ER4-100N3PB Disconnect Switch Components Application Field and Working Principle A disconnect switch is an assembly of components that enables the isolation of electrical equipment from the power supply when maintenance is required or operations are complete. One such disconnect switch is the ER4-100N3PB disconnect switch from Eaton Electronics Inc. This section will provide an introduction to this switch and its application field as well as its working principle.The ER4-100N3PB disconnect switch is designed to provide a convenient way to turn off electrical equipment when required. It is a single-pole, three-phase switch with a voltage rating of 480 volts and a current rating of 100 amperes. The device also incldues a main contactor rated for 600 volts and 100 amperes, an auxiliary contact (normally open) rated at 300 volts, and a terminal block for wire termination. Additionally, the device is certified both UL and CSA, meaning that it has been rigorously tested to meet safety standards and can be used in both commercial and residential applications.The ER4-100N3PB is most commonly used in applications involving difficult access locations. It comes with an adjustable handle which can be locked into any position up to 180°, ensuring that it can be used in the most compact and difficult to access locations. Additionally, the switch is designed to be easily installed in tight spaces, requiring only four inches of top clearance and five inches of side clearance. In terms of its working principle, the ER4-100N3PB is an interruption device designed to provide over-current protection. When the switch is open, the power is cut off and the current is prevented from flowing. When closed, the power is restored, allowing current to flow. The device also includes safety features, such as an auxiliary contact which can be used to activate other safety measures, for example, the locking of the handle to prevent accidental changes in the position of the switch.In conclusion, the ER4-100N3PB is a versatile and reliable disconnect switch suitable for difficult access locations. It is UL and CSA certified, easy to install, and features overcurrent protection and other safety measures. Whether in a commercial or residential setting, the ER4-100N3PB is a great choice for protecting electrical equipment.
