Eaton 3752A24G05 3752A 3-Pole 500 V Circuit Breaker Potential Transformer

Eaton 3752A24G05 is a rugged, three‑pole circuit breaker with a built‑in potential transformer, engineered for reliable protection and precise monitoring in high‑voltage electrical cabinets. With a 500 V rating and a substantial current handling capability, this model is purposefully designed for demanding industrial and commercial power systems where safety, accuracy, and minimal wiring clutter matter.

Why this model stands out

• Integrated potential transformer: The built‑in transformer support simplifies meter‑driven protection and monitoring workflows. It streamlines wiring, reduces the number of separate components, and supports accurate, real‑time data for protective relays and energy management systems.
• 3‑pole configuration for balanced protection: Three distinct conduction paths protect each phase, ensuring consistent overcurrent protection and coordinated trip behavior in 3‑phase power networks.
• High‑voltage readiness: With a 500 V rating, this breaker is suited for medium‑to‑high voltage distribution panels, switchgear, and industrial controls where robust fault interruption is critical.
• Trusted Eaton reliability: Built on Eaton’s legacy of durable protection devices, this part integrates into existing Eaton‑compatible lineups and control schemes with confidence.

Key features and practical benefits

• The combination of protection and metering capabilities in one device reduces wiring complexity and installation time for panel builders and maintenance teams.
• The potential transformer output provides reliable signals for metering, fault detection, and protective relays, helping you meet compliance and performance targets.
• A compact 3‑pole device consolidates protection across all three phases without needing separate transformers or auxiliaries for basic monitoring needs.
• Part number 3752A24G05 aligns with Eaton’s cataloging, making ordering, stocking, and cross‑referencing straightforward for facilities teams.
