The LRD16 by Schneider Electric functions as a thermal overload relay, crucial for safeguarding motors against potential damage due to overheating. This relay operates effectively within a thermal overload class of 10A, adhering to the IEC 60947-4-1 regulation.
Designed to accommodate an adjustment range between 9 and 13 Amps, the LRD16 operates across a network frequency of 0 to 400 Hz. The relay has the capability to maintain an auxiliary contact composition of 1 normally open (NO) and 1 normally closed (NC), enhancing its versatility.
With a conventional free air thermal current rating of 5 Amps and robust dielectric strength at 1.89 kV for 50 Hz applications, this relay is built for reliability. The rated impulse withstand voltage is 6 kV, ensuring durability even during transient conditions in the electrical circuit.
This device is rated for operation at up to 690 V AC and weighs in at a compact 0.124 kg, enabling simple installation. Its dimensions measure 66 mm in height, 45 mm in width, and 70 mm in depth, making it suitable for confined spaces. The LRD16 is designed to perform within a permissible current of 1.5 A at 240 V AC. Its degree of protection is IP20, which provides adequate defense against solid objects larger than 12 mm but does not offer protection against water. For operation, the ambient temperature range is specified from -20 to 60 °C, making it adaptable to a variety of environments.
