LD63F600 | Siemens Molded Case Circuit Breaker

The LD63F600 is a Siemens molded case circuit breaker from the Sentron Series. It is a type LD, three-pole (3P), three-phase (3PH) device with a 600A current rating and 600V voltage rating. It has a standard interrupting capacity of 35kA at 480V. This circuit breaker features a bolt-on mounting type and operates at a temperature rating of 40 degrees Celsius. The LD63F600 is a thermal magnetic circuit breaker provided as a frame only, with lugs not included. 

The LD63F600 is a molded case circuit breaker manufactured by Siemens under the Sentron Series. This specific model is categorized under type LD and is designed for industrial applications. The breaker is a three-pole (3P) device intended for three-phase (3PH) electrical systems. It has a current rating of 600 amperes (A) and a voltage rating of 600 volts (V). The LD63F600 offers a standard interrupting capacity of 35kA at 480 volts. The thermal magnetic protection mechanism ensures reliable operation under various electrical conditions. 

The LD63F600 circuit breaker is designed with bolt-on connections, facilitating straightforward installation and secure attachment to compatible panels or mounting systems. This model is specified for a 40-degree Celsius operating environment, ensuring consistent performance within this temperature range. The unit is sold as a frame only, meaning that lugs for wire connections are not included and must be sourced separately if required for the application. 

The long-time and instantaneous (LI) functions of the LD63F600 provide dual protective capabilities. The long-time function is designed to handle prolonged overcurrent conditions, whereas the instantaneous function responds immediately to short-circuit events. This dual functionality is critical for maintaining the integrity and safety of electrical systems, particularly in industrial settings where load conditions can vary significantly.
