Eaton E110MR11B is a 1-pole, 10A type E Magnetic circuit breaker. It is a molded-case circuit breaker, designed for residential and commercial use in circuit protection applications. The E110MR11B features a common trip design, which trips the entire circuit when an overload occurs, providing increased protection for your electrical circuit. The E110MR11B has an adjustable, reversible, thermal-magnetic trip element which protects against both overload and short circuits. It also has a manual test switch, so you can easily check the status of your circuit. The E110MR11B has a thermal-magnetic trip curve, meaning that it has a faster trip response time in the event of an overload.
