Surge protective device iPRD20-T2-1N 1+1 pole Type2 20 kA A9L20500

Electrical installation protection with iPRD20-T2-1N

The iPRD20-T2-1N surge protector is a key element in protecting electrical installations from the effects of current surges, e.g. caused by lightning strikes. A Class Type 2 device, designed to work with overcurrent circuit breakers, effectively protects electrical and electronic devices from damage. Mounting on a TH-35 mm DIN rail ensures easy installation and integration with the existing system.

Construction and application

This surge protector is designed to protect circuits in TN-S and TT installations. Its 1+1 pole construction allows protection of both the phase and neutral conductor. A protection level of 1.1 kV (L-N) and 1.4 kV (N-PE) guarantees effective protection against overvoltages. Optical indication of operation facilitates quick identification of an emergency situation and location of the damage. Short-circuit strength at 50 kA demonstrates the robustness of the device and its ability to withstand extreme operating conditions.

Key features and benefits

• Effective protection: Rated discharge current of 20 kA provides high resistance to overvoltages, minimizing the risk of equipment damage.
• Versatility: Compatible with different network types (TN-S, TT), making it an ideal solution for both home and industrial installations.
• Easy installation: Mounting on a standard TH-35 mm DIN rail simplifies the installation process and integration with existing electrical infrastructure.
• Status indicator: Optical indication of operation allows for quick diagnosis of surge problems and effective response.
• Safety: Short-circuit protection (no integrated short-circuit protection requires the use of appropriate overcurrent protection – maximum 40A parallel fuse or 80A series fuse).
• Compact dimensions: Occupies only 2 modules in the distribution board, saving space.
• Large conductor cross-section: Supports conductors with a cross-section of up to 35 mm² (single-/multi-strand and flexible) providing flexibility in selecting conductors tailored to specific installation needs.
