Eaton SPCT2-460/4 Surge Protection Device, 4-Pole, 40kA, 460V

The Eaton SPCT2-460/4 is a high-performance 4-pole surge protection device engineered to provide robust defense against transient overvoltages in electrical systems. Designed for reliability and safety, this Type 2 SPD effectively diverts excess energy caused by switching operations or indirect lightning strikes, thereby protecting sensitive electronic equipment and connected infrastructure from potential damage. Its compact design and standardized mounting make it an essential component for maintaining the integrity of power distribution networks.

Advantages

This surge protection device offers a high discharge capacity of 40kA, ensuring it can handle significant energy surges without compromising its protective function. The 4-pole configuration provides comprehensive coverage for three-phase systems with a neutral conductor, offering balanced protection across all phases. Its durable construction is built to withstand demanding industrial and residential environments, providing long-term operational stability and reducing the risk of costly equipment downtime due to electrical disturbances.

Suitable for

• Industrial power distribution boards
• Residential electrical installations
• Protection of sensitive electronic control systems
• Three-phase power networks with neutral

When it may not be suitable

This device is classified as a Type 2 surge protector and is not intended to serve as a primary lightning arrester for direct lightning strikes. It should not be used in environments where the expected surge energy exceeds its rated discharge capacity or in systems with voltages outside its specified operating range.

Key specifications

• Number of poles: 4
• Maximum discharge capacity: 40kA
• Rated voltage: 460V
• Device type: Type 2

How to use

The Eaton SPCT2-460/4 is designed for installation within a standard electrical distribution panel on a DIN rail. It should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is connected in parallel with the power supply, ensuring that the surge current is safely diverted to the ground. Proper wiring and secure terminal connections are essential for the device to function correctly and provide the intended level of protection.

What to consider before purchase

• Verify that the system voltage matches the 460V rating
• Ensure the distribution board has sufficient space for a 4-pole module
• Confirm that the device is compatible with your specific earthing system

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