Surge protector iQuickPRD40r-T2-3 3-pole Type2 40 kA with contact A9L16293

Electrical installation protection with iQuickPRD40r-T2-3 surge limiters

The iQuickPRD40r-T2-3 surge limiter is a three-pole Class 2 device designed to protect electrical installations from the effects of atmospheric and switching surges. It provides effective protection in TN-C and IT networks, and its versatility makes it suitable for both residential and commercial buildings. Equipped with a remote signaling contact, it enables quick identification of any operation and taking appropriate action.

Construction and application

The device is mounted on a TH-35 mm DIN rail, which facilitates its installation in electrical switchboards. It is intended for protecting circuits with a rated voltage of 400V and a maximum continuous operating voltage of 350V. Its design allows for connecting wires with a cross-section of up to 35 mm², both solid and stranded, flexible. This limiter effectively protects against surges with a protection level of 2 kV (L-N and N-PE) and 2.5 kV (L-N). Optical signaling informs about the operation of the device, which is particularly important for quick failure diagnosis.

Key features and benefits

• High protection efficiency: Rated discharge current at 40 kA (8/20) guarantees effective protection against strong surges. Short-circuit withstand current (Isccr) is 20 kA.
• Versatility: Possibility of use in various network configurations (TN-C, IT) increases its scope of use.
• Status signaling: Built-in remote signaling contact and optical operation signaling facilitate monitoring the device status and quick reaction in case of failure.
• Safety: It has an integrated short-circuit protection, which further increases safety.
• Solid construction: Made of high-quality materials ensures durability and reliable operation for a long time. Protection degree IP20 provides basic protection against touch and dust.
• Compatibility: Adapted to cooperate with wires with a maximum cross-section of 35 mm², which allows its use in most standard electrical installations.
• Compliance with standards: The device meets safety standards, which confirms its quality and reliability.
