Eaton SPET2-280/1 C Surge Protection Device, 1-Pole, 20kA

The Eaton SPET2-280/1 C is a professional-grade 1-pole surge protection device engineered to protect electrical installations from transient voltage spikes. Designed for reliability, this Type 2 surge arrester effectively diverts excess energy to ground, preventing damage to sensitive electronic components and appliances within residential or commercial power distribution systems.

Advantages

This surge protection device offers a robust discharge capacity of 20kA, ensuring effective mitigation of overvoltages caused by switching operations or indirect lightning strikes. Its compact design allows for seamless integration into standard electrical cabinets, while the DIN rail mounting system facilitates quick and efficient installation. The device is built to high safety standards, providing long-term operational stability and peace of mind for your electrical infrastructure.

Suitable for

• Residential electrical distribution boards
• Commercial office power systems
• Protection of household appliances and sensitive electronics
• Integration into standard DIN rail mounting enclosures

When it may not be suitable

This device is a Type 2 surge arrester and is not intended to serve as a primary lightning protection system for direct strikes. It should not be used in environments where the expected surge current exceeds its rated discharge capacity or in systems requiring Type 1 or Type 3 protection without appropriate coordination.

Key specifications

• Number of poles: 1
• Type: 2
• Nominal discharge current: 20kA
• Mounting type: DIN rail
• Application: Power distribution systems

How to use

The Eaton SPET2-280/1 C must be installed by a qualified electrician in accordance with local electrical regulations. The device is snapped onto a standard 35mm DIN rail within the distribution board. Ensure that the phase and ground connections are securely tightened to the terminals to prevent overheating. It is recommended to install the device as close as possible to the incoming power supply to maximize its protective effectiveness.

What to consider before purchase

• Verify that your electrical system voltage is compatible with the device ratings.
• Ensure there is sufficient space on the DIN rail within your distribution board.
• Confirm that the device is part of a coordinated surge protection strategy if required by local standards.

Usage recommendations

Regularly inspect the status indicator of the surge protection device to ensure it remains operational. If the indicator shows that the device has reached the end of its service life, it must be replaced immediately to maintain system protection.
