Automatic power switch 4P 200A HIC420G

4-Pole Automatic Transfer Switch – Reliable Switching in Critical Installations

The device ensures fast and safe power transfer between two energy sources (e.g., grid and generator) without interrupting connected loads. Thanks to the built-in motor drive and latching mechanism, the switch operates automatically in the event of a voltage loss, while also allowing manual operation and padlock locking – convenient both for the installer during configuration and for the end-user requiring certainty of the emergency system's operation.

Key Features and Benefits

• Rated continuous current 200 A at voltage 380‑415 V – ideal for large industrial circuits and public utility buildings.
• Short-circuit capacity 50 kA (with gl‑gG fuse) and short-time withstand current 12 kA – protects the installation against extreme overvoltages.
• Switching capacity 131 kW at 400 V (AC‑1) and operating capacity at AC‑23 of 90 kW – ensures stable operation under high starting loads.
• Built-in motor drive enables fast switching in automatic mode and precise setting of transfer and return times.
• Latching mechanism and padlock locking capability – increases safety of manual operation and prevents unauthorized switching.
• One NO auxiliary contact – allows connection of an additional signaling or control circuit without the need for extra modules.
• Fixed mounting construction (device permanently mounted) and compatibility with distribution boards – facilitates installation in standard electrical cabinets.
• IP00 protection class on the front and no requirements for front mounting – the device is intended for enclosed housings, reducing the risk of mechanical damage.

Installation and Compliance

The switch is designed for installation in distribution boards as a fixed component, eliminating the need for additional support structures. It complies with standards IEC EN 60947‑3 and European requirements for safety and electromagnetic compatibility. Thanks to the simple main terminal clamps, the installer can quickly connect cables with large cross-sections while maintaining high connection quality.

Thanks to this combination of technical parameters and practical conveniences, the HIC420G automatic transfer switch proves effective both in new industrial projects and in modernizing existing emergency power systems.
