HEF213030 | Circuit Breaker | 30A | 1-Pole | 277V

HEF213030 is an industrial‑grade circuit breaker engineered for reliability in demanding environments. With a 30 ampere rating, a 1‑pole configuration, and a 277V operating capability, this unit is built to protect single‑phase circuits in commercial and industrial panels where precise specs matter.

• Current rating: 30A
• Pole configuration: 1‑Pole
• Voltage rating: 277V
• Reference part number: HEF213030 (ensures exact compatibility)

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, helping you avoid mismatches in panel design and protection requirements.

Designed for practical, real‑world use, this breaker is ideal for:

• Maintenance tasks where a direct replacement matches the existing 30A, 1‑pole, 277V configuration
• Retrofit projects that require updating older panels to current protection standards
• Replacement scenarios where uptime and reliable overcurrent protection are critical
• 277V single‑pole circuits common in lighting, control, and miscellaneous distribution apps

Why choose this specific part? The HEF213030 pairing delivers a precise fit for systems that demand exact amperage, single‑pole protection, and a 277V rating. By using the exact part number, you minimize compatibility risk and streamline procurement for service technicians and facilities managers alike. In practice, this means quicker swaps, consistent protection, and less downtime when servicing industrial electrical infrastructure.

Practical tips for installation and use:

• Cross‑check your panel model and the breaker’s part number (HEF213030) before replacing any unit.
• Power should be fully shut off and lockout/tagout procedures observed during replacement.
• Handle with care to avoid damage to terminals and the surrounding busbar connections.
• Store and transport breakers in a clean, dry environment to prevent corrosion or moisture exposure.
