This robust and durable device performs well in areas where other devices struggle to achieve it, and can operate reliably even in cold temperatures and high-altitude regions. Its sturdy structure can resist the corrosive effects of severe sandstorms and coastal humidity. Red 3P provides continuous and reliable surge protection for sensitive equipment under various harsh conditions

Overvoltage and undervoltage protectors are mainly used in the incoming lines of residential household distribution boxes or distribution lines that need to protect single-phase electrical equipment, such as power supply systems in homes and small offices, providing overvoltage and undervoltage protection for various electrical equipment such as air conditioners, refrigerators, and televisions.Generally installed at the incoming line of the household distribution box in a residential building or at the front end of the distribution line where single-phase electrical equipment needs to be protected.

1.Overcurrent protectionvalue can be set by yourself. Electrical appliances use too much electricity, causing wires to heat up Cause fire electrical occurrence, the protection can Cut off the power at0.1 seconds to prevent a fire,Troubleshooting recovers itself.

2.Leakage protection Keep your family safeThe electrical leakage at home prompts the mobile software to issue a warning, and it is important to promptly eliminate the electrical leakage hazard.

Photovoltaic automatic reclosing has the function of automatically closing when there is power and automatically opening when there is a power outage. It also has the function of fault-proof closing, overload and lightning protection. It is suitable for automatic opening and closing control of the line in the circuit of AC 1P+N 45 width, 1P+N 108 width, and rated current 1A-63A. This product is widely used in photovoltaic and mains grid-connected systems. When the mains power supply circuit breaker automatically recloses to realize the parallel use of mains power and photovoltaic power generation, when the mains power is cut off, the circuit breaker automatically disconnects to block the parallel connection of mains power and photovoltaic power (popular saying: close when there is power, disconnect when there is no power), and is used in places where personnel are difficult to access and where maintenance personnel cannot be in place in time. It can also be used for infrequent line operation conversion. Automatic mode: The circuit breaker automatically closes when there is power in the main circuit and automatically opens when there is a power outage. Manual mode: When there is power in the main circuit, the circuit breaker automatically adjusts the opening state and will not automatically close to ensure the safety of circuit maintenance.

.Overvaltage 130V~300V, undervoltage 80V~210V, It is always under protection upon incorect setting.and fault lamp is on.
.Abnormal ignition of front-end power,power failure and other protector actions.
.After manual protection tums off the output, it must be tumed on manually.
.When the protection function is tured off, the relay remains as it is and no longer acts, but the switchbutton is still active.
.Voltage, current, frequency, visual power, etc. are switched according to mode.
. Prevent the parameters from baing modified by mistake, which cannot achieve the purpose of protection.
.When DC is used, current / power is invalid.
.Reduce the brightness of digital tube to save energy when the protector ls not active. 
.The system performance and stabllity are improved and the system has high maintainabllty.

The 275V lightning surge protector (SPD) is an overvoltage protection device used in low-voltage electrical systems. Its core function is to protect against surge voltages caused by lightning or abnormal grid conditions, ensuring the safety of equipment. The specific usage functions are as follows:

Surge voltage interception: When an instantaneous overvoltage exceeding 275V occurs in the circuit (such as surges generated by lightning induction or grid switch operations), it can quickly conduct and discharge the excessively high voltage to ground, preventing equipment from being damaged by breakdown.

Normal circuit maintenance: When the grid voltage is normal (not exceeding 275V), maintain a high-impedance state to ensure normal power supply to the circuit and stable operation of the equipment.

Overload protection and indication: Some models are equipped with overload protection function. When the surge current is too large, it will automatically disconnect to prevent self-damage. At the same time, the working status (such as normal or faulty) is indicated through indicator lights and other means, facilitating maintenance.

DC500V DC lightning protection is a lightning surge protection measure designed for electrical systems with a DC voltage of 500V. The core is achieved through dedicated DC lightning surge protectors (SPDS). Its main functions and features are as follows:

Blocking DC surge: When instantaneous overvoltage occurs in the DC system due to lightning induction, equipment start-up and shutdown, power switching, etc., the protector quickly conducts to discharge the surge current to ground, preventing overvoltage from damaging DC equipment 

Adapted to DC characteristics: Specifically designed for DC systems, it can withstand a 500V DC working voltage, preventing false operation under normal DC voltage. It also features unidirectional conduction or symmetrical protection capabilities, adapting to the polarity characteristics of DC circuits.

Ensure system stability: During normal operation, it presents a high-impedance state, which does not affect the normal power supply of the DC system and the operation of equipment. Automatically restore high resistance after the surge to ensure the continuous stability of the system.

Fault Indication and Protection: Some models are equipped with status indicators (such as indicator lights) to facilitate the determination of whether they are working properly. When encountering large surges or self-damage, it will automatically disconnect to avoid affecting the entire DC system.
