Surge protective device iPRD40r-T2-3 3-pole Type2 40 kA with contact A9L40301

Electrical installation protection with surge limiters Acti9 iPRD

The iPRD40r-T2-3 surge limiter is a key element of every modern electrical installation, providing effective protection against the effects of lightning strikes and voltage surges in the network. This device, designed for mounting on a TH-35 mm DIN rail, protects against damage to electrical and electronic equipment, and also minimizes the risk of fire. The three-pole design (3P) and Type2 class make these limiters ideal for use in main and sub-distribution boards, providing comprehensive protection for the entire facility.

Functionality and application

The iPRD40r-T2-3 limiter is designed to protect against overvoltages in TN-C network systems. Its task is to discharge excess energy to the ground in the event of a sudden voltage increase, which prevents damage to connected devices. The built-in remote signaling contact informs about the operation of the limiter, enabling a quick response and problem location. Optical indication of the device status further facilitates diagnostics. The rated discharge current of 40 kA (8/20) guarantees high protection efficiency even with strong surge pulses.

Key features and benefits

• High protection efficiency: Rated discharge current of 40 kA provides protection against strong surges.
• Status indication: Built-in remote signaling contact and optical indication of operation facilitate diagnostics and quick response.
• Versatility: Designed for TN-C network systems, making it compatible with most electrical installations.
• Compact dimensions: Occupies only 3 modules on the DIN rail, allowing you to save space in the distribution board.
• Safety: Compliance with safety standards ensures reliable operation and minimizes the risk of failure.
• Durability: Short-circuit strength at 50 kA provides resistance to damage during short circuits in the installation.
• Flexibility: The possibility of connecting wires with a cross-section of up to 35 mm², both solid and stranded, ensures easy integration with various types of cabling.

The iPRD40r-T2-3 surge limiter is characterized by a discharge current of 40 kA and a rated AC voltage of 350 V. The L-PE/N-PE protection level is 1.4 kV, and the mounting is on a TH-35 mm DIN rail. The device is three-pole (3P) and designed to operate in TN-C network systems.

The iPRD40r-T2-3 surge limiter is an investment in the safety and reliability of the electrical installation, which translates into peace of mind for users and minimization of costs related to repairs and downtime caused by surges. It is a product recommended for both professional installers and demanding end customers looking for comprehensive protection of their electrical devices.
