MCB Box YCX8-BFS

The YCX8-BFS is a high-grade, integrated protection enclosure designed to house and organize critical electrical components like Miniature Circuit Breakers (MCBs), fuses, and surge protectors. Far more than a standard electrical MCB box, this robust unit provides a centralized, protected hub for managing circuit distribution and safety. Whether you're consolidating PV strings in a solar array or organizing circuits in a demanding outdoor setting, this waterproof MCB box offers reliability and safety in one compact solution. Its IP65-rated enclosure ensures total protection against dust and water jets, making it an ideal outdoor electrical enclosure for residential, commercial, and industrial applications.

Key Features & Technical Highlights

• Integrated All-in-One Protection: This is not just an MCB box for home or a simple enclosure. It comes pre-configured as a complete PV combiner box with integrated DC-rated MCBs (YCB8 series), fuses (YCF8 series), and a Type II Surge Protection Device (SPD), offering comprehensive overcurrent, short-circuit, and surge protection for your system.
• Superior Environmental Protection: With a degree of protection rated at IP65 and impact resistance of IK10, this weatherproof electrical box is built to withstand harsh outdoor conditions, from driving rain to physical knocks.
• Flexible & Scalable Configuration: Available in multiple models (e.g., YCX8-BFS 2/1, 4/2, 6/1) to support various input/output string configurations, from consolidating 2 strings into 1, up to 6 strings into 2. This makes it a versatile distribution board for different project scales.
• High Electrical Ratings: Engineered for demanding applications, it supports a maximum voltage of 1000VDC and continuous currents up to 63A or 125A, ensuring compatibility with modern high-power solar panels and electrical circuits.
• Safe & Compliant: All internal components, including the DC circuit breaker and fuse holder, are designed and tested to meet rigorous international safety standards, including IEC 60947-2, guaranteeing safe operation.

Frequently Asked Questions (FAQ)

What is an MCB box?

An MCB box, or Miniature Circuit Breaker box, is a protective enclosure that houses one or more MCBs—safety devices that automatically switch off an electrical circuit during abnormal conditions like overload or short circuit. Our YCX8-BFS model is an advanced electrical enclosure that integrates these breakers with other protective components for enhanced system safety.

What is the price of an MCB box?

The price of an MCB box varies significantly based on its size, material, protection rating (like IP65), and included components (e.g., with or without breakers, SPDs). Our YCX8-BFS series offers value by including multiple protection devices in one weatherproof enclosure. Please contact us for a detailed quote based on your specific model and configuration requirements.

What is the price for a 12-way MCB box?

We specialize in configurable enclosures for specific applications like solar. While we offer models with multiple input ways (like 4-in or 6-in), for a standard 12-way AC distribution board, we recommend checking our other product lines. Contact our sales team with your exact specifications for the most accurate MCB box 12 way price.

Is the MCB box waterproof?

Yes, absolutely. The YCX8-BFS is rated IP65 waterproof, meaning it is completely dust-tight and protected against low-pressure water jets from any direction. This makes it a perfect outdoor waterproof electrical box for solar installations or any external electrical setup.

Can this box be used for home solar systems?

Yes, it is an excellent choice for home solar panel systems. Its integrated protection safeguards your investment from electrical faults, and its IP65 rating ensures long-term reliability on your rooftop. It simplifies wiring by combining multiple PV strings safely into one waterproof enclosure.
