Product information

Description

ETI ETITEC SM T12 300/25 3+0 is a three-pole surge arrester designed for combined Type T1/T2 (B, C) protection in low-voltage power systems. The device with nominal parameters 300/25 provides protection against lightning impulses and switching overvoltages and is intended for installation in distribution boards of commercial, industrial and residential buildings. The product is specified as without leak current, making it suitable where residual leakage must be minimized.

Advantages

The ETITEC SM T12 300/25 3+0 offers coordinated T1/T2 protection in a compact three-pole configuration, ensuring fast clamping of high-energy surges while maintaining compatibility with downstream protective devices. Its construction reduces residual leakage current to negligible levels, and the device is made for straightforward mounting in typical distribution boards. The nominal 300/25 rating provides a balance between maximum discharge capability and continuous operating voltage for common low-voltage networks.

Suitable for

Protection of distribution boards in commercial and industrial facilities
Safeguarding sensitive electrical equipment from lightning and switching surges
Use in three-phase low-voltage power systems without neutral leakage requirements
Integration into coordinated surge protection systems at service entrance or sub-distribution level

Key specifications

Poles: 3+0 (three-pole)
Nominal parameters: 300/25

How to use

Install the surge arrester in the incoming or sub-distribution board according to local wiring regulations and ETI installation guidelines. Connect the three phases to the corresponding input terminals and ensure a solid, low-impedance protective earth connection. Verify clearances and coordination with upstream and downstream protective devices; ensure the unit is accessible for inspection and replacement if required. Commission the system after mechanical and electrical checks and confirm that the earthing arrangement meets the required standards for surge protection performance.

Usage recommendations

Place the ETITEC SM T12 300/25 3+0 as close as possible to the main service entrance or the protected sub-distribution board to minimize conductor length between the arrester and the installation earthing point. Combine this device with appropriate follow-on protection devices (Type 2/SPDs) and maintain regular inspection intervals to confirm integrity and functional readiness.
