JC3LE-2P RCBO: 6 kA Ratings and Circuit Selection
A two-pole RCBO order can look complete while omitting the residual-current waveform and fault duty. For JC3LE-2P, those details matter more than a broad promise to prevent shocks or fires: the protective functions must match the circuit and its installation rules.
Summary: The JC3LE-2P is an RCBO: it combines overcurrent protection and 残留電流保護 in one two-pole device. Published product information describes 6-63 A choices, B or C curves, a Type A residual-current option in the current technical table and a 6 kA short-circuit rating; verify the exact order code before relying on any value. Start with circuit current, waveform, sensitivity, poles, fault level and local installation rules, then document the test-button and commissioning checks.
JC3LE-2P Protection Scope
An RCBO is selected by the protection boundary it must cover, not by the label alone. The MCB element addresses overload and short circuit; the residual-current element compares current paths and trips when the declared residual current is exceeded.
JC3LE-2P Protection Functions
The published JC3LE-2P description identifies double-pole switching, a contact indicator and selectable B/C curves. The ordered 残留電流型 must be matched to the connected load and the local code. A 30 mA, 100 mA or 300 mA sensitivity is a project decision; do not infer shock or fire protection from a generic RCBO name.
Installation boundary
Route the neutral through the sensing path specified by the wiring diagram, torque terminals to the current instructions, and verify line/load orientation. Test the device with the required instrument and record the result; a front test button does not replace the complete commissioning procedure.

RCBO Specification Checks
| 決定次元 | 確認すべきこと | なぜ重要なのか |
|---|---|---|
| Overcurrent | Rated current and B/C curve | Matches conductor ampacity and inrush |
| 残留電流 | Type AC or Type A; IΔn | Matches waveform and protection objective |
| 故障時の義務 | Declared breaking capacity | Must exceed prospective fault current |
| Switching | Two-pole neutral isolation | Supports the specified isolation method |
Reading the current JC3LE-2P listing
The current W9 product table lists 6 kA at 230/240 V, 50/60 Hz, 6–63 A options, 30/100/300 mA sensitivity and B or C overcurrent curves. Its waveform table identifies Type A. These are separate specification fields: a 6 kA short-circuit rating does not describe residual-current sensitivity, and a B curve does not make the device a Type B RCD.
An order should identify all these fields together. For example, a circuit requiring additional protection cannot adopt a higher residual-current threshold simply to stop unwanted operation. Investigate standing leakage, shared neutrals and connected equipment, then apply the destination rules and manufacturer instructions. Do not use this article as a live-work procedure.

RCBO Application Requirements
| 申請 | Check before release |

| Motor or refrigeration branch | Starting current and nuisance-trip margin |
| 電子機器用負荷 | Residual-current waveform and Type A need |
基準とコンプライアンス
IEC 61009-1 is the product standard for RCBOs; IEC 61008-1 covers RCCBs without integral overcurrent protection. IEC 60364-4-41 addresses protection against electric shock at installation level. A standard reference is not a certificate for every model, so request the exact declaration, test scope and wiring diagram for the supplied device.

よくある質問
Is JC3LE-2P a 10 kA RCBO?
The current product table lists 6 kA, not 10 kA. Use the delivered order code and marking to confirm the rating at the actual circuit voltage; do not borrow a rating from a different JC3LE model.
Does the B curve mean Type B residual-current protection?
No. B and C curves describe overcurrent operation, while Type A describes residual-current waveform capability. Both fields must be specified independently.
Can a 300 mA option replace a required 30 mA device?
Not merely to avoid tripping. Sensitivity must satisfy the circuit’s protection objective and local installation rules; a higher threshold is not an equivalent substitute for required additional protection.
Why does an RCBO trip with its load disconnected?
A shared or incorrectly routed neutral, wiring defect or device problem may remain even when the appliance is removed. A competent electrician should isolate and test the circuit rather than repeatedly reset it.
