Surge protector iQuickPRD40r-T2-1N 1+1-pole Type2 40 kA with contact A9L16292

Electrical installation protection with iQuickPRD40r-T2-1N surge limiters

The iQuickPRD40r-T2-1N surge limiter is a key element in protecting electrical installations from the effects of lightning strikes and surges. The device is designed for mounting on a TH-35 mm DIN rail and provides protection in TN-S and TT network systems. Its task is to minimize the risk of damage to electrical equipment, as well as to prevent fires caused by overloads.

Characteristics and application

This single-pole Type 2 limiter, with a maximum discharge current of 40 kA, effectively protects against the effects of surges that can result from lightning strikes or the switching of large loads. It has optical indication of operation, which makes it easier to identify situations requiring intervention. The integrated short-circuit protection further increases safety. The wire cross-section up to 35 mm² allows connection of both rigid and flexible wires.

Advantages and benefits

• High protection efficiency: Rated discharge current of 20 kA (peak value) and maximum discharge current of 40 kA guarantee effective protection against surges.
• Versatility: The possibility of use in TN-S and TT network systems makes the limiter compatible with different types of electrical installations.
• Optical signaling: The built-in optical indicator informs about the operation of the device, which facilitates diagnosis and quick response.
• Safety: Integrated short-circuit protection minimizes the risk of damage and ensures safe operation.
• Easy installation: Mounting on a standard TH-35 mm DIN rail is simple and quick, which translates into time savings during installation.
• Large wire cross-section: Support for wires up to 35 mm² provides flexibility in selecting appropriate cables.
• Protection level: Provides a protection level of 1.5 kV L-N and L-PE/N-PE, which is sufficient for most domestic and industrial applications.
• Short-circuit strength: It has a short-circuit strength (Isccr) of 20 kA, which increases its reliability in difficult working conditions.

This limiter is an ideal solution for both professional installers and end-users looking for reliable protection of their electrical equipment against the effects of surges. Its compact size (4 modules) allows for easy adaptation to an existing distribution board.
