ER3R-100J3PB

Disconnect Switch Components are an integral part of a wide array of industry applications. With an ever-increasing need for more reliable power for operations, it is more important than ever that these components are installed properly and tested for safety and longevity. One such component is the ER3R-100J3PB, manufactured by Rockwell Automation. This device is a robust, medium-voltage disconnect switch that provides an essential disconnecting and grounding function in a variety of applications.

The ER3R-100J3PB is an integral part of a wide range of power and process automation solutions. It is especially well suited for medium-voltage installations which require reliable load isolation and the safe, efficient transfer of power. The ER3R-100J3PB is rated from 307-600 Volts AC, 50/60 Hz, and is designed to provide a safe, reliable disconnection solution in harsh or hazardous environments, where the elements can cause damage to other equipment. The device is also UL/CSA/IEC rated, ensuring that it meets the highest standards of quality and safety in its field.

The ER3R-100J3PB is a robust and durable disconnect switch. It has a hermetically sealed stainless steel enclosure that ensures the highest degree of protection against the elements. It also features an external bolt-on contact arrangement, providing maximum protection against arcing, and with an adjustable limit switch to ensure accurate trip settings, this allows for easy testing of the system prior to installation.

The ER3R-100J3PB also features a modular design, making it easy to install, maintain, and replace. It is also designed with overcurrent protection, which helps ensure that the system does not become overloaded, and thereby helps to prevent damage to the device itself. Additionally, the ER3R-100J3PB can be used in conjunction with other medium-voltage disconnect switches to provide additional levels of safety and reliability.

The working principle behind the ER3R-100J3PB utilizes a double-break contact energized coil system that allows for two separate break points within the same device. This allows for the efficient transfer of power between both poles of the device and prevents arcing and sparking between the contacts. Additionally, the self-engerizing coil system provides an additional level of protection against overload. This is important in critical applications, as it helps to ensure the reliability and safety of the system.

The ER3R-100J3PB is an ideal solution for medium-voltage applications that require a reliable disconnect switch. With its hermetically sealed stainless steel enclosure, adjustable limit switch, and its double-break contact energized coil system, it provides excellent protection against the elements and reliable load isolation in a wide variety of industries. Additionally, its easy installation, maintenance, and replaceability makes it the perfect choice for both new and retrofit applications.
