Product Description
The EATON sqd-qo250 is a 2-pole miniature circuit breaker (MCB) rated for 50 amps at 120/240 volts with a 10 kA interrupting capacity. It provides overcurrent and short-circuit protection for branch circuits in residential and light commercial electrical panels. Licensed electricians install this breaker as a direct panel-mount component, and its compact form factor suits standard load center applications. The 10 kA interrupt rating makes it suitable for installations where fault current levels demand reliable protection.
This circuit breaker is used in residential and light commercial branch circuit applications where 2-pole, 50-amp protection is required. Typical installations include circuits serving electric ranges, HVAC equipment, water heaters, and sub-panels. It is designed for use in compatible load centers and panel boards that accept QO-style miniature circuit breakers.
