Current Status Switch With Split Core For VFD Motors, Hawkeye H904 Microprocessor Based Amperage Monitor With Non Volatile Memory, Normal Open Output, Real Time Motor Current Status Sensor For Shop Floor Use
UPC:
✔️ Includes relay option; available as single unit or 2-pack
This current status switch is designed to monitor motors controlled by variable frequency drives. It's typically used on shop floors to verify motor status and quickly flag belt or coupling issues before they cause downtime.
✅ Split-core design for easy retrofits; no conductor removal
✅ Monitors motor current and frequency to separate normal dips from faults
✅ Factory-programmed trip point detects belt loss or coupling shear under load
✅ Optional relay included; status and control in one package
✅ Three mounting configurations for flexible shop floor installation
✅ 5-year limited warranty
✅ Sensor power induced from monitored conductor; 600VAC RMS insulation
✅ Frequency ranges: 20-34 Hz for on/off, 34-75 Hz for belt loss indication
✅ Temperature range -15°C to 60°C; 10-90% RH non-condensing
✅ Off delay adjustable 0 sec to 2 min; 14 AWG terminal block; 4 in-lbs torque
✅ UL 508 open device listing approvals
💡 What is a split-core current status switch for VFD motor monitoring and how does it work? This handy sensor uses a split-core clamp to monitor a live conductor without disconnecting it and compares amperage to stored baselines across frequency ranges to detect abnormal load conditions. - It clamps around a single conductor to sense current - Stores baseline amperage across different frequency ranges in non-volatile memory for accurate fault detection - Triggers a relay output and status signals to control systems on abnormal conditions
