Promov SPD Backup Protector (SSD)-Ultimate External Disconnector for Surge Protection Devices
Product Features
● High-Energy Contact Design: Engineered for an extended service life and heavy-duty industrial applications.
● Excellent Surge Withstand Capability: Built-in anti-nuisance tripping technology ensures continuous protection during lightning events.
● Ultra-Low Tripping Current: Precision tripping at power frequency current ≤ 3±1A for rapid fault isolation.
● Superior Short-Circuit Breaking Capacity: Advanced integrated arc-extinguishing structure achieves a maximum 100kA breaking capacity.
● Universal Compatibility: Modular design with standard 35mm DIN rail mounting, fully compatible with Type 1 (T1), Type 2 (T2), and Type 3 (T3) SPDs.
Scope Of Application
Invented and manufactured by Xiamen TAIHANG Technology, and marketed globally under the Promov brand, the SSD (SPD Specific Protection Device) serves as a professional SPD backup protector and optimized SPD external disconnector. This pioneering technology fills a critical gap in low-voltage lightning protection systems worldwide.
Unlike ordinary fuses or standard circuit breakers that suffer from protection blind spots, the Promov SPD Backup Protector eliminates fire hazards triggered by SPD thermal degradation and grid faults. Simultaneously, it prevents premature SPD breakdown caused by the malfunction of traditional backup devices during lightning surges, maintaining long-term, reliable defense for all voltage-switching and voltage-limiting SPDs.
The entire product line complies with international and industrial standards, including GB18802.1, GB50057, and THQBOOI-2013, ensuring reliable global certification.
Core Patented Technologies
1.Dual-Channel Design: Effectively separates high-frequency lightning surges from low-frequency power frequency currents.
2.High-Energy Alloy Contacts: Delivers outstanding surge withstand capabilities up to 100kA (8/20$\mu$s) and 25kA (10/350$\mu$s).
3.Ultra-Low 3A Tripping Current: Provides ultra-fast response and strong anti-interference performance.
4.Low Impulse Residual Voltage: Maintains a residual voltage level equivalent to a common conductor, maximizing equipment safety.
5.High Breaking Capacity: Integrated arc-extinguishing structure handles up to 100kA short-circuit currents.
Target Markets & Applications
As a premier surge circuit breaker for Surge Protection Devices (SPDs), Promov has become the preferred choice in Southeast Asia’s thunder-prone markets, including Thailand, Malaysia, and Indonesia. It is widely deployed as a matched protection accessory for CCTV camera SPDs and power distribution systems in local smart city initiatives, infrastructure projects, and power grids.
