Circuit breaker accessory Rittal SV 9345.714 4-pole 500A bottom cable outlet

Rittal SV 9345.714 is a circuit breaker accessory designed as a 4-pole, 500 A adapter with a bottom cable outlet. Supplied as a single unit, the adapter provides a reliable connection interface for high-current circuit breaker installations and helps organise cable routing within control and distribution panels. The accessory is intended to integrate with compatible circuit breakers and mounting systems to ensure secure electrical contact and tidy conductor exit from the enclosure.

Advantages

The accessory offers a compact, purpose-built solution for routing high-current conductors through the bottom of the enclosure while maintaining firm mechanical and electrical connections. Its 4-pole configuration supports three-phase systems plus neutral and is rated for 500 A continuous current, reducing the need for custom terminal arrangements. The bottom cable outlet promotes neater cable management and easier panel assembly, minimizing strain on conductors and connection points.

Suitable for

• Three-phase distribution boards and control panels requiring a 4-pole, high-current adapter
• Installations where bottom cable exit is preferred for routing or space reasons
• Replacement or retrofit of existing circuit breaker connections in industrial switchgear
• Applications needing a single-unit solution for organised conductor termination at up to 500 A

When it may not be suitable

The adapter is not intended for use beyond its 500 A rating or in systems that require additional protective elements integrated into the accessory. It is not a substitute for a complete circuit breaker or for accessories that include built-in auxiliary contacts, mechanical interlocks, or monitoring modules.

Key specifications

• Poles: 4 (three phases + neutral)
• Rated current: 500 A
• Cable outlet orientation: bottom exit
• Supplied: single unit
• Application: connection interface for high-current circuit breaker installations in control and distribution panels

How to use

Install the adapter according to the panel and circuit breaker manufacturer instructions, ensuring power is isolated before beginning work. Position the accessory so the bottom cable outlet aligns with the intended conductor routing path. Secure mechanical fixation points and tighten electrical connections to the recommended torque values for the conductor material and cross-section. After installation, verify continuity and tightening, and perform insulation and functional tests as required by local electrical codes and safety standards.

What to consider before purchase

• Confirm compatibility with your circuit breaker model and the mounting system used in your enclosure
• Ensure conductor cross-sections and terminal types match the adapter's connection method and rated current
• Verify available space for bottom cable routing and clearance inside the panel
• Check applicable local standards and installation requirements for 500 A connections

Usage recommendations

Use appropriate conductor sizes and torque settings, maintain clearances for heat dissipation, and follow manufacturer and regulatory installation procedures. Periodic inspection and thermal scanning during commissioning can help ensure reliable operation at high currents.
