Surge protector operating voltage 460 V SPCT2-460/1 167608

Surge protection in the installation – reliability and safety

Surge protector SPCT2-460/1 is a key element in protecting the electrical installation from the effects of current surges and overvoltages that can damage sensitive electronic devices. The device is designed for mounting on a TH-35 mm DIN rail and provides effective protection in networks with a rated voltage of 460V. Its compact size – only 1 module – allows for easy integration with the existing switchgear.

Functionality and application

The SPCT2-460/1 surge protector is classified as a Type 2 device, which means it works perfectly as the second stage of protection in a surge protection system. It provides protection against indirect effects of lightning strikes and overvoltages generated by devices inside the building. It is compatible with TN and TN-S network systems, as well as other network systems, making it a universal solution for various installations. Optical indication of the operating status facilitates quick identification of the need for replacement.

Key features and benefits

• High protection efficiency: Rated discharge current up to 20 kA (8/20 µs) and maximum discharge current 40 kA guarantee effective protection against high overvoltages.
• Versatility: Compatibility with various network systems (TN, TN-S and others) allows the surge protector to be used in a wide range of installations.
• Compact dimensions: Occupies only 1 module on the DIN rail, making it easy to install even in crowded switchboards.
• Simple diagnostics: Optical indication of operation informs about the need to replace the insert, simplifying servicing.
• Safety: Overload protection up to 125A (series overcurrent protection) additionally protects the installation.
• Large conductor cross-section: The ability to connect conductors with a cross-section of up to 25 mm² (single-/multi-stranded) or 35 mm² (flexible) provides flexibility when selecting power cables.
• Protection level: Provides a protection level of 2.2 kV, which is sufficient for most domestic and industrial applications.

The maximum continuous operating AC voltage is 460 V, and the rated discharge current (8/20 µs) is 20 kA. The maximum discharge current (8/20 µs) reaches a value of 40 kA with a protection level of 2.2 kV. The device is classified as Type T2 and is mounted on a TH-35 mm DIN rail.

The SPCT2-460/1 surge protector is an investment in the safety and reliability of the electrical installation, which protects devices from costly failures caused by overvoltages. This is particularly important for sensitive electronic devices such as computers, televisions or home automation systems. Installing this surge protector is a simple procedure for every electrical installer, and the benefits will be felt by both him and the end user.
