DPX3-I 160 Isolator Switch – Reliable Power Disconnection

DPX3-I 160 isolator switch is a three-pole device designed for safely disconnecting electrical circuits. It finds application in both industrial installations and public buildings, providing effective isolation and protection against accidental switching during maintenance or repair work. The construction based on proven Legrand technology guarantees high reliability and long service life.

Functionality and Application

DPX3-I 160 is a versatile device that can function as a main, safety, or maintenance isolator switch. It has built-in auxiliary contacts (normally open, normally closed, and changeover), allowing integration with control and signaling systems. Thanks to the possibility of mounting on a TH35 rail or directly on a plate, the switch can be easily adapted to different switchboard configurations. With a locking mechanism, it provides additional safety, preventing accidental opening of the circuit under load.

• Safety first: The safety isolator function allows for complete isolation of the circuit during maintenance or repair work.
• Versatility: It can be used as a main, maintenance, or emergency isolator switch, adapting to the needs of the installation.
• Easy installation: The possibility of mounting on a TH35 rail or directly on a plate facilitates installation and integration with existing infrastructure.
• Status indication: Built-in auxiliary contacts allow monitoring of the switch status and integration with control systems.
• Durability and reliability: Solid construction and high-quality materials ensure long-term trouble-free operation.

Technical Parameters and Construction

The DPX3-I 160 isolator switch is characterized by a continuous rated current of 160A and a short-circuit withstand capacity of up to 1.7 kA. It can operate in circuits with a rated voltage from 220 to 690V AC. Made of high-quality materials, it has an IP30 degree of protection on the front, providing protection against accidental contact. The connection of the main contacts is made using screw connections, guaranteeing a secure and durable connection of the wires. Additionally, an optional overcurrent release increases the functionality of the device, allowing it to be adapted to the specific requirements of the installation. The rated operating power for AC-23 at 400V is 64 kW. The device has a fixed mounting structure, ensuring stability and safety of use.
