Surge protective device iPRD8-T23-3N 3+1 pole Type2+Type3 8 kA with contact A9L08601

Protection of electrical installations and devices – surge arrester iPRD8-T23-3N

This 3+1-pole type 2 and 3 surge arrester with a current of 8 kA is a key element in protecting the electrical installation from the effects of atmospheric overvoltages and network disturbances. The device effectively protects connected devices, minimizing the risk of damage and downtime. Equipped with a remote signaling contact, it enables quick identification of a surge and taking appropriate action.

Construction and application

The arrester is designed for mounting on a DIN TH-35 mm mounting rail. Its compact size – 4 modules – allows for easy integration with an existing switchgear cabinet. Optical indication of the device status facilitates diagnostics and maintenance. Designed for TN-S and TT network systems, it provides versatile applications in both domestic and industrial installations. Rated AC voltage at 400 V and a protection level of 1.4 kV guarantee effective protection against various types of overvoltages.

Key features and benefits

• Versatile protection: The combination of types 2 and 3 provides comprehensive protection against impulse overvoltages and residual transient voltages.
• Fast signaling: The built-in remote signaling contact allows for immediate notification of arrester operation, enabling a quick response and minimizing installation downtime.
• High durability: Maximum discharge current at 8 kA and short-circuit withstand (Isccr) of 50 kA ensure reliable operation in harsh conditions.
• Installation flexibility: Compact dimensions (4 modules) facilitate installation in tight switchgear cabinets.
• Compatibility with different networks: Support for TN-S and TT networks increases the range of applications.
• Safety of use: Compliance with safety standards confirmed by the CE marking.
• Large section wires: Possibility to connect wires with a cross-section of up to 25 mm² (solid/stranded) and 16 mm² (flexible).
• L-N and N-PE protection level: At 1.1 kV, it provides effective protection against overvoltages between individual conductors and between the neutral conductor and earth.
• Rated discharge current - peak value (8/20): At 2.5 kA, it provides effective protection against sudden voltage surges.
