PDG21G0040TFFJ - 40 Amp Circuit Breaker

PDG21G0040TFFJ - 40 Amp Circuit Breaker

The Eaton PDG21G0040TFFJ is a 40-amp, 1-pole molded case circuit breaker in the Global Rated Power Defense line. It uses a Frame 2 design and is rated 35 kA at 277 VAC. This model has a fixed trip and comes with line and load lugs. If you're trying to match an existing breaker, those details are worth checking closely. The PDG21G0040TFFJ measures 1.38 inches high, 6 inches wide, and 3.5 inches deep, so you can compare its dimensions along with the electrical ratings before deciding whether it's right for the equipment you're working on. It's a straightforward option for commercial or industrial applications that specifically call for a 40A, single-pole breaker with these ratings.

Material Compliance and Certifications

• Certification and material-compliance requirements aren't the same for every job. Before installing the PDG21G0040TFFJ, check the manufacturer's documentation and the breaker's markings to confirm any required listings, certifications, or compliance information for your application. This is particularly important when a project has specific code or equipment requirements.

Where It Works Best

• This breaker makes the most sense for compatible commercial and industrial electrical distribution equipment that calls for a 40A, 1-pole molded-case circuit breaker rated at 35kA at 277 VAC. It can also be useful when you're replacing an existing breaker and need to match the original unit as closely as possible.
• And here's something worth remembering when you're comparing breakers: 40 amps isn't the whole story. Check the complete part number, number of poles, voltage, interrupting rating, frame, trip type, lug configuration, and physical size. Two breakers can look similar at first glance and still have important differences.
• For safety and proper operation, breaker compatibility should be verified before installation, and electrical work should be performed by qualified personnel in accordance with the equipment manufacturer's requirements and applicable electrical codes.
