Surge arrester T2, T3 (C, D) - with fuse insert ETITEC MF T23 300/20 1+0 002440700

Electrical installation protection with ETITEC MF T23 300/20 1+0

The ETITEC MF T23 surge protector is a reliable element protecting the electrical installation from the effects of sudden voltage surges. Designed for TN, TN-S and TN-C systems, it effectively protects against damage to electrical and electronic devices. It is a class T2 and T3 device, which means it provides protection against both direct and indirect lightning strikes.

Design and application

Designed for mounting on a TH-35 mm DIN rail, the ETITEC MF T23 surge protectors occupy only 1 module, allowing them to be easily integrated into an existing distribution board. It has a built-in fuse, which further increases safety and optically signals the operating status. This allows installers and users to be immediately informed of the need to replace the surge protector after a surge occurs. Designed to protect circuits with a rated voltage of 240V AC and a maximum discharge current of 40 kA (8/20), it will be useful in protecting various types of receivers - from domestic electrical installations to more demanding industrial applications.

Key features and benefits

• High protection efficiency: Rated discharge current of 20 kA (8/20) and a protection level of 1.5 kV guarantee effective protection against overvoltages.
• Versatility: Compatible with TN, TN-S and TN-C networks - a wide range of applications.
• Built-in protection: Integrated fuse provides additional safety and signals the need for replacement after operation.
• Simple installation: Mounting on a standard TH-35 mm DIN rail - quick and easy installation.
• Compact size: Occupies only 1 module - saving space in the distribution board.
• Optical signaling: Allows quick identification of the surge protector status without the need for disassembly.
• Large wire cross-section: Supports wires with a cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible) - possibility of connecting different types of wires.
• Short-circuit strength: Withstands short-circuits with a current of up to 50 kA - ensures safety in the event of a network failure.
