E42B080 - 80Amp Circuit Breaker

E42B080 - 80 Amp Circuit Breaker

The E42B080 molded case circuit breaker is designed for dependable overcurrent protection in electrical distribution systems that require an 80-amp, 2-pole breaker within an E42 frame. Built for consistent operation in commercial and industrial panelboards, this bolt-on circuit breaker installs securely and includes load-side terminals for straightforward conductor connections. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, the E42B080 helps safeguard circuits and connected equipment from overloads and short circuits. Rated for 40°C environments and HACR applications, this breaker is commonly used in HVAC-related systems and other equipment where reliable circuit protection is required. Its form and fit make it suitable for maintaining or servicing compatible legacy electrical systems while meeting the electrical ratings required for safe operation. Products in this category are built to last and intended for long-term service in demanding electrical installations.
