HEG421020 | Circuit Breaker | 20A | 2-Pole | 480V

The HEG421020 Industrial Circuit Breaker delivers reliable protection for 480V systems in a compact 2-pole design. Built for maintenance, retrofit, and replacement projects, it ensures your electrical protection aligns with existing panels and wiring, minimizing downtime and compatibility risk.

Key specifications

• Amperage: 20A
• Poles: 2-Pole
• Voltage rating: 480V

Why choose HEG421020 for your project

When upgrading or replacing a circuit breaker in industrial equipment, matching the exact part number helps guarantee fit, trip characteristics, and electrical clearance. HEG421020 is the definitive reference for compatibility with systems designed for 480V and 2-pole protection. This specificity reduces the risk of mismatches that can cause nuisance trips or inadequate protection.

Ideal use cases

• Maintenance of 480V panels in manufacturing, processing lines, or industrial machinery where a 20A, 2-pole breaker is required.
• Retrofit projects where the existing panel demands a 2-pole breaker with a 480V rating and 20A trip capacity.
• Replacement scenarios where the original part number is HEG421020 to preserve electrical architecture.

Practical installation and compatibility tips

• Before ordering, confirm fit and ratings: the product notes emphasize verifying compatibility with your panel and the system voltage.
• Use the HEG421020 as the best reference part number to match against your equipment’s documentation and replacement history.
• Check that your panel supports 480V operation and a 2-pole configuration to ensure correct installation.
• Inspect mounting, terminal sizes, and trip curve compatibility with your panel lineup to avoid clearance or wiring issues.

Distinctive value for professionals

Rather than a generic substitute, this circuit breaker aligns with existing electrical architectures, helping technicians complete replacements with confidence, reduce downtime, and maintain consistent protection across your facility’s 480V network.
