63 Amp RCCB
Compare types, poles and sensitivities.
Shortlist VIOX 63A residual current circuit breakers in 2P and 4P configurations. Compare the published series, then build a specification for a project or wholesale quotation.
Start with the right 63A series.
All four catalogs list 63A. Choose the residual-current type from the connected equipment and project requirements, not from the current rating alone.
VKL11
Type AC / A / ASi
AC, pulsating DC or high-immunity Type A requirements. The 10mA option is not listed at 63A.
VKL11F
Type F
Mixed-frequency residual currents associated with specified single-phase electronic loads.
VKL11B
Type B / B+
Smooth-DC residual-current detection. Select Type B or B+ and verify the time characteristic.
VKL11-EV
Type A EV / F EV
A-EV or F-EV for the declared EV charging arrangement. F-EV is listed at 30mA only.

The table summarizes published catalog options. It is not a stock list or a guarantee that every combination is available. Confirm the exact type, poles, sensitivity and time characteristic before ordering.
| Series | Residual-current type | IΔn options at 63A | Poles / rated voltage | Selection boundary |
|---|---|---|---|---|
| VKL11 | AC / A / ASi | 30, 100, 300mA | 2P: 240V AC 4P: 415V AC | 10mA is limited to 16–40A. ASi has a different time characteristic from the instantaneous variants. |
| VKL11F | F | 30, 100, 300mA | 2P: 230/240V AC 4P: 400/415V AC | Mixed-frequency detection; short-time delayed. Confirm equipment-specific requirements. |
| VKL11B | B / B+ | B: 30, 100, 300, 500mA B+: 30, 100, 300mA | 2P: 230/240V AC 4P: 400/415V AC | Selective versions do not list 30mA. B+ documentation must match the exact variant. |
| VKL11-EV | A-EV / F-EV | A-EV: 30, 100, 300mA F-EV: 30mA | 2P: 240V AC 4P: 415V AC | Catalog specifies integrated smooth-DC detection with a maximum 6mA switch-off threshold. Verify the charging-system protection arrangement. |

63 amp 2 pole or 4 pole RCCB?
2P: single-phase circuits
A 2-pole RCCB typically switches the phase and neutral together. Confirm the circuit voltage and the device’s test-circuit requirements. VKL11 and EV catalogs list 240V AC; F and B catalogs list 230/240V AC.
4P: three-phase and neutral
A 4-pole RCCB typically serves three phases plus neutral. The published ratings are 415V AC for VKL11/EV and 400/415V AC for F/B. A circuit without neutral needs model-specific wiring and test-circuit verification.
See the RCCB wiring referenceChoose 30mA, 100mA or 300mA separately.
- 30mA
- Commonly used for additional electric-shock protection where required. It does not replace earthing, basic protection or correct circuit design.
- 100mA
- May be specified for fault protection with a coordinated earthing system and disconnection design. Not a substitute for required 30mA additional protection.
- 300mA
- May be used for insulation-fault fire-risk reduction or upstream protection where the installation design permits. Selectivity also requires time coordination, not just a higher mA rating.
Match the waveform. Then check coordination.
Type AC covers sinusoidal AC residual currents. Type A adds pulsating DC. Type F addresses specified mixed-frequency residual currents; Type B adds smooth-DC detection. These are not interchangeable labels for “better quality.”
For EV charging, verify the equipment’s required AC residual protection and DC detection arrangement. An A-EV or F-EV variant must not simply be described as Type B.
Compare RCCB residual-current typesWhat your protection designer must verify
- Load current, ambient conditions and any required derating against the 63A rating.
- The upstream MCB or fuse, its rating and the manufacturer’s coordination conditions.
- Prospective short-circuit current against the RCCB’s conditional ratings with the specified protective device.
- Residual making/breaking capacity IΔm separately from conditional short-circuit ratings Inc / IΔc.
- Earthing, disconnection times and selectivity with other RCDs.
IEC 61008-1 covers RCCBs without integral overcurrent protection. A conditional 6kA or 10kA catalog rating does not mean the RCCB independently clears that fault like an MCB.
63 amp RCCB price: compare the same specification.
A useful price comparison starts with poles, type, sensitivity and required documentation. A 63A 2P Type A device and a 63A 4P Type B device are different purchasing requirements.
Ask for a quote that identifies the exact series and configuration, quantity, packaging, sample requirements and delivery terms. This page does not publish an unverified fixed price.
For buyers sourcing to India
Separate local branded retail prices from an OEM or wholesale supply quotation. Specify your delivery destination, currency, freight and tax basis, and the conformity documents your project or import process requires.
Do not assume a listed IEC standard alone establishes Indian market acceptance. Confirm the exact order’s documentation before purchase; local inventory, landed cost and delivery timing must be quoted, not inferred.
