The article 31319 from Schneider Electric is an Interphase Barrier accessory, specifically designed for use with disconnectors from the ComPacT INS and ComPacT INV product families. This component serves as isolation accessory and is used in 4P installations to ensure safe electrical separation between individual phases. The delivery is made as a set of 6 units, with each unit intended for installation in a 4-pole disconnector. The barrier is part of the mechanical safety architecture, ensuring that the position of the drive always reflects the actual position of the main switch. The disconnect position corresponds to position O (OFF), and it is not possible to lock the drive in OFF position when the switch is open. This ensures a clear and safe operational indication.

Applications

The interphase barrier is used in industrial and commercial electrical installations where safe and reliable separation of electrical conductors is required. It is specifically designed for disconnectors of the ComPacT INS/INV series, used in installations with a rated voltage up to 690 V and a rated current up to 2500 A. The use is in installations complying with standards IEC 60947-1 and IEC 60947-3, covering usage categories AC21A, AC22A, and AC23A. These categories define the operating conditions for disconnectors in terms of load type and switching operations.

Functions and Equipment in Detail

The barrier consists of a set of six units, each to be installed in a 4-pole disconnector to ensure electrical isolation between individual phases. The mechanical design of the ComPacT switches ensures that the drive indication always matches the actual state of the main switch. The disconnect position is indicated by position O (OFF), and it is not possible to lock the drive in OFF position when the switch is open. This prevents misoperation and increases operational safety.

Technology Explained Simply

The interphase barrier is an insulating component placed between individual phases of a 4-pole disconnector. Its function is to ensure electrical separation, preventing short circuits or unintended current flows between phases. The barrier is made of a non-conductive material with the required insulation strength. Installation takes place within the switch, with positioning ensuring that the electrical contacts of individual phases are separated. Use in conjunction with ComPacT INS/INV series disconnectors ensures conformant and safe separation according to applicable standards.

Compatibility and Accessories

The interphase barrier is exclusively intended for disconnectors from the ComPacT INS and ComPacT INV product families. It is designed as 4P isolation accessory and used in installations with 4-pole switches. Use with other switch types is not intended and not recommended.

Installation and Mounting

Mounting takes place within the disconnector, with the six barrier units positioned according to the phase arrangement in the switch. Installation requires no additional tools or components, and the units are directly inserted into the designated holders. The mechanical design of the ComPacT switches ensures that the drive position always reflects the position of the main switch, supporting correct mounting and function of the barrier.

Operational Advantages

The interphase barrier increases safety in electrical installations by ensuring reliable electrical separation between phases. Use in conjunction with ComPacT INS/INV series disconnectors ensures conformant and safe separation according to standards IEC 60947-1 and IEC 60947-3. The clear indication of switch position via the drive prevents misoperation and enhances operational safety. The warranty is 18 months, underscoring the product’s reliability.
