Pointer Type AC 99T1 Analog Panel Gauge — Ampere Current Meter (1A–600A), 1Pc (300A/5A) Key benefits Provides a clear, immediate visual readout of AC current with a traditional pointer dial, allowing fast assessment of load conditions without waiting for digital processing. Wide selectable range support (1A to 600A) meets a variety of installation requirements; this listing is for the 300A (5A) variant suitable for use with a 300A/5A current transformer. Simple panelmount design integrates easily into control panels, switchboards, generators and motor control centers to improve monitoring and safety. What it does and why you need it Monitors AC current in real time, helping detect overloads, unbalanced loads, or abnormal operating conditions before they cause equipment damage or downtime. Works with standard current transformers (CTs) so you can measure currents with a compact panel instrument. The 300A(5A) model is matched for CTs with a 300A primary and 5A secondary. Analog pointer readout gives an intuitive, continually updated indication of current flow — ideal for operators who prefer immediate visual feedback. Key attributes Model: 99T1 Type: Pointertype analog panel gauge for AC current measurement Measurement range family: 1A to 600A (this unit: 300A(5A)) Quantity: 1 piece Display: Pointer dial for instantaneous readout Application compatibility: Designed for use with AC systems and compatible current transformers (e.g., 300A/5A CT) Mounting: Panel gauge format for straightforward installation into control panels Performance and reliability Analog pointer gives continuous indication with no lag from digital sampling; suitable for monitoring transient trends and steadystate loads. Rugged panel construction is intended for industrial panel environments (use appropriate mounting and wiring practices for specific installations). Typical applications Generator and transfer switch panels — monitor output current and detect overloads during load transfers. Motor control centers and industrial distribution boards — track motor starting and running currents to prevent overloads or detect faults. Transformer/CT secondary circuits and switchgear panels — used with a 300A/5A CT to display primary current on a compact panel instrument. What's included One (1) Pointer Type AC 99T1 Analog Panel Gauge, 300A(5A) variant. Installation notes (general) This is a panelmounted AC ammeter designed to be used with an appropriate CT. Verify CT ratio and wiring before installation. Follow local electrical codes and use qualified personnel for wiring and commissioning. Ensure CT secondary is properly burdened and protected when connecting to the meter. If you need a different range within the 1A–600A family, look for the corresponding 99T1 variant matched to your CT ratio.
