FC34020 - 20 Amp Circuit Breaker

FC34020 - 20 Amp Circuit Breaker

Even if two circuit breakers look nearly identical, they aren't always interchangeable. Before replacing your existing breaker, it's a good idea to compare the part number, breaker type, frame, amperage, pole count, voltage rating, interrupt rating (A.I.C.), dimensions, and terminal configuration with the original unit.

The FC34020 is a 20 Amp, 3-pole Type FC thermal-magnetic molded case circuit breaker made for use in compatible I-Line panelboards. Its thermal-magnetic trip mechanism provides two levels of protection.

Material Compliance and Certifications

• Before replacing an existing breaker, verify that the part number, breaker type, frame, amperage, pole count, voltage rating, interrupt rating (A.I.C.), dimensions, and terminal configuration all match the original equipment. Taking the time to compare these details helps ensure compatibility and allows the replacement breaker to provide the intended form, fit, and function.
• The HACR Type classification makes this breaker suitable for applications where that designation is specified. Installation should always follow the National Electrical Code (NEC), applicable local electrical codes, and the equipment manufacturer's installation requirements.
• No additional certifications beyond the provided product specifications are stated.
  

Where It Works Best

The FC34020 is commonly installed in I-Line panelboards serving commercial buildings, manufacturing facilities, schools, healthcare facilities, industrial plants, and other three-phase electrical distribution systems. It works well for maintenance and repair projects where maintaining the original breaker's ratings and physical dimensions is important. When the existing specifications match, the FC34020 delivers the form, fit, and function needed to keep compatible electrical equipment operating as intended.
