Product Description

The AC400V Fuse Power Switch Hr17 160 is a robust and reliable electrical switch designed for emergency power circuit protection in high-current applications. Also known as a knife switch, it features a simple yet effective design with a blade-style contact that manually disconnects the circuit when operated. The switch is equipped with fuses that provide overcurrent protection, ensuring that the circuit is safely interrupted in case of a fault.

Rated for AC 400V and a maximum current of 160A, this switch is suitable for use in industrial, commercial, and utility applications where a reliable and visible means of disconnecting the power is required. It has a sturdy construction with high-quality materials that can withstand harsh environmental conditions, including high temperatures and mechanical stress. The switch is designed for panel mounting, with a clear handle that indicates the on/off position, providing a visual confirmation of the circuit status.

Features

Emergency Disconnect: Allows for quick and easy manual disconnection of the power supply in case of emergencies or maintenance, ensuring safety for personnel and equipment.

Over-current Protection: Integrated fuses protect the circuit from excessive current, preventing damage to the switch and connected equipment.

High Voltage and Current Rating: Rated for AC 400V and 160A, making it suitable for high-power applications.

Visible Contact Position: The blade-style design provides a clear visual indication of whether the switch is in the on or off position.

Sturdy Construction: Built with durable materials to withstand harsh environments, ensuring long-term reliability and performance.

Easy Installation: Designed for panel mounting, with simple wiring connections and clear installation instructions.

Application

This fuse power switch is widely used in industrial power distribution systems, motor control centers, generator sets, and other high-power applications where a reliable emergency disconnect is essential. It is commonly used in factories, construction sites, substations, and utility plants to isolate circuits during maintenance, repair, or in case of an emergency. The visible contact position makes it ideal for applications where a clear indication of the circuit status is required for safety purposes. The integrated fuses provide an additional layer of protection, making it suitable for circuits that are prone to overcurrent conditions, such as those with inductive loads or occasional current surges.

Faq

Q: What type of fuses does the switch use?

A: The switch is designed to use standard bolted or plug-in fuses of the appropriate rating, depending on the model. Please refer to the product specifications for the exact fuse type and rating.

Q: Can it be used in DC circuits?

A: No, this switch is specifically designed for AC circuits operating at 400V. For DC applications, a different type of switch suitable for DC voltage should be used.

Q: Is the switch waterproof?

A: While the switch has a sturdy construction, it is not fully waterproof. It is suitable for use in dry or protected environments. For wet or outdoor applications, a weatherproof enclosure should be used.

Q: How often should the fuses be replaced?

A: Fuses should only be replaced if they have blown due to an overcurrent event. It is recommended to use fuses with the same rating as specified by the manufacturer.

Q: Can the switch be operated under load?

A: No, this is a knife switch designed for off-load operation. It should only be used to disconnect the circuit when there is no current flowing, to prevent arcing and damage to the contacts.
