The SQD circuit breaker comes in a compact 3/4 inch wide format for one-pole

circuit breakers, helping minimize panel space and footprint. The SQ-D

exclusive quick-open protection is standard on all 15 A and 20 A circuit

breakers-trip reaction within 1/60th of a second. No other circuit breaker

trips faster.

A comprehensive selection of 10kA rated circuit breakers is available including:

1) SQD one-pole standard circuit breakers (10 A to 70 A)

2) SQD two-pole standard circuit breakers (10 A to 200A)

3) SQD three-pole standard circuit breakers (10 A to 100 A)
