GATS-S7 Automatic Transfer Switch

  • Dual Architecture Flexibility: Unique option to choose between CB Class (with overcurrent/short-circuit protection) and PC Class (high withstand current) to match specific project requirements.
  • Critical Safety Integration: Standard built-in Fire Linkage (DC24V forced splitting) and Generator Start Signal, eliminating the need for external controllers.
  • High Load Adaptability: Rated AC-33iB, ensuring safe switching for mixed loads including motors, elevators, and water pumps without contact fusion.
  • Patented Compact Design: National patented integrated mechanical interlock reduces cabinet space, optimizing panel layout and costs.
  • Wide Application Range: Covers 16A to 250A (3P/4P), ideal for hospitals, high-rise buildings, and industrial power systems requiring high reliability.

Description

Ensure continuous power supply for critical infrastructure with the GATS-S7 Dual Power Automatic Transfer Switch. Designed for high-stakes applications such as hospitals, shopping malls, high-rise buildings, and fire protection systems, this ATS switch offers a robust solution for transferring loads between a main power source and a backup generator or secondary utility line. With a rated voltage of 400V and coverage from 16A to 250A, it is the ultimate safeguard against power failure.

One Switch, Two Modes: CB Class & PC Class Optional

The GATS-S7 series breaks the mold by offering a unique “Dual Architecture” selection. Depending on your project’s single-line diagram requirements, you can select:

  • CB Class (Circuit Breaker Type): Provides built-in overcurrent and short-circuit protection, simplifying the distribution cabinet design by reducing the need for upstream protection components.
  • PC Class (Switch Disconnector Type): Focuses on high short-time withstand current capabilities to ensure power continuity without nuisance tripping during faults, ideal for fire fighting loads.

Built for Safety: Fire Linkage & Generator Control

Unlike standard transfer switches that require complex external wiring, the GATS-S7 comes standardized with critical safety features. It includes a built-in Fire Function interface (DC24V) to automatically cut off non-essential power during a fire emergency. Additionally, it features a dedicated Generator Start Signal output, which automatically wakes up your standby generator immediately upon detecting a mains failure.

Industrial-Grade Performance (AC-33iB)

Reliability is non-negotiable when switching inductive loads. The GATS-S7 meets the rigorous AC-33iB utilization category standards (IEC/GB). This means it is engineered to handle mixed load circuits including motors, elevators, fans, and water pumps. The robust contact system ensures that the switch can withstand the high surge currents typical of these devices without contact welding or failure.

Patented Compact Design

Featuring a national patented integrated design, the GATS-S7 utilizes a reliable mechanical interlock to physically prevent simultaneous connection of two power sources. Its compact footprint (e.g., the 63A frame is only 271mm wide) allows panel builders to optimize cabinet layout, saving valuable space and reducing enclosure costs.
