PRODUCT INTRODUCTION
DZ47HS series manual dual - power transfer switch(MTS) is mainly used in AC and DC circuits with a voltage range of 100 - 400V, serving as a dual - circuit transfer switch. When the main circuit is powered off or malfunctions, it can be manually switched to the standby circuit to ensure a stable power supply. It has a built - in interlocking structure, which prevents the two circuits from being powered on simultaneously. Additionally, it can provide overload and short - circuit protection functions, making it a switch device that integrates transfer and protection. It is often used in combination with equipment such as voltage regulators and EPS. This product complies with GB10963.2 and IEC60947-2 standards.

PRECAUTIONS AND WARNING
1, Ensure the switch is properly rated for the current, voltage, and frequency of the circuit it will control to prevent overloading and damage.
2, Always wear appropriate personal protective equipment (PPE) such as insulated gloves, safety glasses, and arc-flash clothing when operating or maintaining the circuit breaker.
3, Verify that the circuit is de-energized using a suitable voltage tester before performing any maintenance or inspection on the circuit breaker.
4, Avoid rapid or frequent switching of the circuit breaker, as this can cause excessive wear on internal components and reduce its lifespan.
5, Follow the manufacturer’s operating instructions and lockout/tagout procedures when isolating the circuit breaker to prevent accidental energization and ensure personal safety.
