Core Technical Parameters

Core Product Advantages

1. High-Precision Protection, Stable and Reliable

The LRD-13 Thermal Overload Relay 0.063-0.1A employs a high-sensitivity bimetallic strip and precise calibration technology, accurately sensing micro-current changes within 0.063-0.1A. It quickly triggers protection in case of overload or phase loss, preventing burnout of the micro-motor windings. Silver alloy contacts reduce resistance and heat generation, while the flame-retardant housing enhances safety, making it suitable for the long-term high-frequency operation requirements of precision equipment.

2. Strong Compatibility, Easy System Integration

Supports direct mounting with LC1-D series contactors and standard DIN rail mounting. It is compatible with auxiliary contact modules (F4 series), time delay modules (LA2-DT), and other accessories, allowing for flexible configuration to suit different micro-automation systems without secondary modifications, reducing integration costs.

3. Compact Structure, Convenient Installation and Maintenance

The LRD-13 Thermal Overload Relay 0.063-0.1A is small and lightweight, saving over 30% of control cabinet space compared to traditional relays. It supports tool-free manual reset and trip testing, features clear wiring terminals, standardized installation dimensions, and can directly replace similar products from international brands, improving installation and maintenance efficiency.

4. High-Performance OEM Solution, Customizable

As a high-quality alternative to imported brands, it offers comparable performance at a 20%-30% cost reduction. OEM/ODM customization is supported, providing services such as parameter adjustment, logo printing, and packaging design to meet the brand and functional needs of global customers.

Real-world Application Case

German Precision Medical Equipment Production Line

In 2024, a German medical equipment manufacturer applied the GOTOELE LRD-13 Thermal Overload Relay 0.063-0.1A to the micro-motor protection system of a precision pipetting production line. The micro-drive motor (rated current 0.08A) of this production line operates for 12 hours daily, with 60-90 start-stop cycles, requiring extremely high overload protection accuracy.

Performance after 12 months of continuous operation:

- Zero product failures, accurate and stable trip protection;

- Completely eliminates motor burnout accidents caused by overload and phase loss;

- Compared to the original imported brand, equipment maintenance costs are reduced by 35%, and production line operating efficiency is increased by 20%.

Customer feedback indicates that GOTOELE micro-current relays demonstrate superior accuracy and reliability in precision equipment, fully meeting the high standards of the medical industry.

FAQ

Q1: Is the LRD-13 Thermal Overload Relay 0.063-0.1A suitable for all micro-motor protection scenarios?

A1: Primarily suitable for AC motors with a rated current of 0.063-0.1A (≤0.1kW), adaptable to continuous or frequent start-stop scenarios; not recommended for DC motors, ultra-high-speed motors, and equipment with large instantaneous impact loads. Parameters for special motors need to be confirmed in advance.

Q2: How to set the trip current and select the reset method?

A2: Trip current is set via the panel dial to match the motor's rated current; supports manual/automatic reset switching: manual reset is recommended for critical equipment to prevent accidental restart after a fault; automatic reset can be selected for unattended small equipment to simplify operation.
