Surge protector SPCT2-280/1 167593

Electrical installation protection – reliable surge protector

The SPCT2-280/1 surge protector from Eaton is a key element in protecting electrical installations from the effects of surges, both those caused by lightning strikes and disturbances in the power grid. The device effectively reduces the voltage to a safe level, protecting connected devices from damage. This is particularly important for sensitive electronic equipment, such as electric vehicle charging stations, photovoltaic inverters, and heat pumps – areas where this model finds particular application.

The surge protector is designed for mounting on a TH-35 mm DIN rail and occupies only 1 module, making it easy to integrate with existing infrastructure. Optical signaling informs about any damage to the insert, enabling a quick response and replacement. The device's design provides protection in TN and TN-S network systems, as well as in other configurations. The maximum conductor cross-section of 25 mm² (solid/stranded) and 35 mm² (flexible) ensures compatibility with various types of cabling.

Key features and benefits

• Effective protection: Protects against the effects of direct and indirect lightning strikes and switching surges.
• Fast signaling: Optical status indicator informs about the need to replace the insert – green indicates correct operation, red – damage.
• Easy installation: Compact size (1 module) and mounting on a standard TH-35 mm DIN rail facilitate installation.
• Versatility: Designed for TN and TN-S systems and other configurations.
• High efficiency: Rated discharge current of 20 kA (8/20) and maximum discharge current of 40 kA provide effective protection even with large surges.
• Safety: Compliance with IEC 61643‑1+A1 standard for class I+II protection guarantees a high level of safety.
• Practical solution for installers: Simple installation and intuitive signaling facilitate work during installation and maintenance.

Technical parameters and application

The SPCT2-280/1 surge protector is a type 2 device, which means it complements the protection provided by type 1 surge protectors (installed at the LPZ 0/1 boundary). Its protection level is 1.4 kV, and the rated AC voltage is 280 V. The device does not have a remote signaling contact or an integrated overcurrent protection, but can be used with a fuse with a maximum value of 125 A for additional protection of the installation. Thanks to this, it is a reliable solution for protecting various electrical receivers in residential, commercial and industrial buildings.
