## Summary description

Analog ammeter BLOW 4640# is designed for measuring direct current up to 30 A and includes an external shunt for accurate measurements. The instrument provides a simple analog needle display for monitoring current in electrical circuits, panels or distribution boards. Suitable for industrial and residential installations where visual, real-time current indication is required.

## Long description

Analog ammeter BLOW 4640# is an analog needle instrument for measuring direct current up to 30 A and is supplied with an external shunt for accurate readings. The panel/clamp mount design allows installation in control panels, distribution boards or on mounting plates where a clear, continuous visual indication of DC current is needed. The instrument provides a simple, readable scale and robust mechanical movement suitable for industrial and residential electrical applications.
Advantages
The ammeter delivers direct current measurement with a mechanical pointer, offering immediate visual feedback without the need for power-up or digital processing. The included external shunt improves measurement accuracy and enables the instrument to handle higher currents while protecting the movement. The panel/clamp mounting system simplifies installation and allows integration into existing panels or enclosures. The device is designed for stable readings and long-term mechanical reliability under normal environmental conditions.
Suitable for
Monitoring DC current in control panels and distribution boards
Use in industrial machinery and equipment with DC circuits
Battery systems and photovoltaic installations for current monitoring
Residential and commercial electrical panels requiring visual current indication
Key specifications
Measurement type: direct current (DC)
Full-scale range: up to 30 A
Display: analog pointer with graduated scale
Mounting: panel or clamp mount suitable for enclosure installation
Shunt: external shunt included for accurate high-current measurement
Construction: mechanical movement with protective housing
How to use
Install the ammeter in a prepared panel cutout or secure it using the clamp mounting hardware. Connect the external shunt in series with the load according to the polarity markings and wiring recommendations, then connect the ammeter input across the shunt terminals. Ensure all connections are tight and properly insulated. After installation, observe the analog pointer when the circuit is energized to monitor DC current; routine visual checks will indicate normal operation or the presence of overloads.
Usage recommendations
Place the instrument where the scale is easily visible and protect it from direct exposure to moisture and excessive dust. Verify shunt connections periodically and avoid exceeding the rated current. For environments with vibration or shock, ensure secure mounting and check calibration if precise readings are required.
