Review SIEMENS Surge Bolt Shield Protector Breaker

The Siemens QSPD4A335 Surge Arrester Shield Protector Breaker is a vital component of electrical systems designed to protect against surges and overcurrents. This compact and robust device is engineered to provide superior levels of electrical protection for your electrical installations.

The key feature of this surge arrester shield protector breaker is its surge arrester function, which is specifically designed to safeguard your electrical system from damage caused by voltage surges. These surges can be caused by various factors such as lightning strikes, power line faults, or even switching operations. By intercepting these surges, the QSPD4A335 prevents the destructive energy from reaching the connected equipment, thus extending their lifespan and ensuring reliable performance.

The shield protector function of this device is another crucial aspect, which offers additional protection against electromagnetic interference (EMI) and radio-frequency interference (RFI). This feature is particularly important in applications where sensitive electronic equipment is installed, as it helps to maintain the electrical purity of the system.

The QSPD4A335 is a Type 2 surge arrester, which means it offers both differential and common-mode protection. This comprehensive protection makes it an excellent choice for a wide range of applications, including industrial control systems, power distribution systems, and telecommunications networks.

This surge arrester shield protector breaker is designed for use with low-voltage power distribution systems, with a nominal voltage rating of 400 V and a maximum current rating of 32 A. The device is compact and lightweight, making it easy to install in various locations. Its rugged construction ensures durability and reliability, even in harsh environments.

The QSPD4A335 is also equipped with a tripping characteristic that is designed to disconnect the power supply in the event of a fault or overcurrent condition. This feature is essential for maintaining safety and preventing damage to connected equipment.

In summary, the Siemens QSPD4A335 Surge Arrester Shield Protector Breaker is a versatile and effective solution for protecting electrical installations from damaging surges and overcurrents. Its surge arrester and shield protector functions offer comprehensive protection against electrical hazards, while its compact size and rugged construction make it suitable for a wide range of applications.

The Siemens QSPD4A335 surge protective device ( SPD ) is a type of electrical equipment designed to protect electrical installations from voltage surges and lightning strikes. Here are some pros and cons of buying this specific model:
