This adaptability makes TiraThai's LV Switchgear a cornerstone for efficient, scalable low-voltage power distribution worldwide.

Key Features and Engineering Excellence

TiraThai's LV Switchgear is engineered for versatility and safety, incorporating advanced features to meet modern power demands. The modular cabinet options—GGD (fixed-type for distribution), GCS (withdrawable for flexibility), and MNS (compact, multi-functional)—support diverse applications, from power distribution to motor control centers (MCC). Each cabinet integrates circuit breakers (MCCB or ACB), busbars, and secondary terminals, with options for intelligent relays and SCADA integration for real-time monitoring and fault diagnostics.

The "five prevention" interlock system ensures safety by preventing misoperation, live part access, accidental breaker closure, incorrect grounding, and live interval entry. Enclosures, made from cold-rolled steel or aluminum-zinc alloy, offer IP40/IP54 protection against dust and water, with corrosion-resistant coatings for durability in harsh environments. The design supports high breaking capacities (up to 80kA) and short-circuit withstand (40kA/1s), ensuring robust fault protection.

Jinguan Electric's automated production—featuring precision assembly, vacuum testing, and AI-driven quality checks—guarantees defect-free units. Compared to traditional LV panels, TiraThai switchgear reduces footprint by 25%, cuts installation time, and achieves >99% power continuity. Optional features like reactive power compensation and harmonic filters enhance efficiency, while low noise (under 55dB) suits urban installations. These attributes exceed IEC 61439-1 and GB/T 7251.1 standards, delivering a switchgear solution that balances intelligence, safety, and scalability.
