 250A is designed for the protection and load disconnection of your high voltage DC circuits: photovoltaic fields, battery banks, inverter input/output, etc.
It ensures a clear and secure disconnection during maintenance operations or in case of a fault in the installation (overload, short circuit).

With a nominal voltage of 550 VDC and an isolation voltage up to 1500 VDC, this circuit breaker meets the requirements of modern PV and energy storage systems. Its robust design and protection rating IP20 make it a reliable device for integration into an electrical cabinet or enclosure.

Main applications

• Protection of photovoltaic strings in direct current
• Cut-off and protection of battery banks (energy storage)
• Securing the connection solar panels / regulator / inverter
• General DC cut-off on solar / battery hybrid installations
• Use as a maintenance isolator on DC circuits up to 250A

Usage tips

For optimal safety, this circuit breaker must be installed by a qualified electrician, in a suitable enclosure or cabinet, respecting the polarity (+/-) and cable sections compatible with the nominal current (250A). It is recommended to place it as close as possible to the DC source (batteries or panels) to limit the length of unprotected cable.
