Drawout vertical construction with motorized racking mounting enhances safe maintenance and rapid breaker replacement in active panels. This design minimizes manual handling, reduces arc exposure, and speeds on/off operations during commissioning or service outages. In industrial switchgear, quick access translates to shorter downtime and improved availability. Four-pole configuration with a 4000 A continuous rating and 100 kA interrupting capacity provides robust fault protection for large motors and high-load feeders. The generous interrupt capacity helps coordinate protection with upstream devices and reduces nuisance trips, leading to lower maintenance costs and safer distribution. No trip unit is installed by default, offering a flexible platform ready for future protection upgrades and modular expansion as system needs evolve. Certification breadth—UL Listed, CE Marked, Lloyd's Register certified—ensures global acceptance and regulatory alignment, simplifying procurement and risk management in multinational projects. With its size and mounting compatibility, the Magnum unit fits standard drawout panels and retrofit scenarios, reducing installation time while ensuring reliable alignment and long-term performance. Overall, this breaker supports scalable protection strategies, improved coordination, and a clear path to compliant, efficient power distribution in harsh industrial environments.
