The recommended wiring configuration for the L1452M is a star configuration, where each phase is connected to a separate terminal on the meter. This ensures accurate measurement of voltage and current.
Yes, the L1452M can be used in a 3-phase 4-wire system. However, it requires a neutral current transformer (CT) to be installed in addition to the phase CTs.
The L1452M has built-in overcurrent protection, which triggers an alarm and/or a relay output when the current exceeds a set threshold. The meter can also be configured to trip a circuit breaker or disconnect the load in case of an overcurrent condition.
The L1452M is designed to operate in temperatures ranging from -25°C to 70°C. However, it's recommended to derate the meter's accuracy and reliability in high-temperature environments above 55°C.
The L1452M should be calibrated every 1-2 years, depending on the application and environmental conditions. Calibration ensures the meter's accuracy and reliability.
