Materials and Construction

XENHO Residential Miniature Circuit Breaker is built with high-performance materials to ensure long-term reliability and safety.

1. Flame-Retardant Housing

The Residential Miniature Circuit Breaker features a UL94 V-0 flame-retardant engineering plastic housing, offering good heat resistance, insulation, and impact strength. It resists aging and deformation, ensuring long-term structural stability. All plastic components are halogen-free and RoHS-compliant, preventing toxic gas emission in case of fire.

2. High-Purity Copper Conductors

Internal conductors use high-purity electrolytic copper for superior conductivity and corrosion resistance, ensuring low contact resistance and minimal temperature rise. Tin-plated surface treatment enhances oxidation and moisture resistance for stable connections in humid environments. Conductor design complies with IEC 60947 standards, ensuring secure crimping and preventing loosening or overheating.

FAQ

Q1: What is the difference between 4.5kA and 10kA RMCB?

A: 10kA RMCB can handle higher short-circuit current, suitable for more demanding electrical systems.

Q2: Can this RMCB be used for DC applications?

A: Yes, we provide both AC and DC versions depending on project requirements.

Q3: Is it waterproof?

A: The breaker itself is IP20. For waterproof needs, it should be used with an enclosure.
