Schneider Electric 31101 switch disconnector INS250 4-pole 100 A 690 V AC/DC lever black content_copy

The ComPacT INS disconnect switch from the ComPacT series by Schneider Electric is a 4-pole switch designed for use in industrial electrical installations. It is intended for the safe disconnection of electrical circuits and is suitable for isolation according to standards IEC 60947-1 and IEC 60947-3. The mechanical design ensures that the position of the rotary handle always reflects the actual position of the main switch, enabling safe operational monitoring. The disconnect position corresponds to position O (OFF), and it is not possible to lock the drive in OFF when the switch is open. This ensures the reliability of disconnection and prevents incorrect operation. The switch is designed for use categories AC21A, AC22A, and AC23A, qualifying it for various industrial applications.

Applications

The disconnect switch is designed for use in industrial installations where safe and visible disconnection of power supply is required. It is suitable for applications with alternating and direct voltage, with a rated operational voltage of 250 V DC and 690 V AC at 50/60 Hz. The rated insulation voltage is 800 V AC, ensuring high safety at high voltages. The maximum power is, for example, 55 kW at 660/690 V AC, making it suitable for powerful drives and machine installations. The operating temperature ranges from -25 °C to 70 °C, allowing use in various environments.

Functions and Equipment in Detail

The switch features a direct front-mounted rotary handle in black, which facilitates operation and visually indicates the switch position. The contact position indicator allows the state of the switch (on or off) to be recognized at any time. Although no visible break is present, disconnection is securely ensured by the mechanical design. The protection class IP40 protects against contact with solid objects larger than 1 mm and against splashing water, making the switch suitable for use in enclosed switchgear. The protection class IK07 corresponds to protection against mechanical impacts, such as blows from a tool, and is defined according to EN 50102.

Technology Explained Simply

The switch is designed for conventional thermal current loading of 100 A at 60 °C, which describes the maximum current strength it can withstand continuously. The rated short-circuit making capacity is 30 kA at 690 V AC when operated alone, and increases to 330 kA when combined with a preceding circuit breaker. The rated short-time withstand current is defined according to IEC 60947-3 and, for example, amounts to 8.5 kA for 1 second. The mechanical life is 15,000 cycles, and the electrical life is 1500 cycles at various voltages and load categories. These values ensure high operational safety and longevity.

Compatibility and Accessories

The disconnect switch is designed for fixed mounting on a panel or rail and features a connection pitch of 35 mm. Suitable accessories include, for example, the rotary handle 31057, auxiliary switches such as 29452, terminal covers such as LV429516, and locking devices such as 31073. These components enable functional expansion, such as integration into control systems or mechanical locking.

Mounting and Installation

Mounting is carried out on a rail or panel, with a standardized connection pitch of 35 mm. Dimensions are 140 mm width, 136 mm height, and 96 mm depth. Installation must be performed by qualified personnel, strictly adhering to safety regulations, such as disconnecting the power supply and using voltage detectors. The ambient temperature during storage may range from -50 °C to 85 °C, enabling flexible storage.

Advantages in Operation

The disconnect switch offers high operational safety through the mechanical linkage between drive and main switch. The clear indication of contact position and high service life reduce maintenance requirements and downtime. Compatibility with various accessories allows flexible adaptation to specific requirements. Certifications CCC and KEMA-KEUR, along with compliance with standards IEC 60947-1 and IEC 60947-3, guarantee the quality and safety of the device. The operating temperature range of -25 °C to 70 °C makes the switch suitable for a wide range of operating conditions.
