Product Description P/N: LRD16
Description
The LRD16 is a TeSys Deca thermal overload relay designed for integration with TeSys D contactors to form motor starters. These relays are compatible with TeSys D contactors ranging from 9 amps to 38 amps. They function by detecting overcurrents in motor supply lines. Upon detecting an overcurrent, the overload relay, in conjunction with the contactor, interrupts power to the motor, thereby preventing damage to its windings.

Information About LRD16
The LRD16 TeSys Deca thermal overload relay is an integral component designed for use in conjunction with TeSys D contactors to facilitate motor starting operations. Engineered to support TeSys D contactors ranging from 9 amps to 38 amps, these differential thermal overload relays serve the critical function of detecting overcurrents within motor supply lines. Upon detection of an overcurrent, the relay coordinates with the contactor to interrupt power supply to the motor, thereby safeguarding motor windings from potential damage.
The adjustable trip current rating of the LRD16 ranges from 9 to 13 amperes, aligned with Class 10A specifications. This calibrated trip current rating ensures precise and reliable operation under varying load conditions, enhancing overall motor protection. The LRD16 relay complies with multiple international standards, including IEC, UL, CSA, CCC, EAC, ATEX, and Marine certifications, underscoring its suitability for diverse industrial applications and global markets. Additionally, it meets Green Premium compliance standards, adhering to environmental regulations such as RoHs/Reach.
