The Havells 30A/2.5A SPN ACCL Automatic Source Changeover Switch offers reliable automatic power transfer between the mains supply and a standby generator for uninterrupted operation during power failures. Featuring an advanced microcontroller-based design, the ACCL continuously monitors the utility supply and automatically transfers the load to the generator whenever a power outage occurs. Once the mains supply is restored, the device safely reconnects the load after a preset delay.
Designed for 30A mains capacity (6000W) and 2.5A generator capacity (500W), the built-in Current Limiter (ACCL) prevents generator overload by disconnecting excessive loads, ensuring safe and efficient operation. This version is supplied without Generator Start/Stop (W/O GSS), making it suitable for manually started generators while still providing fully automatic load transfer.
Its compact DIN rail mounting, LED status indications, and compliance with IEC 60947-6-1 make it an excellent choice for residential homes, apartments, offices, and other single-phase backup power applications.
