NGB2B020B - 20 Amp Circuit Breaker

NGB2B020B - 20 Amp Circuit Breaker

If you're looking for an NGB2B020B circuit breaker, getting the details right matters. This Type NGB molded case circuit breaker is rated at 20 amps and has a 2-pole configuration for use in compatible panelboard applications. It has interrupting ratings of 25k AIC at 480VAC and 100k AIC at 240VAC, and it is also HACR rated. It measures 5.0 inches high, 2.0 inches wide, and 3.06 inches deep, and includes load-side terminals. The NGB2B020B is a good fit for maintenance and replacement work involving existing electrical equipment that calls for this particular NGB configuration. That's especially important with legacy systems, where amperage is only part of the picture—the breaker must also match the required pole count, mounting style, dimensions, voltage, and interrupting rating. Built to last and made for its intended application, the NGB2B020B gives electricians and maintenance teams a straightforward option when these specifications match the equipment already in place.

Key Features and Benefits

• 20-amp rating for circuits designed around this amperage.

Material Compliance and Certifications

• The NGB2B020B is HACR rated. No other material-compliance certifications were provided in the available specifications, so we won't assume certifications that aren't documented.
• For a replacement application, check the breaker markings and equipment requirements before installation. The part number, amperage, poles, voltage, interrupting rating, dimensions, mounting style, and terminal arrangement should all match the intended application.
  

Where It Works Best

• The NGB2B020B makes the most sense in compatible panelboards and legacy electrical systems that require a 20A, 2-pole Type NGB molded case breaker with these specific ratings and dimensions. It's particularly useful for maintenance and repair situations where the goal is to keep the existing equipment configuration intact.
• When matching a replacement breaker, don't stop at the 20A rating. Check the complete set of specifications. For the NGB2B020B, confirm the 2-pole configuration, Type NGB design, panelboard mounting, 25k AIC at 480VAC / 100k AIC at 240VAC ratings, physical dimensions, and load-side terminal configuration. A careful match helps ensure the breaker fits the equipment and intended application.
