General Description: The SINOTIMER SMQ5-125 is a high-power automatic transfer switch designed for safely switching between two power sources, such as the main electrical grid and a generator or inverter. The switch ensures continuous power supply to consumers by automatically switching to the backup source in case of main source failure.

Components and Controls:

• Automatic / Manual Operation Selector
• Rotary lever for immediate mechanical switching
• LED indicators showing voltage presence on the normal source
• LED indicators showing voltage presence on the backup source
• Clear indicators for Normal Capacity (N) and Emergency Capacity (R)
• Direction indicators showing switching direction

Electrical Connections:

• Main power input: L phase, N neutral
• Backup power input: L phase, N neutral
• Output to load: L phase, N neutral

Important Notes:

• No short-circuit protection provided
• Does not replace switches or fuses
• Use with appropriate higher-level protections is recommended
• Does not allow simultaneous operation of both sources
