Schneider Electric 31175 switch disconnector INV630 4-pole 630 A 690 VACDC lever black content_copy

The ComPacT INV load disconnector from the ComPacT series by Schneider Electric is a 4-pole switch with a rotary drive, designed for the disconnection of electrical installations in accordance with standards IEC 60947-1 and IEC 60947-3. It is intended for the safe disconnection of loads and provides a visible disconnection position indicated by the position O (OFF). The mechanical design ensures that the drive position always corresponds to the actual position of the main switch. This prevents incorrect operation, as the actuated drive cannot indicate the OFF position if the switch is open. Locking in the OFF position is also impossible if the switch is not actually open, thereby increasing operational safety.

Applications

The switch is designed for use in industrial and commercial electrical installations where safe and visible disconnection of power supply is required. It is suitable for applications with alternating and direct voltage (AC/DC) and is used in switchgear, distribution systems, and machine controls. The usage categories AC21A, AC22A, and AC23A define the operating conditions for load disconnectors in various installation configurations.

Functions and Equipment in Detail

The load disconnector features a contact position indicator that visually displays the current state of the switch. The visible disconnection point (visible break) allows for clear confirmation that the power supply has been interrupted. The handle color is black, and the control type is a rotary handle, ensuring clear and precise operation. The suitability for isolation is provided, meaning the switch can be used for the safe disconnection of electrical installations.

Technology Explained Simply

The switch is designed for a rated operating voltage of 690 V AC (50/60 Hz) and 250 V DC. The rated insulation voltage is 800 V AC, and the rated impulse voltage withstand is 8 kV. The conventional thermal current in free air is 630 A at an ambient temperature of 60 °C. The rated short-circuit making capacity is defined as 330 kA (with a preceding power circuit breaker) and 50 kA (standalone). The rated short-time current withstand is 11.5 kA for 3 seconds, 20 kA for 1 second, 4 kA for 30 seconds, and 4.9 kA for 20 seconds, according to IEC 60947-3. The mechanical life is 10,000 cycles, ensuring high operational reliability over a long period.

Compatibility and Accessories

The switch can be combined with various accessories to meet specific requirements. These include, for example, long terminal covers LV432594, connection extensions LV432490, phase separators LV432570, auxiliary switches such as 29452 (1 contact, 5 A, 380/440 V AC) or 29450 (various contact variants), mechanical interlocks (31074), and door couplings (31052). These components allow for application-specific adaptation of the switch to the respective switchgear.

Mounting and Installation

The load disconnector is designed for fixed mounting and can be mounted either on a plate or on a rail. Connections are located on the front side, both top and bottom. The connection pitch is 45 mm. The dimensions of the device are 185 mm (width), 205 mm (height), and 120 mm (depth). Mounting is in accordance with standards IEC 60947-1 and IEC 60947-3. The protection rating IP40 (according to IEC 60529) protects against finger contact and against ingress of solid foreign objects larger than 1 mm. The protection rating IK07 (according to EN 50102) provides protection against mechanical impacts, such as blows with a tool.

Advantages in Operation

The switch is characterized by high operational reliability, clear operation, and long service life. The visible disconnection position and contact position indicator increase safety during maintenance work. The suitability for isolation and compliance with standards IEC 60947-1 and -3 guarantee reliable performance in industrial applications. The operating temperature range is between -25 °C and +70 °C, enabling broad applicability in various environments. The storage temperature range extends from -50 °C to +85 °C. The product weight is 4.9 kg, and the packaging unit contains one device. The warranty is 18 months.

The maximum power is up to 560 kW at 660/690 V AC, depending on the voltage level, highlighting its suitability for high-performance installations. The rated power is continuous, meaning the switch can be operated without interruption of the power supply as long as load limits are not exceeded. The pollution degree 3 indicates that the switch is suitable for environments with increased pollution risk, as commonly found in industrial installations.
