Disconnect switch INS160 160A 3P 28912

Isolator switch – safety and reliability in one device

This three-pole INS160 isolator switch with a rated current of 160A is a key element of any electrical installation, providing safe and reliable disconnection of circuits. Designed for both industrial and general construction applications, it performs well in power distribution systems, allowing effective power disconnection for maintenance or service work. Solid construction and high-quality workmanship guarantee long-lasting and trouble-free operation.

Construction and functionality

The INS160 isolator switch is distinguished by its universal mounting – it can be installed on a DIN rail or directly on a plate or in distribution boards. It is equipped with an ergonomic, black rotary handle with a locking mechanism, which ensures ease of operation and additional safety. Connection of the main circuit conductors is made using solid screw terminals. The IP40 degree of protection protects against access to hazardous live parts. This makes the switch resistant to the conditions prevailing inside switchboards.

Technical parameters and application

The isolator is characterized by high short-circuit strength parameters – the rated conditional short-circuit current Iq is as high as 65 kA, and the withstood short-time current Icw is 5.5 kA. The rated operating voltage is 690V AC, making it suitable for most standard electrical installations. The device has two switchable auxiliary contacts, which can be used to signal the circuit disconnection status or control other devices. Its construction as a permanently mounted device ensures connection stability and reliability. Additionally, the possibility of complete circuit disconnection confirmed by a certificate makes it ideal as a repair or main switch.
