Solutions by application
Different environments place different demands on protection and control. Here is how LOGO products can support safer, more dependable operation when correctly selected and installed.
LOGO VA protectors monitor incoming voltage and current, disconnecting connected circuits during overvoltage, undervoltage or overcurrent conditions. Automatic reconnection helps restore operation after suitable supply conditions return.
LOGO VA protection helps reduce exposure to overvoltage, undervoltage and overcurrent conditions that can interrupt lighting, point-of-sale systems and other essential business equipment.
ATS and VA-ATS products coordinate transfers between grid and inverter supplies. VA-ATS models add voltage monitoring to help evaluate supply conditions as part of the transfer process.
Automatic and manual transfer switches provide controlled selection between grid and generator supplies. Clear source indication helps operators understand which supply is connected to the load.
Commercial installations can combine voltage monitoring, overcurrent protection and controlled source transfer to support continuity while helping isolate equipment from unsuitable supply conditions.
Compact DIN-rail devices bring monitoring, protection and source control into a central panel. Correct selection and professional installation help maintain clear, dependable distribution control.
Understand the risk
Voltage changes, unstable sources and poor connections can interrupt operation or damage equipment. The right protection strategy considers the entire installation.
Correct product selection is only one part of electrical safety. Cable sizing, terminal tightness, breaker coordination and professional installation remain essential.
