Surge arrester iPRD1 12.5R-T12-3 3-pole Type 1+2 (class B+C) A9L16382

Surge protector iPRD1 12.5R-T12-3 is a three-pole device from the Acti9 series, designed to protect electrical installations in residential and commercial buildings. It provides effective protection against the effects of surges, both direct (lightning strikes) and indirect (switching, disconnections). It is a type 1+2 surge protector, which means it combines the functions of protection against differential and common mode surges.

The device is characterized by high efficiency – a surge current of 12.5 kA (10/350 µs) guarantees protection even with strong impulses. Equipped with a signaling contact, it informs about the need to replace the cartridge after operation. This means that the user or installer is immediately informed of the loss of the device's protective ability. Additionally, optical status indication allows for a quick visual assessment of correct operation.

The construction based on spark gap-varistor technology (MOV + GDT) ensures reliability and long life. Mounting is done on a standard DIN TH-35 mm rail, which facilitates integration with the existing electrical installation. The maximum wire cross-section of 35 mm² (solid/stranded) and 25 mm² (flexible) ensures compatibility with various types of cabling.

The iPRD1 12.5R-T12-3 surge protector is dedicated to TN-C networks, which means it can be used in installations with a PEN protective earth and neutral conductor. The protection level of 1.5 kV provides effective protection against damage to sensitive electronic devices. The device meets the requirements of EN 61643-11:2012 and IEC 61643-11:2011 standards, which confirms its safety and compliance with applicable regulations.

• Versatile application: ideal for residential buildings and small commercial facilities requiring comprehensive surge protection.
• Status indication: signaling contact and optical indication facilitate monitoring of the device's status and quick reaction in the event of a failure.
• Easy installation: mounting on a standard DIN TH-35 mm rail simplifies installation and integration with existing electrical infrastructure.
• High efficiency: surge current of 12.5 kA provides effective protection against strong surges.
• Compliance with standards: meeting the standards EN 61643-11:2012 and IEC 61643-11:2011 guarantees safety and reliability.
• Network compatibility: designed to operate in TN-C networks, commonly used in residential and commercial buildings.

The iPRD1 surge protector is an investment in the safety of the electrical installation and protected devices – from protecting RTV/AGD equipment from damage to ensuring the continuous operation of building automation systems or emergency lighting.
