The HH15 (QSA) series 380V 3P 630A isolation switch fuse group represents a critical evolution in industrial electrical safety. As high-capacity power distribution becomes more complex, the need for components that combine load-breaking, isolation, and short-circuit protection is paramount. Our HH15 group is designed for AC 50Hz, rated voltage up to 380V, and current capacity reaching 630A, making it the backbone of motor protection and main circuit control.
In the context of Semantic Search and Information Gain, it is vital to understand that the HH15 is not just a mechanical switch; it is a thermal-magnetic management system. By integrating the fuse directly into the isolation mechanism, we significantly reduce "Contact Resistance" and minimize heat dissipation, which are the primary causes of switchgear failure in 630A high-load environments.
Our OEM HH15 uses optimized arc-extinguishing chambers, allowing for safe disconnection even under peak load conditions (up to 630A).
Features a visible break point and simultaneous 3-pole disconnection to ensure maintenance personnel safety during inspection.
Engineered for Industry 4.0 cabinets, the compact footprint allows for 20% more space efficiency compared to traditional switches.
Leading the transition from mechanical reliability to digital intelligence.
High conductivity copper contacts, silver-alloy plating, and robust spring-loaded mechanisms for 630A stability.
Deployment of built-in temperature and current sensors to provide real-time data to edge computing systems.
AI-driven analysis of contact wear and fuse health to predict failures before they impact industrial uptime.

For global enterprises, procurement isn't just about price; it’s about compliance and reliability (E-E-A-T). Our HH15 630A Isolation switches meet international standards such as IEC 60947-3. We offer extensive localization support, including technical documentation in multiple languages, customized OEM branding, and regional certification assistance (CE, CB, ROHS).
Our supply chain resilience is built on Yueqing’s massive industrial cluster, allowing us to maintain stable lead times even during global logistics disruptions. We understand the "Search Intent" of procurement managers—they need a partner, not just a vendor.
The HH15 isolation switch fuse group provides "Physical Isolation." While an MCCB provides protection, the HH15 ensures a visible air gap and physical disconnection, which is a mandatory safety requirement for maintenance in high-current industrial circuits.
Yes, it is designed specifically for 380V/415V systems with a high insulation voltage (Ui) rating of 800V, providing a significant safety margin against voltage spikes and transients.
We use silver-cadmium oxide or silver-tin oxide contact tips, which are cold-welded to the copper base. Each batch undergoes a temperature rise test at 110% of the rated current (693A) to ensure thermal stability.
Yes, while the standard is 3-pole (3P), we can provide a 4P version or a detachable neutral link depending on the local wiring regulations of the destination country.
