Description

The HCG4-4000 DC Switch-disconnector is designed for DC systems rated up to 1500V and 4000A. It provides reliable connection, breaking, and isolation functions, making it ideal for energy storage, photovoltaic (PV), and DC distribution applications.

Key Features:

• Ultra-Compact Design: Special two-pole DC structure with only 259 mm width – 40% smaller than traditional AC-to-DC products, significantly reducing cabinet size.
• Low Power Consumption: Long-term through-flow temperature rise less than 50K.
• High Reliability: Two-pole design reduces system stress by 50%. Maintenance-free mechanical life up to 10,000 cycles.
• UL Certified: Compliant with UL 489 B (E541391) and accessories (E541395).

Available Accessories:

Closing coil, shunt trip coil (including holding type), motor operating mechanism, undervoltage trip coil (with 0/1/3/5 s delay), auxiliary switch (4NO+4NC or 5NO+5NC), button blocking, door frame, opening position lock.

Wiring & Installation:

Horizontal wiring, supports upper or lower incoming line. Busbar connection uses M12 grade 8.8 bolts (60 N·m torque). Protection degree IP20. Operating temperature: -40°C to +70°C (no derating required). Altitude up to 5000 m (no derating).
