Frequently Asked Questions

Get answers to common queries about our products and services.

What is the difference between RCCB and RCBO?

An RCCB (Residual Current Circuit Breaker) protects against earth leakage currents only. An RCBO (Residual Current Breaker with Overcurrent protection) combines both earth leakage protection and overcurrent protection (overload and short-circuit) in a single device.

Are Dada circuit breakers compliant with international standards?

Yes, all Dada circuit breakers are designed and tested in accordance with IEC 60898 (for MCBs), IEC 60947-2 (for MCCBs and ACBs), and other relevant international standards.

Can I use DC MCBs for solar power systems?

Absolutely. Dada offers DC miniature circuit breakers like the DAB7-63 series specifically designed for photovoltaic (PV) systems, providing reliable protection in solar installations.

Do you offer OEM/ODM services?

Yes, SHANGHAI DADA ELECTRIC supports OEM and ODM partnerships. We can customize branding, packaging, and technical specifications based on client requirements.
