FB1020 - 20Amp Circuit Breaker

FB1020 - 20Amp Circuit Breaker

A tripped breaker isn't always the biggest problem. Finding a replacement that matches the existing equipment can take far longer than the repair itself. When you're servicing an electrical distribution system, using a breaker with the correct ratings and dimensions helps get the job finished without modifying the panel or replacing additional components.

The FB1020 is a 20 Amp, 1-pole molded case circuit breaker with a thermal-magnetic trip mechanism that responds to both overloads and short circuits. It features a non-interchangeable trip unit, is rated for operation in 40°C ambient conditions, and comes with load terminals already included.

Material Compliance and Certifications

Certification information was not provided in the available manufacturer specifications. Before replacing an existing breaker, confirm the amp rating, voltage rating, pole configuration, mounting arrangement, terminal configuration, and physical dimensions to ensure compatibility with the installed equipment.

Where It Works Best

The FB1020 is commonly used in compatible panelboards, switchboards, and electrical distribution equipment where a 20 Amp, single-pole thermal-magnetic circuit breaker is required. It's a practical replacement during routine maintenance, troubleshooting, or repairs in office buildings, schools, warehouses, manufacturing facilities, and other commercial or institutional properties.
