Disconnect switch INS2500 2500A 4P 31341

Disconnect switch for demanding applications

The Compact INS INV disconnect switch, model INS2500, is a robust and reliable device designed for safely disconnecting high-current electrical circuits. Its four-pole design and rated current of 2500A make it an ideal solution for both installers and end-users where high operational reliability and safety are required.

This disconnect switch stands out for its versatile mounting – it can be easily installed on a plate, in a distribution board (4-hole), frontally or indirectly. This makes it suitable for a variety of electrical installation configurations. Made of high-quality materials, it ensures long-lasting and trouble-free operation.

Functionality and application

The device is primarily intended to function as a main and maintenance disconnect switch. It provides effective circuit isolation, allowing for safe maintenance or repair work. The long rotating handle facilitates operation, and the locking mechanism increases safety – preventing accidental circuit closure during service work. Screw connection of the main contacts guarantees a stable and reliable connection of the conductors.

The INS2500 disconnect switch is characterized by high resistance to environmental conditions (IP40 protection class on the front side) and withstands short-circuit currents (rated withstand short-circuit current Icw is 50 kA). The possibility of mounting in distribution boards allows integration with existing electrical infrastructure. Additionally, it has 4 switchable auxiliary contacts, which increase its functionality in more complex control systems.
