Surge protector operating voltage 460 V SPCT2-460/4 167611

Protection of electrical installations against overvoltage

The SPCT2-460/4 surge protector from Eaton is a reliable device designed to protect electrical installations from the effects of overvoltage, both those caused by lightning strikes and disturbances in the network. Mounted on a DIN rail TH-35 mm, it is a key element of the protection system, especially in sub-switchboards. The device is type 2, which means it perfectly complements the operation of type 1 surge protectors, providing comprehensive protection.

Construction and application

The construction of the surge protector is based on varistor technology, which is characterized by a fast response time and a high ability to absorb energy. Thanks to this, SPCT2-460/4 effectively reduces the voltage to a safe level in the event of an overvoltage. Designed to operate in TN, TN-S and TN-C-S systems (as well as IT and others), it offers a wide range of applications – from home installations to industrial facilities. The four-pole construction (4P) ensures protection of all phase conductors. An optical indicator informs about the need to replace the insert after the surge protector has operated – red indicates damage, and green – correct operation.

Key features and benefits

• High efficiency: Rated discharge current at 20 kA (peak current of 8/20 µs) and maximum discharge current of 40 kA guarantee effective protection against even strong overvoltages.
• Versatility: Possibility of use in various network systems (TN, TN-S, TN-C-S, IT) increases the range of applications of the device.
• Easy diagnostics: Optical status indicator facilitates quick assessment of the surge protector's efficiency and allows for timely replacement of the insert.
• Safety: Protection against overload and short circuit (125.A fuse required) protects both the installation and the surge protector itself.
• Compatibility: Possibility of mounting on a standard DIN rail TH-35 mm facilitates integration with existing distribution boards.
• Capacity: Supports wires with a cross-section of up to 25 mm² (single-/multi-core) and 35 mm² (flexible) provides flexibility in the selection of power cables.
• Protection level: Provides a protection level of 2.2 kV, which translates into a high degree of safety for protected devices.

The SPCT2-460/4 surge protector is an investment in the safety and reliability of the electrical installation, which minimizes the risk of equipment damage and provides user confidence.
