Selection Guide
- Determine rated current: Select a meter with a full-scale rating slightly higher than the maximum operating current of the circuit.
- Choose connection method:
- For circuits ≤50A: direct-connection ammeter models are available.
- For circuits >50A: select an ammeter with a current transformer ratio matching your CT specification (e.g. 200/5A meter paired with 200/5A CT).
- Confirm CT secondary rating: Standard options are 5A secondary or 1A secondary; ensure the meter matches your CT output.
- Verify panel dimensions: Ensure your panel has a 76×76mm mounting opening compatible with the 6L2 form factor.
- Custom requirements: Custom dial scales, special CT ratios and OEM logo printing are available for volume orders.
Installation & Maintenance Instructions
Installation
- Fully de-energize the target circuit and confirm zero voltage before starting any wiring work.
- Insert the ammeter into the pre-cut panel opening from the front side.
- Secure the meter from the rear using the supplied mounting brackets and fixing screws.
- For direct-connection models: connect the meter in series with the measured circuit.
- For CT-operated models: connect the meter terminals to the current transformer secondary circuit. Critical safety note: never leave the CT secondary circuit open while the primary circuit is energized.
- Restore power and verify normal pointer deflection against expected load values.
Maintenance
- Clean the dial cover periodically with a soft, dry cloth to maintain clear visibility.
- Inspect terminal connections regularly for tightness and signs of overheating or corrosion.
- For CT-operated installations, periodically verify CT secondary circuit integrity and grounding.
- Avoid prolonged exposure to direct sunlight, high humidity, excessive dust or corrosive atmospheres.
- Recalibration every 2–3 years is recommended to maintain measurement accuracy, especially for high-current and critical monitoring applications.
- All electrical installation and maintenance work must be performed by qualified personnel in compliance with local electrical safety regulations.

Frequently Asked Questions (FAQ)
Q: Can the 6L2 ammeter measure DC current?
A: No. The standard 6L2 ammeter is designed exclusively for alternating current (AC) systems. DC-specific variants with different internal structures are available as separate product models.
Q: Do I need a current transformer for a 50A 6L2 ammeter?
A: 50A and lower ratings can be supplied as direct-connection models. For all current ratings above 50A, a matching current transformer (CT) is required. The meter dial is scaled to correspond with the CT secondary output (typically 5A or 1A).
Q: What does accuracy class 1.5 mean?
A: Class 1.5 indicates a maximum permissible measurement error of ±1.5% of the full-scale value, which meets the standard requirements for general industrial monitoring and indication applications.
Q: What is the mounting hole size for the 6L2 ammeter?
A: The standard panel cutout dimension is 76mm × 76mm, with an overall front bezel size of 80mm × 80mm, compatible with all standard 6L2-format panel openings.
Q: What is the difference between 5A secondary and 1A secondary ammeters?
A: These refer to the rated secondary current of the matching current transformer. 5A secondary is the most common industry standard, while 1A secondary is often used for longer wiring distances or specific system designs. The meter must match the CT secondary rating.
Q: Can this meter be used outdoors?
A: The standard 6L2 ammeter has an IP40 front protection rating and is intended for indoor use inside enclosed electrical panels. Outdoor installation requires an additional weatherproof protective enclosure.
