3-pole 25A 660Vdc MCB circuit breaker for protection against short circuits and overloads in both domestic and industrial DC direct current applications.
The main application of this type of thermal-magnetic switch is the protection of renewable energy installations in direct current, service voltage of 660Vdc , as well as in photovoltaic systems, solar pumping systems, battery systems, electric vehicle charging systems, etc. In solar panel systems it allows to isolate or disconnect the strings of photovoltaic modules connected to an inverter.
Rated Breaking capacity 6000A (6kA) according to EN 60898-2 and 10000A (10kA) EN 60947-2. Equipped with a green/red status indicator and a transparent cover for placing an indicative label. The advantage of using them over fuses is the possibility of quick and safe resetting in the event of short circuits or power cuts.
Highly reliable and high-performance device, allowing a high number of work cycles. Its selection must be made based on the application, taking into account the nominal current and the system voltage.
