RCCB FAQ

Which company’s RCCB is best?

The best RCCB comes from manufacturers that control the entire production process. HUYU, as an Eaton joint‑venture partner, delivers IEC‑certified residual current circuit breakers with consistent quality and competitive factory pricing.

Are any circuit breakers made in the USA?

Yes, several brands manufacture in the USA. However, many global companies source RCCBs from specialized manufacturers like HUYU, which offers factory‑direct OEM solutions with the same IEC, UL, and KEMA certifications.

Who are the top 10 circuit breaker manufacturers?

Top lists often include global names, but HUYU stands out as a specialized OEM behind many of them. With our Eaton joint venture, we produce RCCBs that match the quality of the biggest brands at competitive factory pricing.

Is Square D owned by Schneider?

Yes, Square D is a brand of Schneider Electric. As an independent manufacturer, HUYU provides compatible OEM RCCB solutions that meet or exceed the performance of major brands, with full customization available.

What is a residual current circuit breaker?

A residual current circuit breaker (RCCB), also known as an RCD, detects earth leakage currents and disconnects the circuit to prevent electric shock and fire hazards. Unlike an RCBO, it does not include overcurrent protection. HUYU manufactures a full range of RCCBs for global markets.

Is an RCD the same as a GFCI?

They serve similar purposes but differ in standards and terminology. RCD (Residual Current Device) is the term used in IEC standards, while GFCI (Ground Fault Circuit Interrupter) is used in North American UL standards. HUYU RCCBs are designed to meet IEC requirements and can be customized for various markets.
