TOMZN Phase Selector 3P+N 3*230V AC 63A Three-phase Separate Prepaid Function Adjustable Over Under Voltage Current Protection

TOVPD3-63VAEY Three-phase phase selector 3*220VAC 63AIndependent prepaid kWh management per phaseGeneralTOVPD3-63VAEY is three-phase phase selector. Its core purpose is to precisely measure electrical parameters, provide phase-selective prepaid kWh control, and safeguard connected equipment against common power anomalies.The device features a digital display for real-time monitoring of operating voltage, current, and kWh consumption. A key innovation is itsindependent prepaid kWh management per phase, allowing users to set individual energy credits for Phase A, B, and C according to specific needs. When the credit on one phase is exhausted, the system automatically switches the supply to the next phase in sequence.It offers comprehensive protection by automatically disconnecting loads in case ofover-voltage(adjustable 230V-300V),under-voltage(adjustable 140V-210V), andover-current(adjustable 3A-63A). Protection actions can be customized with configurable delay times and automatic/manual recovery modes.TECHNICAL DATARated supply voltage: AC220VMax load current: 63ACurrent protection:3-63A adjustableOperation voltage range: AC140V-300VRated frequency：50/60HzHysteresis:Over voltage and asymmetry:5V, Under voltage:5VAsymmetry trip delay: 10sVoltage measurement accuracy: ≤1%(over the whole range)Rated insulation voltage: 450VOutput contact: 1NOElectrical life:100000Mechanical life: 100000Protection degree: IP20Pollution degree: 3Altitude: ≤2000mHumidity: <50% at 40℃(without condensation)
