📌 Selection Differentiation (致命的)

MGNEA9C45C1630C: ACタイプ, only detects AC leakage; for pure resistive lighting & ソケット回路

MGNEA9C45C1630CA: タイプA; preferred for phone chargers, inverter air conditioners, 給湯器, water purifiers, small EV charging circuits (mandatory for modern residential electrical installations)

📍 Typical Application Scenarios

Residential indoor socket circuits, 台所 & bathroom circuits, single-phase power distribution in small retail premises.

Not suitable for direct-on-line starting of high-power motors.

⚠️ Replacement Options

1. Direct same-series replacement: MGNEA9C45C1630CA (タイプA)
2. Domestic equivalent alternatives: Chint NXBL-32 1P+N C16 30mA Type A; Delixi HDBE-40LE, 等.
3. Upgraded Schneider series: iC65N Vigi (iC65N + separate residual current attachment, 6kA遮断容量)

📋 Troubleshooting Guide

1. 閉店直後の旅行: Earth leakage fault (Type A is more sensitive to DC leakage), or live-neutral cross-connection
2. Intermittent tripping under load: Minor line-to-earth leakage, or internal power supply board leakage from connected equipment
3. Cannot close the switch: Short circuit or overload; disconnect downstream loads before retesting
4. テストボタン (T): Press once per month; the breaker should trip normally

Schneider MGNEA9C45C1630CA (EA9C45 1P+N C16 30mA Type A) vs Other Brands’ 1P+N RCBOs

Product positioning: Easy9 contractor-grade integrated RCBO, electronic Type A, 4.5kA遮断容量, 2 モジュール (36mm), neutral pole non-switched

Comparison scope: Chint NXBL, Delixi HDBE, ルグラン, Siemens 5SU1, ABB 1P+N RCBOs

1. Common Structural & Wiring Characteristics (All 1P+N Models)

✅ Shared features: Only the live (L) pole is disconnected during tripping; 中性 (N) pole remains continuous. The neutral pole has no overload/short-circuit protection. Strict L/N polarity is required; polarity reversal is forbidden. All models are 2-module (36mm) DIN rail mounted, 30mA instantaneous trip, Cカーブ.

⚠️ This is an inherent design of 1P+N breakers, not exclusive to Schneider. It differs fundamentally from 2P RCBOs (which cut both live and neutral poles).

2. Key Differences Between Brands

(1) 残留電流タイプ (Most Common Pitfall)

This Schneider model: タイプA (CA suffix). Detects both AC leakage and pulsating DC leakage; compatible with chargers, inverter AC, LED drivers, small EV chargers and switch-mode power supplies. This is the standard Type A required for modern residential & high-end renovation projects.

Many entry-level domestic 1P+N breakers: Default Type AC, only responding to sinusoidal AC leakage. They will fail to trip when DC leakage occurs from electronic loads, creating hidden safety risks.

(2) C Curve | ACタイプ (C suffix, legacy model for pure AC loads)

(3) D Curve | タイプA (CA suffix, for motors & impulse loads)

(4) Derived K-type (Both live & neutral poles switched, ACタイプ)

Phase-out Notice

1. Old part numbers without the MGN prefix (EA9C45C1630C) have been upgraded to the new MGNEA9C45 range.
2. Low-current Type AC variants are gradually being discontinued. New projects are recommended to specify CA Type A.
