Manual Transfer Switch
A clear visual break point allows you to confirm the circuit is fully isolated, ensuring absolute safety for all maintenance work.
Carefully selected materials and manufacturing processes ensure the product works steadily even in harsh environments.
Intuitive manual operation means you can quickly and accurately switch it without complex training.
Designed for versatile installation, perfectly suited for indoor distribution cabinets and outdoor substations.
An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source.
There are two types of automatic transfer switches, circuit breaker and contactor. The circuit breaker type has two interlocked circuit breakers, so only one breaker can be closed any anytime. The contactor type is simpler design that is electrically operated and mechanically held.
Transfer switches prevent the utility power and the generator from powering your household circuits at the same time. The result is called back feeding. When this happens, the results can be very dangerous and can include fires, serious injury, or even death.
Modern automatic transfer switches (ATSs) contain sensitive components that are highly susceptible to damage caused by transient voltage. Voltage monitoring control boards and control power supplies commonly fail due to damage caused by transient voltage. These failure modes result in ATS inoperability.
A transfer switch is required by the NEC for any connection of power to a home. Truly, using an ATS is the only safe way to directly connect a generator to your home. An automatic transfer switch isolates your home from the power lines.
