40A 230V DIN Rail Adjustable Over/Under Voltage Protective Relay

Types of the Over/Under Voltage Protector
The 40A 230V DIN Rail Adjustable Over/Under Voltage Protector is a multifunctional protective relay that integrates several key safety features:
• Overvoltage Protection: Protects equipment that is connected from receiving excess voltage.
• Undervoltage Protection: Helps to prevent equipment degradation or substandard performance brought about by low voltage environments.
• Overcurrent Protection: Interrupts the circuit whenever a high amount of current pass through the system which again will not allow any overloading of the circuit or overheating of any component involved in conducting electricity.
Whenever any of these faults is identified the protector switches off the power to prevent the connected devices from getting damaged. Once the fault is removed, and the electrical parameters are back to normal, the protector switches back and reconnecting the circuit to enable the system to perform its expected function.
This protective relay serves a great purpose especially for domestic, commercial and industrial uses where voltage instability results to system interruptions or damages to equipment. Another feature of the device is automatic resetting to normal mode, meaning that even when the configuration stabilizes there is no need for intervention to turn the power back on, thus saving time while protecting the equipment.

Key Features
The 40A 230V DIN Rail Adjustable Voltage Protector is developed with high official protection features which make it to work at its best in any setting. Its key features include:
• Overvoltage Protection: This relay function can monitor and disable the power when voltage is beyond the set range (standard is 270VAC, with the range of 240VAC-300VAC).
• Undervoltage Protection: If voltage goes lower than certain level (standard 170VAC, range: 140VAC-200VAC), the protector turns off the circuit to protectequipment from operating with inadequate power.
• Overcurrent Protection: While having adjustable current settings the device is switched off when the current of the circuit is more than set (by default 40A for 40A version and 63A for 63A version). The response time may be set to avoid false alarms during short power fluctuations.
• Adjustable Parameters: Overvoltage, undervoltage, and overcurrent parameters and power restoration delay time can also be adjusted to reflect local environment conditions and characteristics of electrical equipment. This makes sure that the system runs as intended, and with optimum security, especially from frequent interferences.
• Self-Resetting Function: Once a fault has been sorted out the protector resets and reinstate the circuit after a certain time period which can be set between 5 to 300 seconds with a default value of thirty seconds.
• Transient Overvoltage Immunity: They will not operate during brief, non-critical voltage transients thereby minimizing unnecessary trips.
• Digital Display: There are two digital displays on the device that display voltage and current which help the users to control system conditions.
• Compact Design for DIN Rail Mounting: The protector can be mounted on a conventional 35mm DIN rail for ease of installation making it easily incorporable into most electrical control panels.

Technical Parameters
Here are the technical specifications of the 40A 230V DIN Rail Adjustable Over/Under Voltage Protector:
• Rated Voltage: 220VAC, 50Hz.
• Rated Current: It can be set between 1A-40A (standard: 40A).
• Overvoltage Cut-Off Value: Rangable between 240V-300VAC are set to default at 270VAC.
• Undervoltage Cut-Off Value: Controls for voltage range from 140V-200VAC with the standard at 170VAC.
• Overcurrent Cut-Off Value: Protected current range is variable from 1A-40A for the 40A model or 1A to 63A for the 63A model.
• Power-On Delay Time: The FLC can be set between 1 second and 5 minutes (by default, it was set at 5 seconds).
• Power Restoration Delay Time: Can be set between 5 to 300 seconds, by default it is 30 seconds.
• Reset Delay Time after Overcurrent Protection: Range from 30 to 300 seconds depending with the user's preference Twenty seconds equivalent to this parameter's default value.
• Overcurrent Protection Delay: It should be noted that any overcurrent for period longer than 6 seconds will cause tripping of the protection.
• Power Consumption: Less than 2W.
• Electrical & Mechanical Life: Over 100,000 operations.
• Dimensions: 3.21 x 1.38 x 2.36 inches (specially designed to be small to fit almost anywhere).

Installation Guidelines
The 40A 230V DIN Rail Adjustable Voltage Protector can be mounted either in the vertical position or in the horizontally according to the need of the circuit. This ensures it can be easily installed on a regular 35mm DIN rail which is mounted in most electrical enclosures in residential/commercial/industrial applications. Here are recommended installation conditions:
• Ambient Temperature: The protector functions most efficiently at a temperature of between -10?C and 50?C.
• Altitude: Designed to be installed at places with an altitude of up to 2000 meters above sea level.
• Humidity: Maximum allowed relative humidity is 60 percent.
• Pollution Degree: It has a Pollution Degree 3 certification so that the equipment proves adequate in mildly polluted environments.
• Non-Explosive Atmospheres: Explosive gases or conductive dust must not be present when it is being installed since such environments will negatively affect the functionality and safety of the device.
It should also be fixed at a place that does not exposed to rainfall or snow to remain functional in all seasons.
