Surge protector SPCT2-280/2 167594

Surge protection device SPCT2-280/2

The SPCT2-280/2 surge protection device from Eaton is a reliable device that effectively protects electrical installations from the effects of surges, both those caused by lightning strikes and disturbances in the network. It is a key element of protection for homes, commercial and industrial buildings, ensuring the safety of equipment and continuity of power supply. Mounting the surge protector in a sub-distribution board, behind the main type 1 surge protectors, provides an additional layer of protection.

Features and application

The device is designed for mounting on a TH-35 mm DIN rail and is characterized by a compact design – it occupies only 2 modules. The SPCT2-280/2 surge protector is type 2 (class C), which means it provides protection against switching surges and indirect lightning strikes. Optical signaling informs about any damage to the varistor insert, making quick response and replacement easier. This avoids downtime in the operation of the installation.

This surge protector finds wide application in:

• electric vehicle charging stations,
• battery energy storage systems,
• photovoltaic inverters on the AC side,
• heat pumps,
• three-phase receivers requiring strong but sensitive protection.

Parameters and benefits

This model of surge protector is characterized by a rated peak discharge current of 20 kA and a maximum discharge current of 40 kA. Its highest AC operating voltage is 280 V, and the protection level is 1.4 kV. The possibility of connecting wires with a cross-section of up to 25 mm² (single-/multi-strand) or 35 mm² (flexible) ensures compatibility with various types of installations. The device is designed to operate in TN and TN-S networks and other network systems. The lack of leakage current further increases safety.

It is worth paying attention to a few key advantages:

• Effective protection: Protects the circuit from overload and short circuit — like most circuit breakers in this class.
• Replaceable inserts: Allow for a quick response in the event of varistor damage and minimize installation downtime.
• Optical signaling: Allows easy assessment of the device's technical condition without the need for disassembly.
• Easy installation: Quick mounting on a TH-35 mm DIN rail facilitates installation and servicing.
• Versatility: Compatibility with different types of wires and network systems increases the range of applications.

The rated discharge current (8/20) is 20 kA, and the maximum discharge current (8/20) reaches 40 kA. The highest AC operating voltage is 280 V, and the protection level is 1.4 kV. The surge protector type is T2 (class C), and the mounting method is TH-35 mm DIN rail.
