HEG431020 | Circuit Breaker | 20A | 3-Pole | 480V

Meet HEG431020, an industrial circuit breaker built for reliability in demanding electrical environments. This 20A, 3-Pole unit is purpose-built for 480V systems, delivering balanced, three-phase protection that keeps equipment safe and downtime to a minimum.

Designed for maintenance, retrofit, and replacement projects where exact specs matter, HEG431020 pairs a clear part-number reference with robust electrical performance, so you can trust that you're choosing the right component the first time.

• Exact spec alignment: Amperage 20A, 3-Pole configuration, 480V rating—every specification matches typical industrial panel requirements.
• Three-phase protection: The 3-Pole design interrupts all live conductors in sync, reducing arc exposure and protecting motors, drives, and controls in your 3-phase system.
• Efficient maintenance and replacement: A straightforward drop-in replacement for compatible panels minimizes downtime during service events.
• Best reference for compatibility: The part number HEG431020 is the clearest confirmation of fit—verify this reference against your panel schedule before ordering.
• Versatile for retrofit projects: Ideal when upgrading legacy installations to a 480V three-phase distribution or replacing aging breakers with a unit that matches existing ratings.

Who benefits most: electrical technicians, facilities engineers, panel builders, and maintenance teams responsible for keeping industrial lines running smoothly. In practice, this breaker supports applications such as manufacturing lines, material handling, and process controls that rely on stable 480V three-phase power.

Practical tips for a smooth fit: check your panel's labeling for the exact 3-Pole, 480V specification; keep the HEG431020 on hand as a ready-to-install spare; and confirm the mounting arrangement and bus compatibility with your enclosure to avoid last-minute service delays.

Choose HEG431020 for confident, compatible protection that aligns with your 480V three-phase infrastructure. This isn't a generic substitute—it's the precise component designed to meet the exact needs of industrial power distribution.
