Square D HOMT1515225 Homeline Quad‑Tandem Miniature Circuit Breaker

Overview

The HOMT1515225 is a compact, quad-tandem miniature circuit breaker from Square D’s Homeline series. Designed to maximize space within a load center, this breaker combines two single-pole 15-amp breakers and one two-pole 25-amp breaker (common trip) into a single unit that fits in just two panel spaces. It’s ideal for residential or light commercial applications requiring multiple circuits in limited space.
