Surge arrester T2 40kA 1P IT-440V 412230

Protection of electrical installations and devices

A Type 2 surge protector is a key element in protecting electrical installations from the effects of current surges caused, for example, by lightning strikes. This device effectively protects connected receivers, minimizing the risk of damage and downtime. This model, with a capacity of 40 kA, is designed for use in single-phase (1P) installations with a voltage of 440V.

Construction and application

This surge protector, mounted on a TH-35 mm DIN rail, occupies only 1 module in the switchgear cabinet. Its construction based on T2 technology makes it ideal for protecting against overvoltages resulting from indirect lightning strikes or maneuvers in the power grid. The optical indication of the device's status informs about its operation, which facilitates diagnostics and a quick response in the event of a failure. The ability to connect wires with a cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible) ensures compatibility with most standard installations.

Key features and benefits

• Versatility: Provides protection in various network configurations – IT, TN-C and TN-C-S. This allows these surge protectors to be used in both home and industrial installations.
• High efficiency: Protection level of 2.1 kV guarantees effective protection against overvoltages.
• Compact dimensions: Occupies only 1 module in the switchgear cabinet, saving space.
• Optical indication: Allows quick identification of the device's status and the need for replacement after operation.
• Universal wires: Support for wires with a cross-section of up to 35 mm² ensures wide compatibility with different types of installations.
• Compliance with standards: Ensures safety and reliable operation in accordance with applicable standards.
• Designed for professionals: Facilitates installation and diagnostics thanks to a transparent design and optical signaling.
• Protection for the end user: Protects connected devices from damage caused by overvoltages, ensuring continuity of operation and minimizing repair costs.

This surge protector operates at a rated AC voltage of 230V and a maximum continuous AC operating voltage of 440V. The rated discharge current (8/20) is 20 kA, and the degree of protection is IP20. Mounting is on a TH-35 mm DIN rail, and the device is designed to operate with a single wire (without grounding). The protection level is 2.1 kV.

This surge protector is a reliable solution for anyone who cares about the safety of their electrical installation and protects their devices from the effects of sudden voltage surges. This is especially important in regions prone to frequent storms or in places with an unstable power grid.
