Mitsubishi Y-2005 Air Circuit Breaker For Low Voltage Power Distribution Systems

Meet the Mitsubishi Y-2005 Air Circuit Breaker, a heavy‑duty protection and switching solution engineered for reliable safeguarding of low‑voltage power distribution in industrial and commercial facilities. Built to endure demanding environments, this breaker delivers precise protection where it matters most.

Precision protection for your low‑voltage network

With the Mitsubishi Y-2005, you get an adjustable trip setting that lets you tailor protection to the exact needs of your system, enabling selective tripping and reducing unnecessary outages. Its high interruption capacity handles fault currents common in large facilities, supporting fast, safe interruption of faults while protecting upstream transformers and downstream equipment.

• Model/Part Number: Y-2005
• Breaker Type: Air Circuit Breaker
• Application: Low‑voltage power distribution systems
• Design: Heavy‑duty Mitsubishi construction
• Trip settings: Adjustable
• Interruption capacity: High
• Ideal for: Main incoming feeders, switchboards, and critical power distribution

Real-world use cases

• Switchboards serving data centers, manufacturing lines, or commercial campuses
• Main incoming feeders feeding large low‑voltage networks with demanding startup currents
• Critical loads where uptime is essential and protection coordination is key

Why this matters: adjustable trip settings enable coordination with other protective devices, minimizing outages to unaffected circuits during faults. The high interruption capacity ensures a clean interruption even in systems with elevated fault currents, protecting transformers, busbars, and downstream feeders. The robust, industrial‑grade construction reduces lifecycle maintenance and downtime due to component wear.

Who this is ideal for

• Facilities managers overseeing industrial plants, data centers, or commercial complexes
• Electrical engineers designing protective schemes for low‑voltage distribution
• Maintenance teams seeking a reliable, long‑lasting circuit breaker with adjustable protection

Compared to conventional low‑voltage breakers, the Y‑2005 emphasizes protection coordination and durability. Its Mitsubishi heritage means access to established service networks and proven performance in harsh environments, helping you reduce nuisance trips and extend asset life.

For facility upgrades or new installations, the Mitsubishi Y‑2005 Air Circuit Breaker combines trusted protection, configurable trip settings, and robust build to keep your power distribution safe and available when you need it most. Ensure proper matching with your switchgear and fault-current profile to optimize protection and reliability.
