Frequently Asked Questions - CBCT-38 ENTES
What is the primary function of the ENTES CBCT-38?
The ENTES CBCT-38 is a core balance current transformer used to detect residual currents in electrical installations. It senses leakage current to ground and sends a signal to a protection relay for earth leakage protection.
How do I install the CBCT-38 correctly?
Pass the cable carrying the load current through the central hole (38 mm diameter) of the transformer. Ensure that the cable passes centrally and that all phase conductors and the neutral (if required) are passed together. Secure the transformer using the fixing bracket.
What is the meaning of the inner diameter 38 mm?
The 38 mm inner diameter indicates the maximum cable width that can pass through the transformer. The CBCT-38 is suitable for cables up to 38 mm outside diameter.
Can the CBCT-38 measure DC residual currents?
No, the CBCT-38 is designed for AC residual current detection at 50/60 Hz. For DC leakage detection, a different type of sensor is required.
Which ENTES protection relays is the CBCT-38 compatible with?
The CBCT-38 works with ENTES EPR series earth leakage protection relays. Always verify the relay's secondary coil requirement to ensure a proper match.
How do I test the CBCT-38 during commissioning?
Use a test mechanism on the connected relay to simulate a residual current, or apply a small AC current through the center and measure the secondary output. Ensure the signal matches the expected transformation ratio.
What maintenance is required for the CBCT-38?
No regular maintenance is needed. Inspect the transformer periodically for dust accumulation, physical damage, or loose mounting. Keep the surface clean and dry to ensure reliable operation.
Can the CBCT-38 be used for overload protection?
No, the CBCT-38 is specifically for residual current (earth leakage) detection. It is not intended to measure load currents for overload protection.
What is the maximum cable diameter accepted?
The CBCT-38 accepts cables up to 38 mm outer diameter. If your cable is larger, consider a larger core balance transformer model.
Is the CBCT-38 safe to install in wet environments?
The device has an IP20 rating, meaning it is protected against particles larger than 12 mm but not moisture. Install it in a dry, clean indoor environment within the specified temperature range.
