The ComPacT INS disconnect switch from the ComPacT series by Schneider Electric is a 4-pole switch with a fixed mounting mode and a red rotary drive, designed for use in industrial and commercial electrical installations. It provides safe disconnection of electrical circuits in accordance with standards IEC 60947-1 and IEC 60947-3, where the disconnection position corresponds to position O (OFF). The mechanical design ensures that the drive position always reflects the actual position of the main switch, thus preventing incorrect operation. The switch is suitable for usage categories AC21A, AC22A, and AC23A, qualifying it for uninterrupted operating conditions in installations with high loads.

Applications
This disconnect switch is designed for use in electrical distributions and switchgear where safe isolation of circuits is required. It is particularly suitable for installations with a rated voltage up to 690 V AC at 50/60 Hz and 250 V DC. The insulation capability ensures that the switch can be used as a disconnecting device in electrical installations to create a safe working environment for maintenance and repair work. The operating ambient temperature ranges from -25 °C to 70 °C, making the switch suitable for use in demanding climatic environments.

Functions and Equipment in Detail
The switch features a contact position indicator that visually displays the current state of the switch. Operation is performed via a red rotary handle, ensuring clear and intuitive control. Connections are located on the front side, both top and bottom, enabling flexible integration into enclosures. The maximum power rating is 900 kW at 500/525 V AC under AC-23 category, making it suitable for high-power drives and industrial machinery. The mechanical life expectancy is 3000 cycles, indicating high durability and long service life.

Technology Explained Simply
The switch is designed for a rated insulation voltage of 1000 V AC and has a rated impulse voltage withstand of 12 kV, making it suitable for applications with transient voltage surges. The conventional thermal current is 1600 A at 60 °C in free air, describing its thermal load capacity under operating conditions. The rated short-circuit making capacity is 75 kA when operated alone, and increases to 330 kA when combined with a preceding circuit breaker. The rated short-time current withstand, as defined by IEC 60947-3, ranges from 8 kA for 30 s to 50 kA for 0.5 s, indicating the switch’s ability to withstand short-term overload due to short-circuit currents.

Compatibility and Accessories
The disconnect switch can be combined with various accessories to extend its functionality. These include, for example, the phase separator 31315 for the INS/INV series, auxiliary switches such as 29452 with 1 contact for PLC signals, or the spacing spreader 31305 for flat connections. The rotary drive 31288 with door coupling is also compatible and enables mechanical interlocking. Mounting is either on a rail or a plate, with a connection pitch of 70 mm.

Mounting and Installation
Mounting is performed in fixed mounting mode, with the switch secured to a rail or plate. Dimensions are 410 mm width, 300 mm height, and 146.5 mm depth. Installation must be carried out by qualified personnel, strictly following the manufacturer’s safety instructions, particularly regarding de-energizing and locking procedures. The protection class IP40 protects against contact with moving parts and against solid objects, while the protection class IK07 provides protection against mechanical impacts such as shocks and vibrations.

Operational Advantages
The switch offers high reliability due to its mechanical design, which ensures clear indication of the switch position. The high short-time current withstand and high making capacity make it suitable for demanding industrial applications. The integrated contact position indicator and clear operation via the red rotary handle facilitate maintenance and servicing. Compatibility with various accessories allows flexible adaptation to specific installation requirements. The operating temperature range of -25 °C to 70 °C enables use in a wide range of environments, from air-conditioned rooms to industrial halls.
