Specifications
Product Description
The 2P ATS 100A Tongou TOWTS-100 Transfer Switch is an automatic dual power switch designed to ensure continuous supply in single-phase 230 V installations. When the main grid fails, it autonomously switches to the backup source (generator, inverter/auxiliary grid), and returns to normal when service is restored. With a 100 A capacity, AC-33B utilization category, and transfer time under 50 ms, this ATS is optimized for PZ30 panels, modular panels, and critical residential or commercial applications.
Main Features
- Automatic and manual switching with front selector (Auto/Manual) and mechanical control.
- Rated current 100 A (series with ranges 16…100 A) and use in 230 V AC single-phase.
- Transfer time < 50 ms (operation and return), off-time ≤ 50 ms.
- AC-33B category for inductive loads and motors; suitable for demanding use.
- Control circuit at 50 Hz, control voltage AC 220–230 V (110 V option).
- Conditional short-circuit capacity 50 kA with SCPD type RT16-00-63A.
Advantages or Benefits
- Service continuity: fast switching to protect sensitive equipment and avoid downtime.
- Easy installation: compact format for PZ30 boxes/DIN rail and accessible terminals.
- Operational flexibility: automatic mode for daily operation and manual for maintenance or testing.
- Increased safety: A/B source indication, interlocks, and compatibility with upstream protection.
- Long service life: 2000 electrical operations and 5000 mechanical under normal conditions.
Purpose or Applications
Ideal for switching between grid and generator, between grid and inverter/UPS, or between two supply lines in homes, small businesses, technical rooms, telecom, pumping, and self-consumption AC systems where a 2P 100A automatic transfer switch is required.
