BB1075 is an integrated thermistor thermal overload relay from Allen-Bradley. It provides motor protection and can be used with a wide range of electronic motor starters.The primary purpose of the BB1075 is to prevent motor overloads by monitoring the motor's current draw and then tripping the motor circuit breaker if the current is excessive. The BB1075 also offers monitoring and protection for other motor and control components as well. It can be used to provide overload protection for a wide variety of AC and DC motor applications, including motor control centers, motor control centers with remote compartmentalized motor control, control panels, AC/DC circuits, and motor controllers. The BB1075 is also compatible with other Allen-Bradley motor control devices, such as the microLogix 1100, 1500, and 5000 Series PLCs.
