EC2090 - 90Amp Circuit Breaker

EC2090 - 90Amp Circuit Breaker

When a circuit breaker needs replacement, finding the correct match matters. The EC2090 90 Amp 2-Pole Circuit Breaker is designed for use in compatible Type EC electrical systems, providing the form, fit, and function required to help keep existing equipment operating as intended. Whether you're performing routine maintenance, replacing a damaged breaker, or sourcing a component for an ongoing electrical project, matching the original specifications is essential for maintaining system integrity.

With a 90 Amp rating, 2-pole configuration, and 120/240VAC operating voltage, the EC2090 is commonly used in a variety of commercial, industrial, and institutional applications. Its thermal-magnetic trip mechanism combines overload protection and short-circuit protection into a single device, helping safeguard connected equipment and electrical circuits during abnormal operating conditions. The included non-interchangeable trip unit helps maintain the protection characteristics originally designed for the installation.
