A disconnect switch is a critical component of any low-voltage system. The ER3R-200J3PB is a 200 Amp disconnect switch that can provide reliable switching and electrical isolation of an electrical circuit. It is often used in a variety of applications, including industrial, commercial, and residential installations.

The ER3R-200J3PB disconnect switch is a three-pole device that provides an efficient and cost-effective way to switch a system off and on. It features a wide voltage range of up to 600 VAC and a frequency range of 0 Hz to 600 Hz, making it suitable for a wide variety of applications. The switch is UL listed and CSA certified for use in hazardous locations, providing superior protection in application settings where high levels of safety are essential. It is also UL listed for arcing fault circuit interruption (AFCI) applications.

The switch is designed to be used in a wall or back box mount configuration, allowing it to be easily installed in a variety of locations. It features quick-connect terminals and pluggable terminations for easy installation. The terminal screws are also designed to accept Type MTW and Type TEW wire, making it easy to connect multiple wires to the switch.

The construction of the ER3R-200J3PB disconnect switch is designed to withstand a wide range of temperatures and environments. Its die-cast aluminum base is corrosion-resistant and features a polyester powder-coated finish for superior protection against harsh conditions. The contacts are made of copper, allowing for high current capacity and superior heat transfer. The internal components are made of high-strength thermoplastic and copper for superior durability.

The working principle of the ER3R-200J3PB disconnect switch is based on simple electrical principles. When the switch is turned on, the contacts inside the switch are activated and current passes through them. This creates a magnetic field that causes the switch to close, allowing current to flow. When the switch is turned off, the contacts open and the magnetic field dissipates, causing the switch to open, thus interrupting the current.

The ER3R-200J3PB disconnect switch can be used in a variety of applications such as motor disconnects, motor control centers, transfer switches, panel meters, and many other low-voltage systems. It is also ideal for applications where safety and reliability are paramount. The switch is designed to provide superior performance in the harshest of environments and is UL listed for AFCI applications.
