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.
