Schneider Electric 31180 switch disconnector INV100 3-pole 100 A 690 VACDC lever red base yellow content_copy

The Compact INV100 switch disconnector from Schneider Electric is a non-automatic 3-pole switch from the ComPacT series, designed for use in industrial and commercial electrical installations. It is used for the safe disconnection of electrical circuits and enables the isolation of circuits during operation. The switch features a red rotary handle and a yellow front, making it visually clearly identifiable. The visible disconnection point ensures unambiguous confirmation of the open state, which is crucial for maintenance and inspection work.

Applications

The Compact INV100 is designed for use in installations with alternating and direct voltage. The rated operational voltage is 690 V AC at 50/60 Hz and 250 V DC, making it suitable for a wide range of industrial applications, such as machine building, material handling technology, or power supply. The insulation capability is confirmed, so the switch can be used for safe disconnection of circuits during maintenance work or in emergencies.

Functions and Equipment in Detail

The switch features a contact position indicator that visually signals the current state (on or off). The visible disconnection point allows for safe verification of the open state, supporting compliance with safety regulations in electrical operation. The handle color red is standard, making the switch easily identifiable. The front is yellow, contributing to better visibility in the installation. Mounting is fixed on a rail or plate, with a connection pitch of 45 mm. Connections are located on the front side, both top and bottom.

Technology Explained Simply

The switch is designed for a rated insulation voltage of 800 V AC, ensuring high electrical strength. The rated impulse voltage withstand is 8 kV, making it suitable for use in environments with transient voltage surges. The conventional thermal current is 100 A at an ambient temperature of 60 °C, describing the thermal load capacity under realistic operating conditions. The rated short-circuit making capacity is 30 kA when operated alone, and 330 kA when combined with a preceding circuit breaker. The rated short-time current withstand is 8.5 kA for 1 second, describing the switch’s ability to handle short-term overloads. The mechanical life is 15,000 cycles, and the electrical life is 1,500 cycles for various load types (AC-22A, AC-23A, DC-22A, DC-23A). The maximum power is, for example, 55 kW at 690 V AC, highlighting its suitability for high-performance installations.

Compatibility and Accessories

The Compact INV100 can be combined with various accessories to adapt functionality to specific requirements. These include, for example, rotary handles in different versions (such as the 31057 right-hand black rotary handle), mechanical interlocks (31073), auxiliary switches (29452, 29450) for signal transmission to controls, connection extenders (LV431563), and terminal covers (LV429516, LV429518) to improve safety. Combining it with phase barriers (LV429329) enables more precise control and monitoring of power distribution.

Mounting and Installation

Mounting is fixed on a rail or plate, with a connection pitch of 45 mm. The device dimensions are 140 mm (width), 136 mm (height), and 96 mm (depth). The operating ambient temperature ranges from -25 °C to 70 °C, and the storage temperature ranges from -50 °C to 85 °C. The protection class IP40 protects against contact with solid objects larger than 1 mm and against splashing water, making it suitable for use in enclosed switchgear. The protection class IK07 corresponds to protection against mechanical impacts up to 20 J, ensuring high mechanical robustness. The standards IEC 60947-3 and IEC 60947-1 are met, confirming compliance with international standards. The certifications CCC and KEMA-KEUR underline the quality and safety of the product.

Advantages in Operation

The Compact INV100 offers high reliability due to its robust construction and long service life. The visible disconnection point and contact position indicator increase operational safety and simplify maintenance. The high short-circuit withstand and insulation capability make it a reliable component in complex power supply systems. The combinability with various accessories allows flexible adaptation to different requirements. Mounting is simple and performed on standard rails or plates, facilitating integration into existing installations. The operating temperature ranges and protection classes make the switch suitable for a wide range of operating environments, from indoor installations to industrial environments with increased mechanical stress.
