ER4P-200N3PB

An ER4P-200N3PB is a three-pole manually operated common toggle disconnect switch and can be used to control and protect low voltage (800VAC or less) currents and circuits. This disconnect switch is mainly used for industrial automation, electric power distribution and other applications.

Application

The ER4P-200N3PB disconnect switch is designed for branch circuit protection in a variety of low voltage applications, including industrial automation, electric power distribution control, safety and other industrial wiring applications. It has ratings for use up to 400A, 1,000V AC/DC, UL approved, cubelet contactors, 3-pole operation, and is constructed with operate/animation features for increased backup protection.

This disconnect switches features a unique automatic interlocking mechanism that allows it to be locked in a closed position when manually operated. This helps to prevent accidental contact with the contacts, reducing the chance of electrical shock or damage. It is also UL certified for a variety of industrial wiring applications.

Working Principle

The working principle of the ER4P-200N3PB disconnect switch is relatively simple. The disconnect switch is operated via a toggle switch, which moves the contact points of the circuit breaker. When the circuit breaker is closed, electricity flows through the switch, allowing current to flow into the connected circuit. When the switch is open, the circuit breaker is released, breaking the current flow, thereby preventing any electrical accidents.

In addition, the switch also features an automatic interlocking mechanism that prevents the switch from being accidently opened while in the closed position. This ensures that the switch is always in the closed position when it is manually operated, thus providing maximum safety.

The ER4P-200N3PB disconnect switch is designed to be both reliable and cost-effective, making it an ideal choice for low voltage applications. It is easy to install and provides excellent protection for your electrical circuits. With its superior performance, it is sure to be your preferred disconnect switch for years to come.
