📌 Selection Differentiation (Critico)

MGNEA9C45C1630C: Tipo AC, only detects AC leakage; for pure resistive lighting & circuiti di prese

MGNEA9C45C1630CA: Tipo A; preferred for phone chargers, condizionatori inverter, scaldabagni, water purifiers, small EV charging circuits (mandatory for modern residential electrical installations)

📍 Typical Application Scenarios

Residential indoor socket circuits, cucina & 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 (Tipo A)
2. Alternative equivalenti domestiche: Chint NXBL-32 1P+N C16 30mA Type A; Delixi HDBE-40LE, ecc.
3. Upgraded Schneider series: iC65N Vigi (iC65N + separate residual current attachment, 6potere di interruzione kA)

📋 Troubleshooting Guide

1. Viaggi subito dopo la chiusura: 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. Pulsante di prova (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, 4.5potere di interruzione kA, 2 moduli (36mm), neutral pole non-switched

Comparison scope: Chint NXBL, Delixi HDBE, Legrand, 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; neutro (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) Montaggio su guida DIN, 30mA instantaneous trip, Curva a C.

⚠️ 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) Tipo di corrente residua (Most Common Pitfall)

This Schneider model: Tipo A (CA suffix). Detects both AC leakage and pulsating DC leakage; compatible with chargers, inverter AC, Driver LED, 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.

Avviso di eliminazione graduale

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.

Guida alla selezione rapida

1. General sockets, kitchen/bath circuits, inverter appliances → C curve + CA (Tipo A)
2. Pure resistive incandescent lighting loads → Type C (AC) is acceptable
3. Pompe dell'acqua & small motors → D curve + CA (Tipo A)
