Why Choose the Rittal SV 9666.440 Air Circuit-Breaker Module?

The Rittal SV 9666.440 is an air circuit-breaker module for ISV distribution systems, designed to provide a structured mounting solution for circuit-breakers within low-voltage power distribution assemblies. As part of the Rittal SV / Ri4Power ISV system, this module enables panel builders to integrate compatible protective switching devices into a modular and professionally organised enclosure layout.

With a modular size of 2 WU (500 mm) × 2 U (300 mm), the SV 9666.440 provides additional installation width for larger circuit-breaker arrangements. Its modular construction supports efficient assembly, straightforward servicing and consistent positioning of switchgear within compatible Rittal ISV distribution systems.

The module incorporates a robust mounting arrangement and protective cover designed specifically for use within the ISV system. Its 500 × 300 mm format makes it suitable for industrial and commercial distribution applications where secure, accessible and organised installation of circuit-breaker equipment is required.

Key Advantages

  • Purpose-designed circuit-breaker module for Rittal ISV distribution systems.
  • Generous 2 WU (500 mm) mounting width for compatible circuit-breaker installations.
  • 2 U (300 mm) module height supports standardised ISV panel layouts.
  • Modular construction simplifies switchgear assembly and enclosure planning.
  • Provides organised and accessible positioning of protective switching equipment.
  • Suitable for professional industrial and commercial low-voltage distribution assemblies.

Key Features

  • Rittal SV / Ri4Power ISV circuit-breaker module.
  • Designed for installation of compatible circuit-breakers.
  • 2 WU (500 mm) width units.
  • 2 U (300 mm) height units.
  • Modular design for structured low-voltage distribution systems.
  • Protective cover for the installed switchgear area.
  • Designed for integration with compatible Rittal ISV components.
  • Supports orderly installation and servicing of circuit-breaker equipment.

Structured Circuit-Breaker Integration for Power Distribution

Circuit-breaker modules provide a dedicated mounting area for protective switching equipment within low-voltage distribution assemblies. A standardised modular layout helps panel builders position equipment consistently while maintaining suitable accessibility for installation, inspection, operation and maintenance.

The Rittal SV 9666.440 uses the modular ISV system dimensions to provide a 500 mm wide and 300 mm high installation area. This 2 WU × 2 U configuration makes the module particularly useful where a wider mounting space is required while retaining the structured layout of a Rittal ISV distribution assembly.

Typical Applications

  • Rittal Ri4Power ISV distribution systems.
  • Low-voltage electrical distribution assemblies.
  • Industrial switchgear installations.
  • Commercial building distribution panels.
  • Machine and production equipment power distribution.
  • Electrical control and protection systems.
