INV400 Isolator – reliable power disconnection

The INV400 isolator is a solid and safe solution for disconnecting electrical circuits. Designed by Schneider Electric, this four-pole (4P) isolator with a rated current of 400A is perfect for both industrial and public building installations. Its versatility stems from the possibility of mounting it on a plate, in distribution boards, and frontally.

Functionality and application

INV400 was created to function as a main and repair isolator. It provides safe and visible disconnection of the circuit, which is crucial during maintenance or repair work. Thanks to the high value of the rated continuous current (Iu 400A) and resistance to short-circuit currents (Icw 20kA), it is an ideal choice for circuits with high power demand. The ability to operate at a voltage of up to 690V AC further increases the scope of its applications.

• Safety: Ensures effective disconnection of the circuit, minimizing the risk of electric shock during service work.
• Versatility: Possibility of mounting on a plate, in distribution boards and frontally facilitates integration with various types of installations.
• High durability: Designed to operate at high short-circuit currents (150 kA) and 690V AC.
• Convenient operation: Equipped with a long rotating handle with a black control element, providing comfortable and intuitive operation.
• Mechanical lock: It has a locking mechanism that prevents accidental switching on of the isolator during service work.

Construction and parameters

The INV400 isolator is characterized by a solid, fixed construction. The connection of the main contacts is made using screw connections, which ensures a secure and durable electrical connection. It has four switchable auxiliary contacts, which can be used to signal the status of the isolator or control other devices. Compact dimensions (185 mm wide, 205 mm high and 130 mm deep) allow for easy integration with existing installations. The IP40 degree of protection provides protection against touching and ingress of solid objects. The rated operating power for AC-23 at 400V is 200 kW, which confirms its high efficiency.
