NEB2B070B - 70 Amp Circuit Breaker

NEB2B070B - 70 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the details have to line up. The NEB2B070B is a 70-amp, 2-pole molded-case circuit breaker with a Type NEB configuration and panelboard mounting. It measures 5.5 inches high, 2 inches wide, and 3 inches deep, giving you the basic dimensions needed to compare it with the breaker already in your equipment. Electrically, the NEB2B070B has an A.I.C. rating of 35kA at 480VAC and 85kA at 240VAC. It's also HACR-rated at 40.25°C and includes load-side terminals. This breaker makes sense for maintenance and replacement work on compatible legacy electrical systems where the original form, fit, and ratings must be maintained. It's built to last and, more importantly, built for a specific job, so checking the part number, ratings, mounting style, and dimensions against your existing equipment is always a smart first step.

Key Features and Benefits

• 70-amp rating for applications that require a 70A breaker.
• 2-pole design for compatible two-pole electrical circuits.
• Type NEB molded case construction for use with equipment designed around this breaker configuration.
• 35kA @ 480VAC and 85kA @ 240VAC A.I.C. ratings provide clear specifications for matching the breaker to the application.
• Panelboard-mount configuration for compatible panelboard installations.
• HACR rated for applications where this designation is required.
• Includes load-side terminals, matching the specified NEB2B070B configuration.
• Compact 5.5 x 2.0 x 3.0-inch size makes it easier to compare physical dimensions when identifying a replacement.
• Well-suited to legacy equipment maintenance and replacement where maintaining the required form, fit, and function is important.

Material Compliance and Certifications

• The NEB2B070B is HACR rated. This designation may matter when matching a breaker to compatible heating, air-conditioning, or refrigeration equipment that specifies an HACR-rated circuit breaker.
• No other material compliance or certification details were supplied for this breaker. For that reason, confirm additional certifications or designations in the applicable equipment documentation rather than assume them.
• As with any replacement circuit breaker, check the complete specification before installation. The part number, amperage, number of poles, voltage, A.I.C. rating, physical size, mounting method, and terminal configuration all matter when determining compatibility.

Where It Works Best

• The NEB2B070B is intended for compatible panelboards and electrical distribution equipment that require a 70 amp, 2-pole Type NEB molded case circuit breaker. It's especially relevant when you're maintaining an older electrical system and need a replacement that matches the required configuration without changing the installation design.
• If you already have an NEB2B070B in the equipment, start by comparing the existing breaker's specifications with those listed here. If you're cross-referencing another breaker, don't rely on the 70 amp rating alone. Also check the pole configuration, A.I.C. ratings, dimensions, panelboard mounting arrangement, and terminals.
• For legacy electrical equipment, a close match matters. Confirm compatibility with the panelboard or equipment requirements before installation, and have the breaker installed in accordance with applicable electrical codes and qualified electrical practices.
