EHC3020 - 20Amp Circuit Breaker

EHC3020 - 20 Amp Circuit Breaker

When you’re maintaining or servicing an existing electrical system, the last thing you want is guesswork. The EHC3020 circuit breaker gives you a straightforward, compatible solution designed to match the specs your system already depends on. With a 3-pole configuration and 20-amp capacity, this breaker handles everyday load protection with consistency, helping safeguard equipment from overloads and short circuits without complicating your setup. Built on the EHC frame, this thermal-magnetic breaker uses a non-interchangeable trip unit, meaning its trip characteristics are fixed and reliable—exactly what’s needed when consistency matters in established systems. Rated for up to 480VAC and designed to operate in 40°C environments, it fits right into many commercial and industrial applications. Plus, with load terminals included, installation is more direct, saving time on the job. If you’re looking for a circuit breaker that aligns with your existing panel and does its job without unnecessary complexity, the EHC3020 is a practical, dependable choice built to last.
