WATSNB-32-3 PC Class R-iINT Automatic Transfer Switch by Schneider Wingoal

The WATSNB-32-3 PC Class R-iINT is an automatic transfer switch (ATS) under the Schneider Wingoal brand, with the following detailed specifications:

전기 수업: It belongs to the PC class, adopting an integrated load isolation switch as the executive component. It has no overcurrent protection function and requires an external circuit breaker, but it features stronger short-circuit withstand capacity and mechanical service life, with a mechanical lifespan of more than 5,000 운영.

정격 매개변수: Suitable for AC 50Hz, 380V systems, with a rated current of 32A and a 3-pole (3피) design, capable of supporting automatic switching between the main and backup power supplies.

Switching Modes: Equipped with switching modes including auto-transfer auto-reclose and auto-transfer non-reclose. Auto-transfer auto-reclose is the default mode, which automatically switches back to the normal power supply when the main power is restored; auto-transfer non-reclose remains on the backup power supply even after the main power is recovered after a fault transfer, suitable for generator backup power scenarios.

Switching Speed: The total transfer time is ≤ 50ms (1/4 cycle), which can ensure uninterrupted power supply for sensitive equipment such as medical instruments and servers.

Monitoring and Protection Functions: It can monitor the voltage and frequency of the dual power supplies in real time. When parameter anomalies occur (예를 들어, 저전압, overvoltage, 위상 손실), it will trigger switching. 그 동안에, it has a built-in forced neutral position function, allowing manual disconnection of dual power supplies in emergencies to meet fire linkage requirements.

통신 기능: Adopts a modular controller, available in basic and intelligent types, supporting RS485 communication (ModBus protocol) for easy integration into building management systems (BMS).

구조 설계: Utilizes double-row composite contacts, horizontal pull mechanism, micro-motor pre-energy storage and microelectronic control technology, achieving basically zero arc flash. It has obvious on-off position indication and padlocking functions, reliably realizing isolation between power supplies and loads.

Safety Certification: Complies with the IEC 60947-6-1 기준, and through strict electrical and mechanical interlocking design, it eliminates the risk of simultaneous connection of two power supplies.
