Schneider Electric TeSys GV3L40 Thermal Magnetic Circuit Breaker 3-Pole 40A 690V DIN Rail Mount
The Schneider Electric TeSys GV3L40 is a high-performance 3-pole thermal magnetic circuit breaker engineered specifically for reliable motor protection. Designed to handle demanding industrial environments, this device supports 3-phase motor applications up to 18.5kW at 400V. It features a robust construction with a 40A current rating and a 690V voltage rating, ensuring consistent performance in 50/60 Hz AC systems. The unit is designed for efficient DIN rail mounting, making it an ideal component for integration into industrial control panels and motor starter assemblies.
This circuit breaker offers exceptional durability and ease of use through its advanced EverLink terminal technology, which provides a sturdy and long-lasting power connection. The device is built for longevity, with a rotary handle control mechanism tested for up to 50,000 cycles under AC-3 conditions. Its design prioritizes installation efficiency, utilizing multi-standard screws that simplify the setup process. Furthermore, the high breaking capacity of 50kA at 400V ensures superior protection against short circuits, while the magnetic tripping level at 14 times the rated current provides precise response to electrical faults.
This device is not suitable for applications requiring thermal overload protection as a standalone unit, as it provides magnetic protection only. For complete motor protection, it must be used in conjunction with a compatible thermal overload relay.
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a control cabinet. Ensure that the power supply is disconnected before beginning the installation. Connect the power cables securely to the EverLink terminals, ensuring the torque specifications are met to maintain a reliable connection. Once mounted, the rotary handle allows for manual start-stop control of the connected motor.
For optimal performance and safety, it is recommended to pair this circuit breaker with a thermal overload relay such as the LRD340 to ensure comprehensive motor protection against both short circuits and thermal overloads.
