Schneider Electric 31113 switch disconnector INS500 4-pole 500 A 690 V AC/DC lever black content_copy

The load disconnector ComPacT INS from the ComPacT series by Schneider Electric is a 4-pole, non-automatic switch with a rated current of 500 A. It is designed for the safe disconnection of electrical installations during operation and enables the isolation of circuits, with the suitability for isolation explicitly confirmed. The switch is rated for operating voltages up to 690 V AC (50/60 Hz) and 250 V DC, making it suitable for applications in industrial and commercial electrical installations. The rated insulation voltage is 800 V AC, ensuring high electrical strength. The rated impulse voltage withstand is 8 kV, complying with IEC 60947-3, protecting the switch against transient voltage surges.

Applications

The load disconnector is used in industrial distribution systems where a safe and visible disconnection of power supply is required. It is suitable for installations with high thermal and mechanical loads, particularly in environments with pollution degree 3, i.e., in rooms with increased dust or moisture exposure. The operating ambient temperature ranges from -25 °C to +70 °C, enabling use in industrially variable climate conditions. The storage temperature ranges from -50 °C to +85 °C, allowing flexible storage even under extreme conditions.

Functions and Equipment in Detail

The switch features a direct front-mounted black rotary handle, enabling simple and secure operation. The contact position indicator is integrated, allowing visual verification of the operating state (on/off). A visible break is not present, meaning the contact disconnection is not visually verifiable, although the isolation function is technically guaranteed. The maximum power varies depending on the operating voltage, ranging from 132 kW to 500 kW, with values specified for different voltage ranges (e.g., 220/240 V AC up to 690 V AC). The rated power is uninterrupted, indicating continuous operational capability without interruption.

Technology Explained Simply

The switch is designed for use in AC and DC networks, with a network frequency of 50/60 Hz. The rated short-circuit making capacity is 330 kA when a preceding power circuit breaker is present, and 50 kA when the load disconnector is used alone. 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, while the electrical life is 1500 cycles for AC-22A and AC-23A, and 1000 cycles for DC-23A. The connection pitch is 45 mm, enabling standard mounting in enclosures.

Compatibility and Accessories

The load disconnector is designed for mounting on rails or plates, allowing flexible integration into existing enclosure constructions. Available accessories include auxiliary switches (e.g. 29452, 29450), terminal covers (e.g. LV432592, LV432594), door couplings (31052), phase separators (LV432570), mechanical interlocks (31074), and connection extenders (LV432490). These components enhance functionality, e.g. for integration into control systems or to improve safety.

Mounting and Installation

Mounting is fixed onto rails or plates. Connections are located on the front side, both top and bottom, enabling easy wiring. The protection rating IP40 protects against finger contact and solid foreign objects, but not against water. The protection rating IK07, according to EN 50102, protects against mechanical impacts such as shocks or vibrations. Installation and maintenance must only be carried out by qualified electrical specialists, adhering to safety regulations (e.g. NFPA 70E, CSA Z462). Before work, the entire power supply must be switched off, the switch moved to the disconnection position, and checked with an appropriate voltage detector.

Advantages in Operation

The load disconnector offers high reliability due to its robust construction and long service life. The integrated contact position indicator allows for quick status verification. Compatibility with various accessories expands application possibilities. Compliance with standards IEC 60947-1 and IEC 60947-3, as well as certifications CCC and KEMA-KEUR, guarantees the quality and safety of the device. The warranty period is 18 months.
