ABB SPD 40K

The surge protection device (SPD) is engineered to meet IEC 61643-11 / EN 61643-11 standards, providing essential protection for low voltage distribution systems, including TN-S and IT configurations. It operates at a rated voltage of 400 V AC and can handle nominal AC voltages of up to 690 V. With a voltage protection level of 1.8 kV between line and neutral and 3.8 kV between neutral and earth, this device effectively shields electrical systems from damaging transient overvoltages, such as those caused by lightning.

Designed for ease of installation, the SPD features a DIN-Rail mounting type and has a compact size of 71.2 mm in width, 88 mm in height, and 58 mm in depth, weighing only 0.48 kg. It boasts a maximum continuous operating voltage of 440 V (L-PE) and a temporary overvoltage test value of 581 V. With a rated service short-circuit breaking capacity of 100 kA, it ensures reliable performance under fault conditions.

The device is classified as an arrester class II and supports a maximum discharge current of 20 kA (8/20 µs), with impulse current handling of 2 kA (10/350 µs). Its IP20 protection degree makes it suitable for indoor applications, and it is compliant with RoHS and relevant safety certifications, including CB and CQC.

Featuring a status indicator, the SPD provides visual confirmation of its operational status, making it a practical choice for both residential and commercial buildings. With robust specifications and ease of use, this SPD is a vital component for enhancing the safety and reliability of electrical installations.
