The Acti 9 iQuick PRD40r surge arrester from Schneider Electric is a plug-in protection module for low-voltage distribution systems. It protects consumer installations and operating equipment against transient overvoltages caused by lightning strikes or network disturbances. The device is part of the IQuick PRD series and belongs to the Acti9 product range. It is classified as a Type 2 surge arrester, meaning it is intended for use in distribution switchgear, where it serves as the primary protection level. The technology is based on a combination of MOV (Metal Oxide Varistor) and GDT (Gas Discharge Tube), enabling efficient overvoltage diversion.

Applications

The arrester is designed for electrical distribution networks and is particularly suitable for installations in TN-S and TT earthing systems. It protects the electrical installation against short-term voltage surges caused by external influences such as thunderstorms or internal disturbances such as switching operations. The application is in distribution enclosures, where the device is mounted on a DIN rail. The operating altitude is up to 2,000 m above sea level, allowing use in various geographical regions. The operating ambient temperature ranges from -25 °C to 60 °C, and the storage temperature ranges from -40 °C to 70 °C. The relative humidity may range from 5 % to 95 %.

Functions and Equipment in Detail

The device features an integrated circuit breaker with a maximum short-circuit current (Icu) of 20 kA, which acts as a pre-fuse and disconnects the arrester in case of a fault. It is equipped with a remote signalling contact consisting of a normally closed contact (1 SD, 1 W). This contact enables monitoring of the arrester's status, for example, in an alarm or monitoring system. The signal circuit voltage is 2 A/250 V AC at 50/60 Hz. The terminals consist of tunnel terminals: top for cross-sections from 2.5 to 35 mm², bottom for 2.5 to 25 mm². The tightening torque is 2.5 Nm.

Technology Explained Simply

The arrester protects the electrical installation by diverting overvoltages above a defined protection level (Up). The protection level is 1.5 kV in common-mode operation (L/PE and N/PE) and 2.5 kV in differential-mode operation (L/N). The maximum continuous voltage (Uc) is 264 V for N/PE and 350 V for L/PE and L/N. The rated operating voltage (Ue) is 230/400 V AC (±10 %) at 50/60 Hz. The maximum surge current (Imax) is 40 kA in all operating modes, and the nominal surge current (In) is 20 kA. These values ensure high protection performance against transient disturbances. The protection class IK05 corresponds to IEC 62262 and protects the device against mechanical impacts such as shocks or vibrations.

Compatibility and Accessories

The device is designed for mounting on a DIN rail and conforms to the 9-mm pitch with a height of 14.7 units. It is compatible with replacement modules such as the A9L16310 (C40-350 for iQuick PRD40r). Other suitable models include the A9L16293 (3-pole 350 V with remote signalling contact), the A9L16292 (1-pole+N 264 V with remote signalling contact), and the A9L16297 (iQuick PRD20r 3p+N 264 V with remote signalling contact). These modules can be exchanged according to requirements to adapt the protection function.

Mounting and Installation

Mounting is done by plugging onto a DIN rail in the distribution enclosure. The dimensions are 131.5 mm (width), 94 mm (height), and 75.9 mm (depth). The product weight is 0.86 kg. The colour is white (RAL 9003). The terminals are designed for cross-sections from 2.5 to 35 mm² (top) and 2.5 to 25 mm² (bottom). Mounting is done with a tightening torque of 2.5 Nm. The protection class IK05 ensures mechanical robustness.

Advantages in Operation

The arrester provides reliable protection for distribution systems with high surge current capacity. The integrated pre-fuse protects the device itself and prevents damage in case of a fault. The remote signalling contact enables remote monitoring of the status, which is beneficial for maintenance and safety of installations. The plug-in design allows easy maintenance and replaceability of protection modules. Compliance with standards EN 61643-11:2012 and IEC 61643-11:2011, as well as certifications CE, KEMA-KEUR, and NF, guarantees conformity with European safety standards. The warranty period is 18 months.
