SQUARE D HOM120DF Miniature Circuit Breaker, 20A, 1 Pole, 120VAC, 10KA, Plug In Mount

Square D HOM120DF circuit breaker is used in distribution panels, load centres and electrical panels to protect circuits and connected devices from potential hazards. This single-pole circuit breaker comes with plug mounting for efficient & straightforward installation and replacement within compatible electrical panels or load centres. This UL-listed dual-function circuit breaker offers comprehensive protection against overloads, short circuits, arc faults & ground faults. It features a clamp terminal accommodating two wires ranging from 14 to 8 AWG copper or aluminium. This circuit breaker has an operational ambient air temperature of 104 degrees F.

Working Mechanism:

• This breaker features an integrated arc fault circuit interrupter (AFCI), which identifies irregular circuit waveforms caused by arcing faults.
• If the AFCI component detects hazardous arcing patterns, it triggers a trip to disconnect the circuit and prevent potential fires.

Frequently Asked Questions:

Q. What is the difference between combination arc-fault and ground-fault circuit breaker?

A. A combination arc-fault circuit breaker detects both series and parallel arcing faults, helping prevent electrical fires caused by loose or damaged wiring, while a ground-fault circuit breaker detects imbalances in current flow between the hot and neutral conductors, providing protection against electrical shocks due to current leakage to ground.

Q. What is the acceptable wire range for the clamp terminal?

A. The clamp terminal can accomodate wire sizes ranging from 14 to 8 AWG of copper or aluminium.

Q. What is the short circuit current rating of this plug-in circuit breaker?

A. It has a short circuit current rating of 10kA.
