1878785-2

1878785-2 application fields are wide-ranging, and can include the protection of motors, generators and against short circuits and overloads in the electrical industry, the protection of equipment with compatible voltage and capacity in general and the protection of low voltage consumers against overloads and short circuit damage. The 1878785-2 device is utilized to help in an emergency overload or short circuit condition by quickly isolating the power to allow for safe repair.

The 1878785-2 device is a type of manual-reset protective device or MRSD. This device is designed to disconnect the circuit when the power exceeds a predetermined level. When the pre-set power has been achieved, the device will trip and disconnect the circuit. The 1878785-2 has a built-in over-current protection feature to protect against over-current situations. It also has a reset switch located on the front panel which is used to reset the device if it trips.

The working principle of the device is relatively simple. It uses a thermal element that is heated by current passing through it. Once the set temperature is achieved, the 1878785-2 will trip and disconnect the circuit. The thermal element then cools down and the tripped 1878785-2 can be manually reset using the reset switch. Depending on the application, the device can be used for both AC and DC circuits.

The 1878785-2 is a versatile and reliable protective device that can be used in many industries. It is suitable for use with motors, generators and other electrical systems and is designed to offer maximum safety and protection. The device is easy to install and is also easy to reset when a tripped condition occurs. Additionally, it is relatively inexpensive compared to other protective devices and so is a cost effective choice.

In conclusion, the 1878785-2 is a manual-reset protective device that is designed to protect motors, generators and other electrical systems against short circuits and overloads. The device works by utilizing a thermal element that is heated by current passing through it, and once the pre-set temperature is achieved, the element will trip and disconnect the circuit. The 1878785-2 is an inexpensive and cost effective choice, and is an excellent choice for ensuring maximum safety and protection for electrical systems.
