The remote signaling terminals on a Type 2+3 surge protective device (SPD) are used to connect alarms, or monitoring systems. Users can wire these to indicators, or buzzers, either for simple fault alarms or fail-safe monitoring.
Common applications of Type 2+3 Surge Protection Devices include residential buildings, commercial properties, and industrial facilities.
A Type 2+3 SPD (Surge Protection Device) is a combined device that provides multi-level protection against transient overvoltages caused by lightning strikes and switching events. It integrates the functions of Type 2 SPDs (protection at the sub-distribution board) and Type 3 SPDs (fine protection of sensitive end devices), ensuring a low protection level (Up) for your electrical system. This device is suitable for TT, TN-S, and TN-C-S (PME) systems, providing reliable surge protection for residential, commercial, and industrial installations.
Our Type 2+3 surge protection devices (SPDs) offer comprehensive protection and advanced design features:
A Type 2+3 SPD (Surge Protection Device) simplifies installation by combining the functions of separate Type 2 SPDs and Type 3 SPDs into a single device. Its compact, space-saving design ensures easy DIN-rail mounted installation, while providing comprehensive, coordinated protection for both main power lines and sensitive end devices. This integrated approach reduces installation complexity and guarantees low protection level (Up) for the entire system.
Type 2+3 SPDs are designed for easy DIN-rail mounted installation. They should be installed as close as possible to sensitive equipment, such as in sub-distribution boards, machine control cabinets, or directly upstream of end devices. For outdoor applications, these devices can be installed in waterproof enclosures, ensuring reliable surge protection under all conditions.
Yes, many Type 2+3 SPDs feature pluggable or modular designs, allowing quick replacement, flexible deployment, and easy maintenance, while maintaining reliable surge protection.
