التصنيف الحالي في: 63 أ

البولنديين: 2ص (مرحلة واحدة)

Rated voltage Ue: 230 الخامس و, 50 هرتز

تيار التشغيل المتبقي: 30 أماه, رحلة فورية

نوع الرحلة: الكترونية (ELE)

تصاعد: معيار السكك الحديدية DIN, عرض 36 مم (2 وحدات)

المعايير: غيغابايت 16916 / IEC 61008‑1

Built-in test button. Must be fitted with an upstream MCB for short-circuit and overload protection (RCCB itself does not protect against short-circuit or overload faults).

Key Distinction

RCCB: Earth leakage protection only; always requires an upstream miniature circuit breaker.

EZ7RCBO: Combined earth leakage + الزائد + حماية ماس كهربائى (integrated RCBO). Do not mix these two types.

Replacement Selections (إبداعي شنايدر alternatives)

1. Economy direct replacement: Easy9 RCCB (EZ9R series), 2P 63A 30mA Type A
2. High-end model: Acti9 iID (A9R series), 2P 63A 30mA Type A (النوع الكهرومغناطيسي, better anti-interference)
3. Integrated all-in-one option (RCBO): Easy9 RCBO / iC65N Vigi add-on residual current block

ملاحظات إضافية

The entire EZ7 range (including EZ7RCCB and EZ7Vigi add-on leakage blocks) was officially discontinued by Schneider on 30 June 2023. No further production runs will be made; stock on the market is leftover inventory. For new projects and long-term maintenance, switch directly to the Easy9 series to avoid future supply shortages.

Application Scope for EZ7RCCB‑63A (2ص, 30أماه, النوع أ, Electronic RCCB)

شرط مسبق: Only earth leakage protection; no overload/short-circuit protection. An upstream MCB is mandatory. Type A detects AC + تسرب العاصمة النابض; 63A is the continuous current rating, not the fault trip current.

✅ Recommended Applications

1. Main household residual current protection (single-phase 220V incoming supply)

Main incoming earth leakage protection for residential apartments and homes, with multiple downstream MCBs. Ideal for circuits with inverter air conditioners, variable-frequency washing machines and switch-mode power supply appliances (advantage of Type A). Centralised protection for wet-area circuits (حمام, balcony, kitchen socket circuits).

2. Single-phase main protection for small shops, convenience stores and retail premises

Mixed lighting + socket circuits with many PCs, سجلات النقد, LED drivers and variable-frequency equipment. Used in low-cost distribution boxes for ground-floor commercial premises to provide collective earth leakage protection.

3. Branch main RCD for small offices and computer rooms

Large numbers of adapters, يو بي إس, computers and switch-mode power supplies. AC-type RCCBs are prone to nuisance tripping, so Type A is preferred for collective protection of a group of socket circuits.

4. Small single-phase commercial equipment control panels

Commercial water purifiers, heat pumps, variable-frequency water heaters and small automation control cabinets. Earth leakage protection for metal-cased equipment.

5. Single-phase main protection for temporary site distribution boxes (economy projects)

High risk of personnel contact with metal power tools. ملحوظة: Most construction site codes require time-delayed selective RCDs or site-specified residual current devices. This model is instantaneous 30mA, so verify local regulations before selection.

⚠️ Conditional Applications (with restrictions)

Single-phase AC side of small PV systems: Only for the AC side. Type A cannot be used on the DC side; DC-side protection requires Type B. The AC output of inverters contains pulsating DC components, which Type A can handle properly.

شحن السيارة الكهربائية: Not recommended for standard AC slow chargers. Current national standards require Type B residual current protection for charging circuits.

❌ Not Suitable for These Scenarios

1. Cannot be used standalone without an upstream MCB; without short-circuit/overload protection, cables will burn out under fault conditions.
2. Pure resistive loads with no electronic equipment: AC-type RCCBs are cheaper; Type A is unnecessary.
3. Medical Class 1 locations, swimming pools and fountains: Normally require 10mA high-sensitivity RCDs or Type B / specialised selective residual current devices.
4. Three-phase circuits: This is a 2P single-phase device; not for three-phase applications.
5. Selective graded protection (to avoid cascading tripping): This is instantaneous with no time delay. Upstream and downstream 30mA RCDs will trip simultaneously.
6. Heavy industrial variable-frequency sites with severe harmonic interference: Electronic RCCBs suffer frequent nuisance tripping. Use electromagnetic iID models instead.

📌 Selection Summary (EZ7 discontinued; new projects use EZ9R 2P 63A Type A 30mA directly)

تحديد المواقع: Economy Type A main RCD for collective earth leakage protection of multiple circuits, especially circuits with large numbers of switch-mode power supplies and variable-frequency single-phase loads.

Typical circuit topology: Incoming supply → MCB (ماس كهربائى + الزائد) → EZ7RCCB → multiple branch circuits.

Supplementary Selection Rules

1. RCCBs cannot be used without an upstream MCB; RCBOs can be used on individual final circuits without extra breakers.
2. EV chargers, DC circuits and heavy variable-frequency drives require Type B; circuits with switch-mode power supplies and inverters use Type A; pure resistive lighting can use cheaper AC type.
3. SI selective models are used on main feeders to prevent simultaneous tripping of upstream and downstream residual current devices.
