170M6811D

The 170M6811D circuit breaker fuse module is a device manufactured and marketed by Eaton, one of the most prominent leaders in circuit breaker technology. The 170M6811D is designed to be used primarily in switchboards, but it can also be used in service entrance panels, and other similar electronic circuits. This module is equipped with a 71/2” wide, 17/8” high, 3-ace molded case, and is enclosed in a tough, solid dielectric material. It also has a break-resistant safety cover, providing extra protection against electrical shocks.

The 170M6811D can be used for medium-voltage residential applications, where higher ratings may be needed. Additionally, it is also used in commercial and industrial applications. This device is great for applications where circuit current or running amps might be an issue, since it has a 60A rating and a tripping point of 170A, which is highly useful in preventing the overload of circuits. The device is also equipped with thermal-magnetic trip mechanisms, which help to protect circuits and equipment from overcurrents. This tripping mechanism is divided into two major components: The short-circuit protection mechanism, which releases the circuit immediately when an overload occurs, and the time delay component, which delays the circuit breaker breaking until the fault current drops to a safe level.

The main components of the 170M6811D are the power busbar, the breaker, and the actuator. The power busbar supplies power to the device, and the breaker is responsible for allowing and preventing current from passing through the circuit. The actuator, which is integrated into the breaker, is what sets the number of amps passing through the circuit. In order for the breaker to work properly, it must be correctly sized and used only in accordance with the manufacturer’s instructions.

The working principle of the 170M6811D is relatively simple. When the power is supplied to the device, the breaker closes and allows current to flow through the circuit. When the applied current or running amps exceeds the rated level of the breaker, its internal components open the breaker, thus cutting off the power to the circuit. This way, the breach of the maximum current limit in the circuit is prevented and the circuit is safeguarded from overload or short circuit.

In summary, the 170M6811D is a highly reliable, medium-voltage circuit breaker that can be used in a variety of residential, commercial, and industrial applications. Its thermal-magnetic trip elements provide short-circuit protection and time delay tripping. This device is highly useful in ensuring that circuits remain within their rated current limits and that they are protected from excessive overloads or short circuits.
