NA3P90 - 90Amp Circuit Breaker

NA3P90 - 90Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, getting the details right matters. The NA3P90 is a 3-pole, 90-amp thermal-magnetic circuit breaker made for compatible equipment that uses an NA-type Stab-On connection. It is rated 10 kAIC at 240VAC and measures 3.38 inches high, 3.0 inches wide, and 2.31 inches deep. These specifications give you several points to check against the breaker already in the equipment—not just the amperage. Check the part number, number of poles, voltage and interrupting ratings, connection style, and physical size before deciding whether it is the right fit. For compatible legacy electrical systems that call for this particular configuration, the NA3P90 provides the form and electrical characteristics needed for a like-for-like application. It's built to last when properly matched to the equipment, installed correctly, and used within its specified ratings.

Key Features and Benefits

• 90 amp, 3-pole configuration for equipment requiring these specific electrical characteristics.
• 10 kAIC at 240VAC provides a clear rating to compare with existing system requirements.

Where It Works Best

• The NA3P90 is best suited to compatible legacy electrical equipment that specifically requires an NA-type, 3-pole, 90A Stab-On thermal magnetic circuit breaker rated 10k AIC at 240VAC. It can be a useful match when maintaining an existing installation and preserving the equipment's required configuration.
  
• Don't determine compatibility by amperage alone. Check the part number, pole count, voltage, AIC rating, connection style, and dimensions against the existing equipment. A qualified electrical professional should confirm suitability before installation.
