シュナイダー EA9AN2C25 ミニチュアサーキットブレーカー

2 極, Type C tripping curve, 25A rated current, 6kA遮断容量, 230/400V AC rated voltage. Suitable for overload and short-circuit protection in residential, commercial and light industrial power distribution systems.

1. Model Breakdown

EA9AN2C25 = EA9AN (series code) + 2 (number of poles: 2P) + C (tripping curve) + 25 (定格電流: 25あ)

EA9AN: 標準 miniature circuit breaker from Schneider Easy9 series, slim design at 18mm per pole, high space utilization in distribution boards.

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

C: 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. Easy Operation: Fast make-and-break design minimizes arcing on contacts; intuitive operation, clear fault indication, and simple installation without complex commissioning.
6. 費用対効果が高い: High performance-to-price ratio for residential, retail and small office applications; full series compliant with national standards, flame-retardant and eco-friendly enclosure.
7. モジュラー設計: Can be assembled with Easy9 series surge protective devices, over/undervoltage accessories and other modules for expanded protection functions.
8. アプリケーション

Residential distribution systems: Protection for lighting and socket circuits in living rooms, bedrooms, 等.

Commercial buildings: Installation in distribution boards of small shops and offices.

Light industrial equipment: Auxiliary circuit protection in control cabinets.

Public facilities: Overload and short-circuit protection for lighting systems and small power equipment.

5. Selection & Replacement Recommendations
6. Application Matching

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

Recommended for resistive loads (e.g. 点灯) and general inductive loads (e.g. エアコン, refrigerators and other household appliances).

2. 代替モデル

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

Same-brand alternative: Acti9 series C65N2C25 (同様のパフォーマンス, compatible dimensions).

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

6. インストール & Usage Notes
7. 設置前, 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.
