Review SQUARE D Squarea4a101 Nos New Old Stock 1/2 Inch Ac Ammeter 60hz

Introducing the Square A4A101 Nos 1/2 AC Ammeter, a precision instrument designed for measuring alternating current flow in electrical circuits. This ammeter, with the model number 007-079A, is a must-have tool for electricians, technicians, and hobbyists who require accurate and reliable current measurements in their projects.

The Square A4A101 Ammeter is a half-inch dial type ammeter, which means it features a large, easy-to-read dial with a diameter of 1.5 inches. The dial is divided into 60 graduations, allowing for precise measurements up to a maximum of 100 Amperes. The ammeter operates on a 60 Hz frequency, making it suitable for measuring current in most common electrical applications.

The ammeter is designed for use in AC circuits, and it features a shunt resistance of 0.01 Ohms. This low resistance ensures minimal voltage drop across the shunt, resulting in highly accurate current readings. The ammeter is also calibrated to provide a full-scale deflection at 100 Amperes, ensuring that even small current measurements can be accurately read.

The Square A4A101 Ammeter is housed in a rugged, die-cast aluminum case that provides excellent protection against shock and vibration. The case is also sealed to prevent the intrusion of moisture or dust, making the ammeter suitable for use in a variety of industrial and laboratory environments.

The ammeter comes with a pair of test leads and a shunt, which are necessary for making accurate current measurements. The leads are made from high-quality copper wire, and they are insulated with tough, flexible PVC material to ensure longevity and durability. The shunt is also designed for long-term use, with a robust construction that can withstand the demands of heavy current measurements.

In summary, the Square A4A101 Nos 1/2 AC Ammeter 0-100A 60Hz 007-079A is a high-performance, accurate, and reliable instrument for measuring AC current. Its large, easy-to-read dial, rugged construction, and low resistance shunt make it an essential tool for electricians, technicians, and hobbyists. With its precision measurements and robust design, the Square A4A101 Ammeter is a worthwhile investment for anyone who requires accurate current readings in their work.
