Wide fork busbar 3P 18mm 63A Schneider Electric R9XFH318

Schneider Electric wide fork busbar 3P 18mm 63A R9XFH318 is a three-pole insulated fork connector designed for electrical distribution and control panels. The component provides a secure mechanical and electrical connection between circuit breakers and busbar systems, with an 18 mm fork width and a 63 A rated current capacity. It is intended for installations where a compact, reliable connection is required within industrial and commercial electrical boards.

Advantages

The wide fork busbar offers a compact insulated design that simplifies mounting and reduces the risk of accidental contact. Its three-pole configuration enables simultaneous connection of all phases, saving assembly time and ensuring uniform current distribution. The 18 mm fork width provides a stable contact area for common circuit breakers and busbar profiles while the 63 A rating matches typical distribution circuit requirements.

Suitable for

• Electrical distribution panels in commercial buildings
• Industrial control cabinets and switchgear
• Connections to compatible miniature and molded-case circuit breakers
• Retrofit and new installations requiring compact insulated busbar connections

Key specifications

• Configuration: 3-pole (3P) insulated fork connector
• Fork width: 18 mm
• Rated current: 63 A
• Mounting: panel and busbar connection for circuit breaker interfaces
• Construction: insulated body with conductive fork terminals for secure contact

How to use

Install the wide fork busbar by positioning each fork over the corresponding circuit breaker terminal or busbar stud, ensuring correct phase alignment. Secure connections using the manufacturer-recommended fastening hardware and torque values for the receiving terminal. Verify that insulation clearances meet local electrical code requirements and that all terminals are tightened before energizing the circuit. Follow standard lock-out/tag-out and safety procedures during installation and maintenance.

Usage recommendations

Use the connector only with compatible circuit breakers and busbar profiles that accept an 18 mm fork width and a 63 A rated connection. Inspect terminals for signs of corrosion or damage before installation, and confirm torque settings according to the breaker or panel manufacturer to maintain reliable electrical contact.
