Schneider Thermal Overload Relay LRD14

The Schneider Thermal Overload Relay LRD14 is a device that protects three-phase motors against overloads. It is a differential thermal overload relay, which means that it uses two sensors to measure the current in each phase of the motor. If the current in any phase exceeds the set threshold, the relay will trip and disconnect the motor from the power supply.

The LRD14 has a thermal setting range of 10 to 16 A and a tripping class of 10 A. This means that it can be used to protect motors with a maximum current of 16 A. The relay is also certified to IEC, UL, CSA, CCC, EAC, ATEX, and Marine standards.

The LRD14 has a number of features that make it a versatile and reliable device for motor protection. These features include:

• A manual-automatic reset selector
• A test selector for simulating a tripping event
• A flag indicator to show the status of the relay
• Two auxiliary contacts for fault signaling
• A transparent cover that protects the settings

The LRD14 is easy to install and use. It can be mounted on a DIN rail or screwed directly to the contactor. The relay is also compatible with a wide range of contactors, including the Schneider Electric LC1D09-D38 series.

The LRD14 is a reliable and versatile device that can be used to protect three-phase motors against overloads. It is certified to a number of international standards and is compatible with a wide range of contactors. The LRD14 is a valuable tool for any electrical engineer or technician who is responsible for the safety and operation of motors.

Here are some additional benefits of using the Schneider Thermal Overload Relay LRD14:

• Improved safety: The LRD14 can help to prevent motor fires and other accidents by tripping the motor if it overheats.
• Increased uptime: The LRD14 can help to prevent motor downtime by protecting the motor from damage.
• Reduced costs: The LRD14 can help to reduce the cost of motor repairs and replacements by preventing damage.

If you are looking for a reliable and versatile thermal overload relay to protect your three-phase motors, the Schneider Thermal Overload Relay LRD14 is a great option. It is easy to install and use, and it is certified to a number of international standards. The LRD14 is a valuable tool for any electrical engineer or technician who is responsible for the safety and operation of motors.

Here are some additional features of the Schneider Thermal Overload Relay LRD14:

• Phase failure detection: The LRD14 can detect if one or more phases of the motor have failed. This can help to prevent damage to the motor and other equipment.
• Load unbalance detection: The LRD14 can detect if the load on the motor is unbalanced. This can help to prevent damage to the motor and other equipment.
• Overtemperature protection: The LRD14 has an internal thermistor that can detect if the motor has overheated. This can help to prevent damage to the motor and other equipment.

The Schneider Thermal Overload Relay LRD14 is a versatile and reliable device that can be used to protect three-phase motors against a variety of hazards. It is easy to install and use, and it is certified to a number of international standards. The LRD14 is a valuable tool for any electrical engineer or technician who is responsible for the safety and operation of motors.
