Surge protective device iPFK20-T2-3N 3+1-conductor Type2 20 kA A9L15693

Protection of electrical installations against overvoltage

The iPFK20-T2-3N surge arrester is a safety device protecting electrical installations from the effects of overvoltage, both caused by lightning strikes and induced in the network. The device is designed for mounting on a TH-35 mm DIN rail and provides protection in TN-S and TT network systems. Thanks to its construction and parameters, it reduces the risk of damage to electrical and electronic devices, increasing safety of use.

Construction and application

This arrester is type 2, which means it is used to protect against indirect overvoltage. It has 3 poles plus neutral (3+N), allowing for comprehensive protection of circuits. Optical signaling informs about the operation of the device, making it easier to locate a potential failure. The use of MOV+GDT technology ensures effective protection with simultaneous durability. The maximum wire cross-section of 16 mm² allows connection of wires of different thicknesses, adapting to the needs of a specific installation.

Key features and benefits

• High protection efficiency: Rated discharge current at 20 kA and protection level of 1.1 kV (L-N) and 1.5 kV (N-PE) guarantee effective protection against overvoltage.
• Versatility: Compatibility with TN-S and TT network systems means that these arresters can be used in a wide range of applications – from residential construction to industrial.
• Convenient installation: Mounting on a standard TH-35 mm DIN rail makes installation easier and faster.
• Feedback: Optical indication of operation allows for quick identification of the problem and taking appropriate repair actions.
• Durability: Short-circuit strength at 25 kA ensures resistance to damage during short circuits in the installation.
• Compact dimensions: 4 module size allows for efficient use of space in the switchgear cabinet.
• Safety: Protection class IP20 protects against accidental contact.

The A9L15693 surge arrester is a reliable solution for installers and users looking for effective protection of their electrical devices against the effects of overvoltage. Its versatility, ease of installation and high efficiency make it an ideal choice for both new installations and modernization of existing protection systems.
