This switch is rated for up to 16 amps of continuous duty, with a dielectric voltage rating of up to 250 volts.

ER4P-16N3PB Application Field

The ER4P-16N3PB is suitable for use in a variety of residential and commercial applications. It can be used as a main disconnect switch for a building, or as a secondary disconnect switch for specific equipment, such as HVAC units, pool pumps, or securely isolating heavy-duty power tools. The ER4P-16N3PB is also suitable for use as a circuit breaker in certain applications, such as protecting a specific circuit from overloads.

ER4P-16N3PB Working Principle

The ER4P-16N3PB disconnect switch uses a manual disconnecting means to allow technicians to safely turn on and off electrical systems without having to go to a power source. The switch is activated by a simple push-button operation, which instantly closes the contacts and locks them in the closed position until the button is released. This makes it easy to both disconnect and reconnect power to a piece of equipment that needs servicing.

When the button is pressed, the contacts of the switch are forced together using a springloaded mechanism. This mechanism provides a redundant fail-safe connection, meaning that when the contacts are forced together, they will remain locked in place until the button is released. This ensures that the power will stay off until the service technician is ready to reconnect the power source.

The ER4P-16N3PB has several safety features that make it one of the most user-friendly disconnect switches on the market today. The device is ignition protected and has VDE approvals for use in wet locations, making it ideal for outdoor applications. Additionally, the switch is designed to fail to the off position in the event of a power surge or failure of the mechanism. This increases the safety of the device by preventing accidental reconnection of the power source.

Conclusion

The ER4P-16N3PB is a UL approved manual disconnect switch suitable for residential or commercial applications. It has an incredibly lightweight yet powerful design that provides reliable safety and power disconnection in a variety of situations. The robust construction, certified ratings, and built-in safety features make this device a very reliable and excellent choice for any disconnect switch applications.
