ER4-100N3PR is a type of disconnect switch components, which have a wide breadth of application, primarily used for switching electrical circuits. It is usually installed near the load end for both single phase and three phase circuits and at the service entrance. The disconnect switch can also be combined with electric meters, electric freeze protectors, manual motor starters, motor control centers, etc.

The disconnect switch consists of two parts, the circuit breaker and the enclosure. The circuit breaker houses the contacts, interrupter blades and arc chutes. The contacts are composed of moving parts and static parts and they can easily polarize – establish and retain the position of the external circuit. Interrupter blades are designed to interrupt the flow of current by creating an arc which is quenched by the arc chutes. The enclosure is the metal frame which houses the circuit breaker and provides a safe and secure environment for its components.

ER4-100N3PR is a type of 3 pole non-fusible disconnect switch components which has insulated poles and is designed for indoor use only. It has a voltage rating of 1000V and a current rating of 100A, along with a manual trip mechanism. It also has a non-interchangeable handle which can be locked in the open or closed position for safety. The disconnect switch components are UL listed and meets all the requirements of UL508, UL98, and the National Electrical Code.

The main purpose of this type of ER4-100N3PR disconnect switch is to provide a safe and reliable means of disconnecting power when performing maintenance or when servicing the equipment. This is done by simply turning the switch handle to its open position. The open position will disconnect the power from all the wires connected to the switch. It is also capable of switching currents up to 100A and can withstand up to 1000V of electricity due to its insulated poles.

The working principle behind ER4-100N3PR disconnect switch components is the same as with any other disconnect switch. When the handle of the switch is turned to the open position, the contacts of the switch just open up and disconnect the power lines from the switch. This happens very quickly and in accordance with the contacts which close the circuit when the handle is turned to the closed position. This is why it is important to note the current rating of the disconnect switch components before connecting to the power lines.

In conclusion, the ER4-100N3PR is a type of disconnect switch components which can be used for switching electrical circuits. It can be used for single phase and three phase circuits and can handle up to 100Amps of electricity and 1000V of voltage. It has an insulated case which allows for safety and reliability while the handle can be locked in the open or closed position for increased safety. Its working principle is simple; when the handle is turned to its open position, the contacts of the switch open and disconnect the power lines from the switch.
