Schneider Electric FGA34070 70A 3-Pole 480 V Circuit Breaker Potential Transformer

Overview

Meet the Schneider Electric FGA34070 — a rugged 70 A, 3-pole circuit breaker designed for 480 V systems, with an integrated potential transformer to deliver precise voltage sensing directly to protection relays and metering. This streamlined solution reduces external components and simplifies panel wiring, making it a practical choice for demanding industrial environments.

Key benefits

• Integrated potential transformer for immediate voltage sampling to protection relays and metering, eliminating the need for separate transformers and extra wiring.
• Three-pole protection ensures synchronized tripping across all phases, enhancing safety and system reliability in three-phase networks.
• 70 A current rating provides robust protection for moderate to high-load feeders without frequent nuisance trips.
• 480 V compatibility aligns with common industrial power distribution standards, making it suitable for data centers, manufacturing floors, and large facilities.
• Compact integration reduces panel footprint and simplifies installation, maintenance, and future upgrades.

Applications and use cases

Ideal for industrial power distribution where accurate voltage sensing and reliable overcurrent protection are essential. Use cases include:

• Switchgear and motor control centers in manufacturing plants with 480 V three-phase feeders.
• Control panels requiring metering input or relay protection without the clutter of separate PTs.
• Retrofits or new installations where minimizing wiring complexity and installation time is a priority.

Why this design matters

Traditional setups often rely on external potential transformers, which add wiring, calibration steps, and potential points of failure. The FGA34070’s integrated PT design provides:

• Cleaner panel layouts with fewer components.
• Faster commissioning through ready-to-use voltage sensing signals.
• Enhanced protection coordination thanks to consistent voltage sampling across the system.
