Modular surge arrester ETITEC ML T123 300/12,5 1+0 002440661

Surge protector – reliable installation protection

This ETITEC ML T123 300/12.5 1+0 modular surge protector is a key element in protecting electrical installations from the effects of overvoltage. Designed for mounting on a TH-35 mm DIN rail, it provides protection against both switching surges and atmospheric discharges. This is a Class 1+2 device, which means it offers comprehensive protection, combining the features of Type 1 and Type 2 surge protectors.

Construction and application

This surge protector has been designed with versatility in mind. It will work in installations with a rated voltage of 240 V and a maximum continuous AC working voltage of 300 V. Its compact design – occupying only 1 module – allows for easy installation even in crowded switchboards. The impulse current of 12.5 kA guarantees effective dissipation of surge energy, protecting connected devices. Optical signaling of the device status facilitates quick identification of any damage.

Key features and benefits

• Versatility: The surge protector meets the requirements for TN, TN-C and TN-S networks, making it an ideal solution for various installations.
• High efficiency: Rated discharge current 8/20μs at 20 kA and maximum discharge current 8/20μs of 40 kA provide effective protection against surges.
• Safety: Protection level of 1.5 kV minimizes the risk of damage to connected devices.
• Practical solutions: The possibility of connecting wires with a cross-section of up to 35 mm² (solid) or 25 mm² (stranded) ensures compatibility with various types of cabling.
• Energy absorption: Specific energy at 39 kJ/Ohm indicates the ability to absorb large surges without damage.
• Durable construction: Made of high-quality varistors, which guarantees reliable operation for a long time.
• Easy diagnostics: Optical indication of the device status allows for quick detection of varistor damage (red – damaged, green – working).
• Compliance with standards: The device meets appropriate safety and quality standards, ensuring safe operation.

The ETITEC ML T123 surge protector is an investment in the safety and reliability of your electrical installation – both for professional installers and end users. It provides peace of mind and minimizes the risk of costly failures caused by surges.
