How to choose
Start with the breaker series printed on the panel label, such as QO, QOB, or FA. Next, match the required 1-, 2-, or 3-pole configuration with the 100 amp rating. For heavy-duty applications, determine if the circuit requires a molded case switch or a motor circuit protector. Confirm your panel and breaker type are compatible before ordering.
