1. Model Breakdown

EA9AN2C25 = EA9AN (series code) + 2 (number of poles: 2ป) + ค (tripping curve) + 25 (จัดอันดับปัจจุบัน: 25ก)

EA9AN: มาตรฐาน เบรกเกอร์วงจรขนาดเล็ก from Schneider Easy9 series, slim design at 18mm per pole, high space utilization in distribution boards.

2ป: 2-pole protection, disconnects both live and neutral wires for enhanced electrical safety.

ค: Type C tripping characteristic, tripping range 5–10×In, suitable for general loads such as lighting and sockets.

25: Rated current 25A, stable operation at 30℃ ambient temperature.

5. Selection & Replacement Recommendations
6. Application Matching

Suitable for load circuits with total power ≤5.5kW (230วี) or ≤17kW (380วี).

Recommended for resistive loads (e.g. lighting) and general inductive loads (e.g. เครื่องปรับอากาศ, refrigerators and other household appliances).

2. โมเดลทางเลือก

Upgraded within the same series: EA9AH2C25 (10kA breaking capacity, for higher short-circuit risk environments).

Same-brand alternative: Acti9 series C65N2C25 (similar performance, compatible dimensions).

Domestic brand alternatives: CHINT NXB-63 2P C25, DELIXI DZ47s 2P C25 (ต้นทุนที่ต่ำกว่า, comparable performance).

6. การติดตั้ง & Usage Notes
7. ก่อนการติดตั้ง, verify the model matches load requirements and check rated current and number of poles.
8. Install in dry, ventilated environments, away from high temperatures, humidity and corrosive conditions.
9. Ensure conductors meet specifications during wiring, with proper torque to avoid overheating from loose connections.
10. Inspect the breaker regularly to ensure flexible operation, no damage or overheating.
11. After a fault trip, identify and resolve the cause before resetting; avoid repeated closing without troubleshooting.
