The LV847507 is a PTE voltage measurement input module for MasterPact MTZ1 drawout circuit breakers. It's a trip-unit accessory that feeds voltage sensing to the MicroLogic trip unit — the brains of the breaker's protection and metering. Drawout mounting means the module slides into the breaker cradle, not the fixed chassis. That's the standard for switchgear where you need to rack the breaker out for maintenance without killing the bus.
Voltage range and what it covers
Primary circuit accepts up to 1250 V AC at 50/60 Hz; secondary side handles 100 V AC minimum to 690 V AC maximum. The control circuit itself runs on 100 V AC minimum on both primary and secondary sides. No 24 V DC option here — this is pure AC-sourced voltage measurement.
