Photovoltaic automatic reclosing switch: XY47-63 automatic reclosing miniature circuit breaker, suitable for lines with rated working voltage of 50Hz to 400V and rated working current of 80A. It can be used for remote automatic shutdown, opening and closing control, or automatic signal control.
At the same time, it also plays the role of overload and short-circuit protection for the circuit. It can also be combined with the under-voltage trip device to achieve the function of power-off activation and automatic power-off upon power restoration. Currently, it is widely used in photovoltaic grid-connected AC distribution boxes, as well as in situations where personnel cannot easily access, situations where maintenance personnel cannot arrive in time, unmanned值守 situations， and situations with high requirements for power continuity.
2. Self-recovery Overvoltage Protector: The self-recovery overvoltage protector is suitable for single-phase AC voltages of 220V, frequencies of 50Hz, and rated working currents of 60A or less for users or loads. It protects single-phase electrical equipment from single-phase line under-voltage caused by neutral line faults. It is mainly used to protect the incoming lines of residential household boxes or distribution lines that need to protect single-phase electrical equipment.
Instruction for Use:
When overvoltage or undervoltage occurs in a single-phase circuit, the circuit will automatically cut off, and the voltage of the single-phase circuit will return to normal. After a delay of 1-2 minutes, the circuit will automatically reset and reconnect, without the need for manual shutdown operation.
2. When transient or transient overvoltage conditions occur on the line, measured in seconds, the protector will not activate.
3. When the circuit experiences voltage instability due to faults such as accidental contact, or when there is a sudden power outage or power restoration, the protector will not connect the circuit.
4. When the line fault voltage reaches its maximum level, the protector itself will not be damaged.
5. The protector features inverse-time operation, and the action time is ≤ 1 second.
6. Voltage protection range: Below 40A, 0 – 450V; For 50/60A, 0 – 600V.
7. Impact tolerance voltage: 4kV (compliant with Class III electrical safety standards).
On the protection panel, there are dual-color indicator lights indicating the working status. The green light indicates normal line voltage, while the red light indicates either the positive or negative voltage of the line or a delay.
9. Modular design for the exterior, with rail installation.
10. Connection wire specification: Insulated wires with a cross-sectional area of 25mm2 or less.
11. Panel width: The first generation is 45mm, the second generation is 45mm x 36mm = 2pdz 47 (facilitating installation and use with size-restricted distribution boxes)
