Varistor surge protector SIMTEC (B+C) ST30B+C1P 85202010

Protection of electrical installations against overvoltage

This SIMTEC ST30B+C1P varistor surge protector is a key element of the overvoltage protection system in electrical installations. Its task is to minimize the risk of damage to equipment caused by sudden voltage increases, such as those caused by lightning strikes or electromagnetic induction. This surge protector effectively protects against the effects of overvoltages in both TN and TT networks.

Construction and application

Type 1+2 surge protector (class B+C) is designed for mounting on a 35 mm rail according to EN 60715 standard. Its modular construction facilitates installation and replacement in case of failure. Thanks to the fast response time (≤ 25 ns) and high energy discharge capacity (30kA), it provides effective protection of sensitive electronic devices, such as computer equipment, alarm systems or RTV/AGD devices. This is particularly important in residential, office and industrial buildings.

Key features and benefits

• Versatile protection: Protects against atmospheric, induced and switching overvoltages.
• Fast response: Response time of less than 25 nanoseconds minimizes the exposure time of devices to the harmful effects of overvoltages.
• High energy discharge capacity: Rated current of 30kA guarantees effective protection even with strong overvoltages.
• Easy installation: Modular design and the possibility of mounting on a standard 35 mm DIN rail facilitate installation.
• Optical indication: Built-in optical indicator informs about the operation of the surge protector, which facilitates diagnostics and maintenance of the installation.
• Compliance with standards: Meets the requirements of IEC 61643-11 standard, which confirms its safety and effectiveness.
• Wire cross-sections: The possibility of connecting wires with a cross-section from 2.5 mm² to 35 mm², both solid and stranded, ensures compatibility with various types of installations.

The SIMTEC ST30B+C1P surge protector is a reliable solution for anyone who cares about the safety of their electrical installation and protects valuable equipment from damage caused by overvoltages. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.
