FAQs for DC Modular Contactor

Here you can find answers to some of your common questions related to dc modular contactors, which can help resolve any doubts you may have.

What makes DC contactors different from AC contactors?
DC contactors require specialized arc extinction technology because DC current doesn't have natural zero-crossing points like AC. Our DC contactors feature magnetic blow-out systems, enhanced contact gaps, and specialized materials to safely interrupt DC arcs.
What DC voltage ranges do your contactors support?

LETOP DC modular contactors support voltages from 12V to 1000V DC, with specialized high-voltage models available up to 1500V for utility-scale solar and energy storage applications.

Are your DC contactors suitable for solar power systems?

Yes, our DC contactors are specifically designed for photovoltaic applications with UV-resistant materials, wide temperature ranges, enhanced environmental protection, and compliance with solar industry standards.

Can your DC contactors handle battery system applications?
Absolutely. Our DC contactors are optimized for battery management systems with features including low coil power consumption, reliable switching under varying DC voltages, and enhanced safety for battery isolation applications.
What current ratings are available for DC applications?
LETOP offer DC modular contactors with current ratings from 16A to 100A, with specialized high-current models available for specific applications requiring higher switching capacity.
Do you provide contactors for electric vehicle charging applications?

Yes, we manufacture DC contactors specifically for EV charging infrastructure with automotive-grade reliability, enhanced arc suppression, and compliance with EV charging standards.

What coil voltages are available for DC control?

LETOP DC contactors support coil voltages including 12V, 24V, 48V, 110V, and 230V DC, with custom voltage options available for specialized applications.

How do you ensure safety in high-voltage DC applications?
Our high-voltage DC contactors incorporate enhanced insulation systems, extended contact gaps, reinforced arc chambers, and comprehensive testing to ensure safe operation at elevated DC voltages.
Can you customize DC contactors for specific applications?

Yes, we provide comprehensive customization including non-standard voltages, environmental protection upgrades, mechanical integration modifications, and application-specific optimizations.

What certifications do your DC contactors have?
