First, the scope of application
RMGQY self-resetting over-voltage over-voltage delay protection device is also known as automatic reset over-voltage undervoltage protection (hereinafter referred to as self-reset over-voltage protection device), for single-phase AC voltage 220V, frequency 50Hz, rated working current 60A And the following user or load. As a result of the neutral line fault caused by the single-phase line undervoltage on the protection of single-phase electrical equipment. Mainly used for residential household box into the line or need to protect the single-phase power equipment, the protection of distribution lines.
Our production of automatic reset overvoltage undervoltage protector compared to the early product 45mm wide in size a lot smaller, our product width compressed to 36 mm, control the current, quite easy to install the control box, control Circuit board selection of imported components assembly, the product with the standard production standards, excellent performance and reliable. Can work properly in the case of abnormal voltage. When the mains voltage exceeds the preset voltage of the protector or below the undervoltage operating voltage of the protector, the protector can quickly and reliably cut off the circuit to protect the electrical safety. When the mains voltage returns to normal, the protector can automatically delay the power supply, restore power supply, all functions are automatically implemented, no personnel operation. The LEDs on the panel indicate the operating conditions of the protector. Indicator green light is the work of power instructions, the indicator light is not lit when the normal power supply, red light when the protection function to start cutting off power supply.
Self-resetting over-voltage protection is compact, beautiful appearance, and DZ47 (C45) rail universal.
Second, the self - complex over - voltage protection model and its meaning
Third, since the complex over-time protection device design principles
Automatic reset over-voltage undervoltage protection control circuit using high-speed micro low-power processor as the core, magnetic relay as the main circuit, modular design, when the power supply line over voltage, under voltage, the protector can Continuous high voltage impact quickly and safely cut off the circuit, to avoid abnormal voltage into the terminal electrical equipment caused by the accident, when the voltage returned to normal, the protector will automatically turn on the circuit within the specified time to ensure that the terminal electrical appliances in the case of unattended normal operation.
Four, self-resetting over-voltage protection product characteristics
◆ single-phase line when the over-voltage cut off the line, single-phase line voltage back to normal after the delay automatically reset the line, without manual operation.
◆ When the line is transient or transient overvoltage, the protector does not malfunction.
◆ line due to contact failure is not true voltage instability, or sudden power failure and a sudden call, the protector does not connect the line.
◆ When the line fault voltage is the highest, the protector itself will not be damaged.
◆ protector was anti-time action characteristics, action time ≤ 1s.
◆ voltage protection range: 40A the following 0 ~ 450V, 50 / 60A: 0 ~ 600V.
◆ withstand the impact voltage: 4kV (in line with Class III electrical safety standards).
◆ Protector has a two-color light-emitting diode indicates the working status, green - normal voltage indication; red - under-voltage or delay indication.
◆ Modular design of the shape, rail installation.
◆ Wiring capacity: 25 square millimeters and below insulated wire

Six, self-complex over-voltage delay protection protector shape and installation dimensions
Note: 4P self-complex over-voltage of the length of 72mm, other sizes and 2P the same.

Seven, self-repeated over-voltage delay protection precautions
★ protection device for the first time when the need to delay 1-2 minutes after the load to the normal power supply.
★ protector N line for the zero line, L for the line of fire, the protector is broken when the internal relay only cut off the L line, is strictly prohibited zero line and FireWire fault.
★ Please tighten the thread before use, to prevent bad contact and damage the product.
★ In order to ensure your personal safety and safety of electrical equipment, self-resetting over-voltage protection device before put into operation, please be sure to do: must be qualified by qualified personnel wiring operations, confirm the input power in a completely broken Open the case, in order to carry out wiring operations; in the installation must be carefully read the use of the manual; must be put into use under normal working conditions; before installing the current specifications and other parameters or function to meet the requirements;
8. Some questions about RMGQY-63 products
1, since the complex over-voltage protection device what role? What is the role?
Mainly used for low voltage protection, such as motor, the voltage is too low to start.
2, power over-voltage protection principle is what?
Power undervoltage overvoltage protector is by measuring the power supply voltage, set the voltage range within the relay, the output node. When the voltage is lower than the set value and higher than the given value, the relay action, used to cut off the power supply circuit.
3, since the complex over-voltage protection device is no matter how the power failure?
① undervoltage protector failure, or protector undervoltage protection set value set improper!
② can measure the voltage of the access terminal, if the voltage is normal, then the product failure, or within the product for breaking the relay pull-in voltage can not reach, can not pull, you can try true RMS measurement, the error is less than 1% product.
4, since the complex over-voltage protection device can replace the circuit breaker?
Of course not, because the two protected content is not the same. The main function of the circuit breaker is to break the short circuit current, both when a short circuit fault occurs, the circuit breaker will trip protection equipment. The effect of the undervoltage protector is to trip when the system voltage is detected below the set value.
5, self-complex over-voltage protection of the electrical clearance and creepage distance
The minimum clearance and creepage distance have a great relationship with the voltage and have a great relationship with the degree of contamination of the electrical surface and the shape of the charged body. The minimum clearance and creepage distance of the circuit breaker are known Rated voltage, so under the same voltage, the minimum electrical clearance and creepage distance should be the same. So here mainly to see the voltage level. The following options can be used as a reference
