MCB, RCCB, RCBO or MCCB: Which Do You Need?
| Device | Protects against | Typical use |
|---|---|---|
| MCB | Overload and short circuit | Final circuits and control circuits, usually up to 125 A |
| RCCB | Earth leakage only | Shock and fire protection, used with an MCB upstream or downstream |
| RCBO | Overload, short circuit and earth leakage | Individual circuits that need both functions in one device |
| MCCB | Overload and short circuit, often with adjustable settings | Incomers and large feeders at higher currents |
| ACB | Overload, short circuit and other protection functions | Main incomers on large distribution boards |
An RCCB has no overcurrent protection of its own, so it must always be paired with a suitable MCB or fuse. For MCBs, choose the trip curve to suit the load: curve B for resistive loads and lighting, curve C for general and motor-type loads, and curve D for loads with high inrush such as transformers.
How to Specify Switchgear for a Quote
Switchgear must suit the circuit it protects, so a part number alone is not always enough when you are designing a new panel. Include these details:
- Rated current and number of poles for breakers and isolators.
- Breaking capacity in kA, which must equal or exceed the prospective fault current at that point.
- Trip curve for MCBs, and sensitivity in mA and type for RCCBs and RCBOs.
- Coil voltage and utilisation category for contactors, for example AC-3 rating for motor switching.
- Setting range for thermal overload relays, matched to the motor full-load current.
- Output voltage and wattage for power supplies, with some margin above the load.
For a full panel, send the bill of materials or single-line diagram. We will quote all CNC Electric items together and point out any lines that need clarification.

Buyer questions
Frequently Asked Questions
What is CNC Electric?
CNC Electric is a manufacturer of low-voltage electrical products, including the YC-series switchgear. EKA CNC supplies its range across nine categories, from DIN-rail MCBs and RCBOs to MCCBs, air circuit breakers, contactors, relays, power supplies and energy meters. The brand name describes the products; it is not the same company as EKA CNC.
Can I get all the switchgear for a control panel in one quote?
Yes. Send your bill of materials or single-line diagram with quantities, and we will quote all CNC Electric items together. Where a line is unclear, such as a missing breaking capacity or coil voltage, we will ask before quoting so the parts match your design.
Which MCB trip curve should I choose?
Curve B trips at lower inrush and suits resistive loads and lighting. Curve C is the general-purpose choice for mixed loads, small motors and control circuits. Curve D tolerates high inrush from transformers and some motors. Choose the curve that avoids nuisance tripping while still protecting the cable.
How do I size a contactor and thermal overload relay for a motor?
Select a contactor whose AC-3 rating is equal to or above the motor's full-load current at your supply voltage, with the correct coil voltage. Then choose a thermal overload relay whose setting range includes the motor full-load current, and set it to that value. Send the motor nameplate if you want us to check the selection.
Can CNC Electric parts replace other brands in my existing panel?
Often, yes, as long as the rating, poles, breaking capacity and coil voltage match and the part fits the available space and mounting. DIN-rail devices are usually straightforward. Contactors, MCCBs and relays with bases or accessories need dimensions and auxiliary contacts checked. Send the existing part numbers and we will suggest equivalents.
Do you supply machine tool control transformers and power supplies?
Yes. The power equipment range includes JBK and BK series machine tool control transformers and switch-mode power supplies in many wattages. Tell us the input and output voltages and the VA or wattage needed. Our guide to control transformers explains how they are used.
What maintenance does panel switchgear need?
During planned shutdowns, check terminal tightness, look for discolouration from heat, clean dust from the panel, test RCCBs and RCBOs with their test button, and check contactor contacts for wear. Replace devices that show burning or that trip without cause.
How do I get price and availability?
Send the model numbers or your bill of materials, with quantities and delivery location, through the quote request form, by email to contact@ekacnc.com or by phone. We will confirm price and availability for each item and ship across India.
