Circuit breakers are safety devices that automatically switch off the circuit when an electrical fault trip is detected, protecting personnel and equipment from overloading. The 279-2-1-51F-9-9M-50-AH is a preset motor circuit protector designed to protect primary and motor circuits against possible short-circuiting, overloads, and ground faults.

This particular breaker is a two-step motor circuit protector that will protect the motor on two levels. The first level involves a thermal protector that will trip the breaker if the motor temperature exceeds 176 °F (80°C). The second level involves overload protection that will trip the breaker if the current draw exceeds the settings on the breaker.

The 279-2-1-51F-9-9M-50-AH is designed for two-speed motor applications, such as those found in rotary pumps, split-phase motors, and multi-speed fan motors. The device features a unique two-stage thermal element that allows the user to select the operating temperature of the device. This allows the user to increase the temperature setting to prevent short cycling during hotter months and decrease the temperature setting in cooler months.

In addition to the two-stage thermal element, the 279-2-1-51F-9-9M-50-AH also includes an overload element that can react quickly to detect any excessive current draw. If the current draw exceeds the set limits, the overload element will trip the breaker. The device also includes a test button that allows users to manually test the overloaded condition of the device.

The 279-2-1-51F-9-9M-50-AH can be used in multiple applications, ranging from simple two-speed motor applications to complex multi-speed motors. In addition, it is designed to provide reliable, fail-safe protection against any potential overloads and ground faults. Additionally, the device is designed to comply with UL, CSA, and RoHS standards.

The 279-2-1-51F-9-9M-50-AH is easy to install and includes a wrap-around mounting bracket that allows the breaker to be directly mounted to the panel. The device can also be directly mounted onto the motor. This makes it easier to access the breaker for testing or adjustment.

In conclusion, the 279-2-1-51F-9-9M-50-AH is a reliable, two-stage motor circuit protector designed to protect both primary and motor circuits against overloads, short-circuiting, and ground faults. It is designed to provide safe and reliable protection in multiple environments, such as two-speed motor applications, multi-speed fan motors, and rotary pumps. It is easy to install and is designed to meet UL, CSA, and RoHS standards. Overall, this circuit breaker is a great choice for any application that requires reliable and fail-safe protection.
