ED63B040 - 40Amp Circuit Breaker

ED63B040 - 40 Amp Circuit Breaker

The ED63B040 is a 40-amp, 3-pole circuit breaker from the Sentron series, built for use in commercial and industrial panelboards. It’s designed to handle standard protection duties—overloads and short circuits—without any unnecessary extras. If you’re working with a three-phase setup and need something that fits the ED6 frame, this is a straightforward match. This breaker uses a bolt-on connection, which helps keep it firmly in place once installed. That’s especially useful in panels where vibration or long-term reliability is a concern. It also comes with load-side terminals already included, so installation is a bit more convenient. The interrupting ratings are solid across multiple voltage levels, giving you confidence it can handle fault conditions when they happen. It’s also HACR rated, so it’s commonly used in HVAC-related systems, and it can be installed in reverse feed configurations if needed. Nothing complicated here—it’s a dependable breaker that fits, installs, and does its job.

Where It Works Best

• This model is typically used in commercial buildings, equipment panels, and HVAC systems where a 3-pole, 40-amp breaker is needed. You’ll see it in electrical rooms, control panels, and retrofit jobs where an ED6 frame breaker is already in place. It’s a practical choice when you just need something that fits right and works without issues.
