Overview

The ABB THHQC2120 industrial circuit breaker (SKU: THHQC2120) from ABB - Electrification provides essential dual-function protection for commercial and industrial power distribution systems. This unit integrates a 1-pole Ground Fault Circuit Interrupter (GFCI) with a 2-pole 120/240V circuit breaker, both rated for 20 Amperes. The GFCI functionality is critical for preventing electrical shock hazards by detecting ground faults and quickly interrupting power. The 2-pole configuration is specifically designed for single-phase 120/240V circuits, commonly found in industrial and commercial settings. While the precise Ampere Interrupting Capacity (AIC) for the THHQC2120 is not explicitly stated in the provided catalog snippets, comparable ABB THHQB and THQC series breakers in the 20A range often feature a 22,000 AIC rating, indicating a substantial capability for safely interrupting fault currents. This breaker is an ideal choice for applications requiring both sensitive ground fault protection on a single circuit and standard 2-pole circuit interruption for a branch circuit. Engineered for reliability, the THHQC2120 ensures consistent performance and adherence to safety standards in demanding operational environments. Trust ABB's established expertise in electrical protection for your critical power infrastructure.
