Meet the HMA3400 Circuit Breaker — a rugged, industrial-grade protection device engineered for reliability in demanding power systems. With a 400A capacity and a 3-pole configuration for 600V services, this unit delivers precise, dependable fault protection where it matters most. Designed for maintenance, retrofit, and replacement projects, it ensures your protection specs stay exact and your downtime stays minimal.
Why this matters in real-world use — when your system runs on three-phase power, a matching 3-pole breaker guarantees synchronized disconnection across all lines, preventing unbalanced faults that can damage equipment. The HMA3400’s precise spec alignment minimizes compatibility guesswork during maintenance or retrofit, helping you protect motors, drives, and distribution panels without over- or under-protecting circuits.
Important compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, ensuring you choose the correct breaker for your panel, wiring, and protection requirements.
Practical tips for buyers: have your panel’s documentation on hand, verify the service voltage (600V), confirm the three-phase configuration, and double-check any panel-specific mounting or termination features listed by the original equipment manufacturer. If your goal is a straightforward, spec-aligned replacement or upgrade, the HMA3400 provides a clear, reliable path to maintaining safe, compliant industrial power distribution.
