FD1020 - 20Amp Circuit Breaker

FD1020 - 20Amp Circuit Breaker

A failed breaker can bring an entire panel—or an important piece of equipment—to a standstill. When you're replacing an existing unit, getting the right frame, ratings, and trip characteristics matters far more than making changes to the system. The FD1020 is a 20 Amp, single-pole Eaton Series C molded case circuit breaker that's commonly used as a direct replacement in compatible electrical distribution equipment. Its F-frame construction, T186 thermal magnetic trip unit, and load-side terminals match the published configuration for applications requiring this specific breaker.

Material Compliance and Certifications

The FD1020 is UL Listed and manufactured to the published electrical ratings and configuration for this model. It is intended to respond to overload and short-circuit conditions within its specified ratings. Before installation, verify compatibility with the existing electrical system, including frame size, amperage, voltage, interrupting capacity, pole configuration, and terminal arrangement. Installation should always follow applicable electrical codes and manufacturer recommendations.

Where It Works Best

The FD1020 is frequently found in commercial buildings, manufacturing facilities, schools, healthcare facilities, and other properties that rely on Series C F-frame distribution equipment. It's a practical replacement when an existing breaker has failed or when keeping spare breakers on hand is part of a preventative maintenance program.
