YES1-63MA PC-CLASS AUTOMATIC TRANSFER SWITCHING EQUIPMENT

"Household Automatic Transfer Switching Equipment - Our company's latest R&D product, a micro residential power transfer switch. This is a PC class infrequent transfer switch with two position structure. Suitable for AC 50/60Hz, rated current 6A to 63A AC distribution systems. Mainly used to detect normal status of user's power supply. When one power source becomes abnormal, immediately switches to the other. Features both mechanical and electrical interlocking to prevent simultaneous closing of both power sources. Ensures continuity, reliability, and safety of power supply.

It is suitable for distribution systems with a rated operating voltage of AC 400 V. When the power supply experiences phase loss, overvoltage, undervoltage, or other faults, the transfer switch, under controller supervision, can swiftly transfer the load from the primary power source to the backup power source—provided that the backup source is functioning normally. Users may also, as needed, place the load in an intermediate position, disconnecting it from both the primary and backup power sources. This product is primarily intended for Class I and Class II loads as defined by national standards and is widely applicable to facilities requiring uninterrupted power supply, such as fire‑fighting systems, postal and telecommunications facilities, hospitals, hotels, urban rail transit systems, high‑rise buildings, industrial production lines, and television stations.

YES1-1600S PC

This series of control and protection switchgear represents a new generation of low-voltage electrical apparatus, offering a range of advantages, including integrated control and protection functions, modular construction, compact dimensions, a high degree of protection against environmental contamination, and convenient installation, operation, and maintenance. It is primarily intended for use in AC power systems with a frequency of 50 Hz, a rated insulation voltage of up to 690 V, and currents ranging from 0.2 A to 125 A, where it can make, carry, and break current under normal conditions—including specified overload conditions—and can also make, carry, and break current under specified abnormal conditions (such as short-circuit currents).
