HEG421030 | Circuit Breaker | 30A | 2-Pole | 480V

HEG421030 stands out as a robust industrial circuit breaker designed for demanding electrical environments. With a precise 30-amp rating across two poles and a 480V utility, it provides reliable protection for high-energy circuits while ensuring safe, simultaneous disconnection of both conductors when trips occur.

What this 2-Pole, 480V breaker delivers

• Consistent 30A protection for feeders and branch circuits, helping prevent overheating, insulation damage, and equipment wear.
• Two-pole design ensures both hot legs are disconnected together, improving safety for 480V systems and minimizing arc potential during a fault.
• High-voltage suitability tailored for industrial panels, machine controls, and other 480V applications where dependable protection is essential.
