NEB3B070B - 70Amp Circuit Breaker

NEB3B070B - 70Amp Circuit Breaker

When you replace a circuit breaker in an existing panelboard, the specifications have to match. The NEB3B070B is a 70-amp, 3-pole molded case circuit breaker with a Type NEB configuration and panelboard mounting. It is rated 35k AIC at 480VAC and 85k AIC at 240VAC, giving you two key ratings to check against your equipment requirements. This breaker is also HACR-rated and carries a 40°C rating. At about 5.5 inches high, 3 inches wide, and 3 inches deep, it has a compact footprint that matches the breaker it replaces. Load-side terminals are included. For electricians, maintenance departments, and facilities working with existing electrical equipment, this is the kind of breaker where the details matter most: 70 amps, three poles, the correct interrupting rating, Type NEB construction, and the right mounting arrangement. Its molded-case construction is built to last and designed for its intended electrical application.

Key Features and Benefits

• 70-amp rating for compatible circuits requiring a 70A breaker.
• Three-pole design for applications requiring 3-pole circuit protection.
• Type NEB configuration for compatible electrical equipment.
• Panelboard mount for the intended panelboard installation.
• Rated 35 kA at 480VAC and 85 kA at 240VAC.
• HACR rated for compatible heating, air-conditioning, and refrigeration applications where required.
• 40°C rating as specified for this breaker.
• Includes load-side terminals for the applicable connection arrangement.
• Molded case construction provides a durable enclosure that's built to last in its intended use.
• Compact 5.5" x 3" x 3" dimensions make it easier to compare the physical size with an existing breaker before installation.

Material Compliance and Certifications

• The NEB3B070B is HACR rated and has a specified 40°C rating. The available specifications provide no other material compliance or certification information, so do not assume additional certifications.
• As with any replacement circuit breaker, don't rely on amperage alone when checking compatibility. The breaker type, number of poles, voltage, interrupting rating, mounting configuration, dimensions, and requirements must match the intended application. Follow applicable electrical codes and equipment requirements during installation.
  

Where It Works Best

• The NEB3B070B is intended for compatible panelboard applications, particularly where an existing electrical system calls for a Type NEB, 70 amp, 3-pole molded case circuit breaker.
• It's a practical choice for maintenance and replacement work where maintaining the correct form, fit, and electrical characteristics matters. The combination of a three-pole configuration, panelboard mounting, HACR rating, 40°C rating, and specified AIC ratings gives technicians the information they need to determine whether it matches the existing application.
• Before installation, compare the part number, amperage, poles, AIC and voltage ratings, physical dimensions, and mounting arrangement with the breaker and equipment specifications already in place. With electrical replacement components, getting those details right matters most.
