EC2040 - 40Amp Circuit Breaker

EC2040 - 40Amp Circuit Breaker

When keeping an existing electrical system operating as intended, using the correct replacement circuit breaker matters. The EC2040 is a 40 Amp, 2-pole thermal-magnetic circuit breaker designed for use in compatible Type EC electrical distribution equipment, helping maintain the original protection requirements of your system without changing its design or configuration.

Built for 120/240VAC applications, the EC2040 is commonly used on branch circuits where both poles must operate together. In many commercial, industrial, and facility maintenance environments, matching the original breaker specifications is essential to preserving system integrity and ensuring equipment continues to operate as designed. Whether you're replacing a failed breaker during routine maintenance or servicing an existing installation, this breaker provides the form, fit, and function expected of a compatible Type EC replacement.

With a 10kA interrupting capacity, the EC2040 is intended for properly matched electrical systems requiring a 40 Amp, 2-pole circuit breaker. Built to last, it remains a practical solution for commercial and industrial facilities that depend on compatible EC-series equipment and need a replacement breaker that maintains original equipment specifications.
