Switch-disconnector adapter Rittal SV 9342.610, 3-pole CB device adapter for 250 A, bottom cable outlet

Rittal SV 9342.610 is a 3-pole switch-disconnector / circuit-breaker adapter designed for 250 A applications with a bottom cable outlet. It functions as a mounting and connection accessory to integrate switch-disconnector or circuit-breaker devices into electrical enclosures, enabling secure electrical connection and guided conductor routing. Built for use in control cabinets and distribution panels, the adapter simplifies installation and supports reliable operation of protection and switching equipment.

Advantages

The adapter provides a compact and standardized mounting interface for 3-pole CB devices rated for 250 A, ensuring consistent alignment and mechanical support within enclosures. Its bottom cable outlet facilitates tidy conductor routing and easier access for incoming or outgoing cables. The design reduces installation time by providing a ready-made connection and mounting solution that is compatible with typical switch-disconnector assemblies used in industrial and commercial panels.

Suitable for

• Mounting 3-pole switch-disconnectors or circuit-breakers up to 250 A in control cabinets
• Panel and distribution board installations requiring bottom cable outlet routing
• Industrial and commercial electrical installations where standardized adapter mounting is preferred
• Retrofit or replacement tasks where a reliable mechanical and electrical interface is required

When it may not be suitable

This adapter is intended specifically for 3-pole CB devices rated up to 250 A and for installations that accept a bottom cable outlet. It is not suitable for devices with different pole counts, higher current ratings, or enclosures that require top or side cable entries. Also, where a custom busbar or non-standard mounting is used, this standard adapter may not provide the required interface.

Key specifications

• Poles: 3-pole configuration suitable for three-phase connections
• Rated current compatibility: for devices up to 250 A
• Cable exit: bottom cable outlet for guided conductor routing
• Application: mounting and connection accessory for switch-disconnectors/circuit-breakers in enclosures
• Mechanical function: provides standardized mounting and secure electrical connection

How to use

Install the adapter into the enclosure at the intended mounting position, aligning it with the enclosure cut-out and fastening points. Fit the compatible 3-pole switch-disconnector or circuit-breaker onto the adapter according to the manufacturer's mounting instructions so that the device is mechanically secured and electrical terminals align with the bottom cable outlet. Route incoming and outgoing conductors through the bottom outlet, make the required electrical connections and tighten terminations to the torque values specified by the circuit-breaker manufacturer. Verify correct mechanical fastening and perform electrical tests before energizing the circuit.

What to consider before purchase

• Confirm compatibility with the specific switch-disconnector or circuit-breaker model and its mounting dimensions
• Ensure the enclosure layout permits a bottom cable outlet and sufficient cable bending space
• Verify that the adapter supports the required current rating (up to 250 A) and pole configuration
• Check that terminations and connection clearances meet applicable electrical standards and local regulations

Usage recommendations

Follow the circuit-breaker manufacturer's installation and torque specifications, use appropriate cable lugs and ferrules for conductor terminations, and ensure proper strain relief and segregation of power and control wiring when routing through the bottom outlet.
