The Eaton Cutler-Hammer LDC3500 is designed as a highly effective molded case circuit breaker. Engineered for three-phase electrical systems, it features an L-frame capacity and is rated for a current of 500 Amps. This model is capable of handling an input voltage of 600 VAC in AC scenarios and up to 250 VDC for direct current applications.
In terms of reliability, the LDC3500 showcases impressive interrupting capabilities, rated at 65 kAIC for circuits operating at 240 VAC and reaching up to 100 kAIC for 480 VAC applications. This makes it suitable for a range of industrial uses where high fault currents may occur. The breaker exhibits two significant trip functions: long-time (LI) and instantaneous, which enhances safety by responding appropriately to varying electrical conditions.
Reliability is further assured through a thermal-magnetic trip unit which offers precise operation under different load factors. Additionally, the unit functions optimally within a frequency range from 50 Hz to 60 Hz, ensuring compatibility with most industrial systems. The LDC3500 circuit breaker is a critical component for controlling electrical distribution, providing extensive protection and efficient performance in varied environments.
