A 22 mm Ampere Indicator is a compact panel-mount device designed to show current (amperage) flowing through a circuit. It’s used to monitor load current in control panels, distribution boards, machines, generators, and other electrical installations, helping operators quickly see if current is within safe limits or if there is an overload.

It is built with a standard 22 mm mounting hole — a widely used size for industrial and electrical panels — so it can be easily installed in existing control enclosures. Many versions use a digital LED display for clear visibility, often with built-in or external Current Transformer (CT) to measure AC current.

• Mounting hole / Panel cut-out size: 22 mm (standard for panel-mount indicators)  

• Current measurement range: Often 0–100 A AC (depending on model / CT) 

• Display type: LED digital display (red / green / multicolor, depending on variant) 

• Operating voltage: Typical AC supply (models vary — check product specs) 

• Working conditions: Ambient temperature range generally from about –25 °C to +55 °C for many 22 mm indicators

• Protection rating: Depends on model — often suitable for panel-mount applications; front-panel lens / housing may have basic ingress protection (for example IP20–IP55 in some variants) 

• Compact panel-mount size (22 mm): Easy to install in control panels, switchboards, distribution boxes, or machine enclosures.

• Real-time current monitoring: Lets users see current draw instantly — helpful for load monitoring, fault detection, overload prevention.

• Wide current range: Many models cover up to 100 A AC, suitable for motors, pumps, industrial loads, and general load circuits.

• Clear LED digital display: Easy to read from a distance under factory or workshop lighting conditions.

• Flexible installation: Can be used with or without an external CT (depending on model) — useful in retrofits or new installations.

• Durable build: Designed for long-term use in industrial / commercial electrical panels.

• Electrical control panels and distribution boards

• Motor control panels — pumps, compressors, fans, etc.

• Generator panels and backup power systems

• Industrial machines and process control equipment

• Workshop, factory electrical load monitoring

• HVAC systems, automation systems
