ND3800T35W - 800 Amp Circuit Breaker

ND3800T35W - 800 Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, the details matter. The ND3800T35W is an 800-amp, 3-pole N-Frame molded-case circuit breaker intended for compatible equipment that requires this specific Type ND configuration. It has a thermal-magnetic electronic design with a non-interchangeable trip unit and includes adjustable short-time pickup with an I²t short-delay ramp, plus ground-fault protection. Interrupting capacity is rated at 25 kA at 600 VAC, 50 kA at 480 VAC, and 65 kA at 240 VAC. The breaker is also HACR rated. Physically, it measures 16 inches high, 8.25 inches wide, and 5.5 inches deep, which is worth confirming along with the electrical ratings when matching it to existing equipment. One thing to keep in mind: the ND3800T35W catalog number does not include the rating plug or lug terminals. Check those items separately for the specific installation. For facilities maintaining older N-Frame equipment, this breaker provides the original-style form, fit, and functions needed for compatible systems. It's a straightforward, heavy-duty electrical component that's built to last when correctly applied and maintained.

Material Compliance and Certifications

• The ND3800T35W is HACR rated. No other material-compliance information or certification details were provided in the available specifications, so confirm additional certifications in applicable product documentation rather than assume them.
• That distinction is important for this Type of product page. Google's quality guidance places particular weight on factual accuracy and trustworthy information where incorrect technical information could affect safety.
  

Where It Works Best

• The ND3800T35W is a good fit for existing N-Frame electrical installations that require its specific physical and electrical configuration. Typical applications include maintenance and replacement work in compatible commercial and industrial electrical distribution equipment.
• This is really about matching the breaker to the system. Check the 800A rating, three poles, Type ND/N-Frame configuration, A.I.C. ratings, dimensions, trip functions, and required accessories against the equipment being serviced. Since the rating plug and lug terminals aren't included in the catalog number, verify those components separately.
