MGA36700 - 700 Amp Circuit Breaker

MGA36700 - 700 Amp Circuit Breaker

The MGA36700 700 Amp Circuit Breaker from Schneider Electric is a high-performance molded-case protection device designed to guard your electrical installations against overloads, short circuits, and fault conditions. Built on the PowerPact M frame, this 3-pole breaker is rated for 600 VAC and features an 18 kA interrupting capacity under UL 489 standards. Thanks to its ET 1.0 electronic trip unit, you get flexible protection settings and real-time communication potential, making it well suited for modern industrial control systems and demanding power distribution environments.

Key Features and Benefits

• Precision Protection: The ET 1.0 electronic trip unit delivers smarter, adjustable protection compared to fixed thermal-magnetic styles — so your system is safeguarded without undue nuisance tripping.
• High Fault Tolerance: With an interrupting rating of 18 kA at 600 VAC, plus higher ratings at lower voltages (35 kA at 480 VAC, 65 kA at 240 VAC) under UL 489, this breaker can handle high fault currents.
• Consistent Performance Footprint: It utilizes the I-Line bracket system for simple plug-in mounting, making installation or replacement in existing switchgear straightforward.
• Built for Expansion: The breaker supports modular add-ons (such as auxiliary switches or shunt trips), giving you more control options as system needs evolve.
• Environmental Conscience: As a Green Premium product, it's RoHS and REACh compliant, mercury-free, and PVC-free, minimizing ecological impact while maintaining reliability.
