The Littelfuse Startco SE-330AU-01-00 is a neutral-earthing-resistor monitor with a 120/240 Vac/Vdc supply.
It provides earth-fault and earthing-resistor monitoring: neutral current, neutral-to-earth voltage and neutral-to-earth resistance; detects NER failure with or without an earth fault present.
Settings: GF trip level 0.125 to 30 A (0.125 to 5 A with 5-A-primary CT, 0.75 to 30 A with 30-A-primary CT); GF trip time 0.1 to 0.5 s; Vn trip level 20-2,000 Vac (≤5 kV systems), 100-10,000 Vac (>5 kV systems). Applications: 35 kv or less. Sensing: current transformer required (EFCT series 5 A primary or SE-CS30 series 30 A primary); ER series sensing resistor (required).
Outputs: two Form A, two Form C. Analog output: 4-20 mA, self or loop powered. Communications: Mini USB (standard); DeviceNet. Indication: Open-CT detection; micro SD data logging. Harmonic filtering: standard feature (DFT).
Mounting: panel, surface (optional). Size: H 213 mm (8.4”), W 98 mm (3.9”), D 132 mm (5.2”). Conformally coated as standard.
Approvals: RCM (Australian), CE.
