Surge arrester T1, T2 (B, C) - leakage current free ETITEC SM T12 300/12,5 4+0 RC 002440547

Electrical installation protection with ETITEC SM T12

This surge protector of class 1+2, designated as T1 and T2 (B, C), is a key element in protecting the electrical installation from the effects of lightning strikes and surges. The ETITEC SM T12 300/12.5 4+0 RC model is designed to effectively protect TN-S networks, ensuring safety for both devices and users. Its construction based on a combination of a varistor and a spark gap guarantees a quick and reliable response to sudden voltage changes.

Construction and application

This surge protector is mounted on a DIN TH-35 mm mounting rail and occupies 4 modules. It is intended for protection against surges in installations with a rated voltage of 240V and a maximum continuous AC operating voltage of 300V. An integrated signaling contact (optical) informs about the device's operation, which facilitates quick problem identification and appropriate action. Thanks to the possibility of connecting wires with a cross-section of up to 35 mm², the surge protector can protect a wide range of circuits.

Key features and benefits

• High protection efficiency: Impact current at 12.5 kA and specific energy of 39 kJ/Ohm provide effective protection against damage caused by surges.
• Versatile application: Surge protector designed for TN-S networks, making it an ideal solution for residential, commercial and industrial buildings.
• Status indication: Built-in signaling contact facilitates monitoring of the device status and quick response in case of failure.
• Safety: Protection level of 1.5 kV minimizes the risk of damage to connected devices.
• Solid construction: Made of high-quality materials guarantees durability and reliable operation for a long time.
• Easy installation: Mounting on a standard DIN TH-35 mm rail makes installation simple and quick.
• Universality: The possibility of connecting wires with a cross-section of up to 35 mm² ensures compatibility with various types of electrical installations.
