E2090 - 90Amp Circuit Breaker

E2090 - 90 Amp Circuit Breaker

The E2090 90 Amp 2-Pole Circuit Breaker is designed to provide dependable overcurrent protection for electrical distribution systems operating at 120/240VAC. Built with a thermal-magnetic trip mechanism, this breaker responds to both prolonged overload conditions and sudden short circuits, helping safeguard wiring, equipment, and connected loads. Its non-interchangeable trip unit ensures consistent protection calibrated specifically for the breaker’s rating, while the 40°C temperature rating supports reliable operation in common electrical panel environments. With a 10kA A.I.C. interrupting rating, the E2090 breaker is suited for applications requiring solid fault interruption capability in residential, commercial, and light industrial systems. The unit includes load terminals for secure installation, making it a practical replacement or upgrade for compatible panels using the E frame type.
