PGA36120U41A - 1200 Amp Circuit Breaker

PGA36120U41A - 1200 Amp Circuit Breaker

The Schneider Electric PGA36120U41A 1200 Amp Circuit Breaker is a high-performance molded-case breaker in the PowerPacT P-frame series, designed for industrial and commercial power distribution systems. Rated for 1200 A and built with a three-pole configuration, this breaker combines precise electronic trip control with excellent fault-clearing ability to protect your installations reliably. With the Micrologic 3.0A trip unit delivering Long-Time and Instantaneous (LI) protection modes, the PGA36120U41A ensures sensitive, accurate response to overloads and short circuits—giving you confidence your system is safeguarded without unnecessary nuisance trips. Its plug-in I-Line termination design, together with mechanical lugs on the load side, makes it easy to integrate into various panel and bus systems. Add to that its 18 kA interrupting rating at 600 V AC, and you get a breaker ready to handle harsh conditions in demanding environments.

Key Features and Benefits

• Micrologic 3.0A Trip Unit with LI Functions: Offers fine-tuned protection via Long-Time and Instantaneous modes, minimizing false trips while maintaining safety.
• High Fault-Current Clearing: Capable of interrupting 18 kA at 600 V AC (UL rating), ensuring it can handle high-stress fault conditions.
• I-Line Plug-In Mounting: Simplifies installation and replacement in existing panels while preserving standard footprint layouts.
• Interchangeable Trip Unit: The Micrologic unit can be swapped or upgraded in the field for flexibility in changing load conditions.
• Consistent Mounting Layout: Common mounting holes and handle-locations across the P series reduce design complexity and panel rework.
• Built for Harsh Environments: Constructed with durable materials to stand up to heavy industrial use with continuous performance.

Where It Works Best

• The PGA36120U41A shines in heavy-duty industrial and commercial electrical distribution settings. It’s ideal as a primary or feeder breaker in manufacturing plants, large commercial buildings, data centers, and critical facilities where reliability is non-negotiable. Use it in power distribution panels, switchgear, or infrastructure systems where fault currents can climb high and where you need exact trip coordination. Its plug-in I-Line style also makes it well-suited for retrofit applications or system upgrades where panel layouts are fixed.
