Reduce costs by fitting more circuits into smaller panels. This 15/20 Amp 2 pole 120/240V quad circuit breaker takes up less space (1/2" per pole) allowing for reduction in the size of the current panel or expansion of panel capacity for applications requiring more circuits. Using quad tandems is ideal for remodel, multi-family and light commercial construction. It has a 10,000 Amperes Interrupting Rating (AIR) and measures 3" x 3" x 2".
