Surge arrester T2 (C) ETITEC C T2 275/20 4+0 002440395

Protection of electrical installations with ETITEC surge arrestors

The ETITEC C T2 275/20 4+0 surge arrester is a key element in protecting electrical installations from the effects of lightning strikes and overvoltages in the network. The device is designed to protect electrical equipment in residential and commercial buildings, ensuring safe and reliable operation. Installing a surge arrester is an investment in peace of mind and avoiding costly repairs.

Construction and application

This arrester, mounted on a TH-35 mm DIN rail, occupies 4 modules. It is a Type 2 (Class T2) device according to PN-EN 61643-11, which means it effectively dissipates the impulse energy generated by lightning strikes or other disturbances in the network. The rated discharge current of 20 kA (8/20) guarantees high protection efficiency. The arrester signals its operation optically, making diagnosis and rapid response easier in the event of an overvoltage. Designed for use with TN networks, it provides comprehensive protection for electrical installations.

Key features and benefits

• High protection efficiency: Rated AC voltage of 230V and a protection level of 1.5 kV provide effective protection against overvoltages.
• Versatility: Designed for residential and commercial installations in TN network systems.
• Optical signaling: Allows quick identification of the device status and the need for replacement after operation.
• Easy installation: Mounting on a standard TH-35 mm DIN rail simplifies installation and integration with existing electrical infrastructure.
• Large wire throughput: Maximum wire cross-section of 35 mm² (solid/stranded) and 25 mm² (flexible) allows connection of wires of different thicknesses.
• Compliance with standards: Meets the requirements of the latest PN-EN 61643-11 standard, guaranteeing safety and reliability.
• Compact dimensions: Occupies only 4 modules, allowing it to be easily placed in a distribution board.

The protection level is 1.5 kV, the highest permanent operating AC voltage is 275 V, and the rated discharge current (8/20) reaches 20 kA. The device operates at a rated AC voltage of 230 V and occupies 4 modules in the distribution board. It is intended for TN network systems.

Remember that proper selection and installation of a surge arrester should be performed by a qualified electrician to ensure maximum protection of the electrical installation.
