Surge arrester T1, T2 (B, C) - leakage current free ETITEC SM T12 300/25 4+0 RC 002440573

Electrical installation protection with ETITEC SM T12 300/25 4+0 RC

This class 1+2 surge protector, designated as T1 and T2 (B, C), is a key element ensuring electrical safety in buildings and installations. Designed to work with TN-S network systems, it effectively protects against the effects of lightning strikes and overvoltages in the power grid. A leakage current-free design minimizes the risk of unwanted interference with device operation.

The ETITEC SM T12 300/25 4+0 RC surge protector is distinguished by its high efficiency, confirmed by parameters such as a surge current of 25 kA (10/350 µs) and a protection level of 1.5 kV. The use of MOV and GDT technology guarantees reliable protection of sensitive electronic devices. Optical indication of the device's status and a signaling contact inform about any damage, enabling a quick response and replacement.

Key features and benefits:

• Versatile application: The surge protector is designed for TN-S network systems, providing optimal protection in typical building installations.
• High performance: A surge current of 25 kA and a protection level of 1.5 kV guarantee effective protection against overvoltages.
• Safety of use: The absence of leakage current minimizes the risk of interference with device operation and provides additional safety.
• Convenient signaling: Optical status indication and a signaling contact facilitate monitoring device operation and quick identification of any failures.
• Easy installation: The design for mounting on a TH-35 mm DIN rail ensures simple and quick installation in electrical distribution boards.
• Energy absorption: Specific energy at 156.2 kJ/Ohm allows for absorbing large surges without damaging the device.
• Solid construction: A housing with an IP20 degree of protection provides protection against touch and dust.

The ETITEC SM T12 300/25 4+0 RC surge protector is a reliable solution for installers and users looking for comprehensive protection against overvoltages in electrical installations. Its compact size (8 modules) allows for easy adaptation to existing distribution boards, and high-quality workmanship guarantees long-lasting and trouble-free operation. The maximum wire cross-section of 35 mm² ensures compatibility with various types of installation wires, both solid and stranded.
