The ComPacT INS isolator switch from the ComPacT series by Schneider Electric, type 31105, is a 4-pole switch designed for use in industrial and commercial electrical installations. It is intended for the safe disconnection of electrical circuits and is designed for insulation function in accordance with standards IEC 60947-1 and IEC 60947-3. The mechanical design ensures that the position of the front rotary handle always reflects the actual position of the main switch. The disconnection position corresponds to position O (OFF), and the drive is not capable of indicating the OFF position when the switch is open. Locking in the OFF position is also not possible when the switch is open. Supported usage categories include AC21A, AC22A, and AC23A, enabling use in various applications.

Applications
This switch is designed for use in electrical installations with operating voltages up to 690 V AC and 250 V DC. It is suitable for applications requiring safe and visible disconnection of power supply, such as machine controls, drive technology, or maintenance of electrical equipment. The rated insulation voltage is 800 V AC, ensuring high safety at high voltages. The maximum power varies depending on voltage, reaching up to 110 kW at 500/525 V AC or 90 kW at 660/690 V AC.

Functions and Equipment in Detail
The switch features a direct front rotary handle in black, enabling simple and secure operation. The contact position indicator shows the current position of the switch. The rated short-circuit making capacity is 30 kA at 690 V AC, and 330 kA can be achieved when a preceding power circuit breaker is present. The rated short-time withstand current is defined according to IEC 60947-3 and includes values such as 8.5 kA for 1 second. The mechanical life is 15,000 cycles, while the electrical life is 1,500 cycles for various load categories.

Technology Explained Simply
The switch is designed for fixed installation and can be mounted either on a rail or on a plate. The connection pitch is 35 mm, enabling standard installation in enclosures. Connections are located on the front side, ensuring a compact and clear installation. The protection rating IP40 protects against finger contact and ingress of solid foreign objects larger than 1 mm, while the protection rating IK07 provides protection against mechanical impacts such as shocks or vibrations. The operating ambient temperature ranges from -25 °C to +70 °C, and the storage temperature ranges from -50 °C to +85 °C.

Compatibility and Accessories
Various accessories are available for this isolator switch, extending its functionality. These include mechanical interlocks (e.g. 31073), terminal covers (e.g. LV429516), auxiliary switches (e.g. 29450), and extended rotary handles (e.g. LV431050). These components allow adaptation to specific requirements such as additional safety functions, improved accessibility, or integration into control systems.

Mounting and Installation
Mounting is fixed onto a rail or plate. Dimensions are 140 mm width, 136 mm height, and 96 mm depth. Installation must be carried out by qualified personnel, observing safety regulations such as disconnecting the power supply, locking the switch in the disconnection position, and using voltage detectors to verify the absence of voltage.

Advantages in Operation
The switch offers high reliability due to its long mechanical and electrical life. The clear indication of contact position and mechanical interlocking of positions increase safety. Compatibility with various accessories allows flexible adaptation to different requirements. Compliance with standards IEC 60947-1 and -3, as well as certifications KEMA-KEUR and CCC, guarantee the quality and safety of the product.
