What is this product?
The Selec MA302 is a digital panel-mounted ammeter that measures and displays AC current in real time using a current transformer (CT) input. It's built for continuous, at-a-glance current monitoring on electrical panels.
Where is it used?
- LT/HT electrical distribution panels in factories and commercial buildings
- Motor control centers (MCCs) for monitoring motor load current
- DG (diesel generator) panels for load monitoring
- Industrial machinery panels (compressors, pumps, conveyors)
- Substation and switchgear panels for real-time current tracking
Key technical advantages
The MA302 stands out for its bright, high-visibility LED display that's readable even in poorly lit panel rooms — a common complaint with LCD-based competitors. Its 96×96mm form factor is a direct drop-in replacement for most existing analog and digital ammeter cutouts, saving panel rework. Selec's CT input handling is designed for stable readings even with fluctuating industrial loads, and the unit maintains accuracy across a wide ambient temperature range, making it reliable in non-air-conditioned panel enclosures common in Indian industrial settings.

FAQs
Q: What CT ratio should I use with the Selec MA302?
A: The MA302 typically accepts a 5A secondary CT input. You'll need to select a CT with a primary rating matching your actual line current (e.g., 100/5A, 200/5A) — our team can help you pick the right ratio based on your load.
Q: Can the MA302 replace an existing analog ammeter without changing the panel cutout?
A: Yes, the MA302's 96×96mm form factor matches standard analog ammeter cutouts, so in most cases it's a direct replacement without any panel modification.
Q: Does the MA302 work on both single-phase and three-phase systems?
A: The MA302 is designed for single-phase current measurement per unit. For three-phase monitoring, you'll need three units (one per phase) or a dedicated 3-phase multifunction meter — let us know your application and we can recommend the right configuration.
