Frequently Asked Questions - MCB-100 ENTES

What does MCB stand for?

MCB stands for Miniature Circuit Breaker, a device that automatically switches off electrical circuits during overload or short circuit conditions.

What is the rated current of the ENTES MCB-100?

The rated current (In) is 100 A, suitable for high-power loads.

What tripping curve does this MCB have?

It has a Type C tripping curve, designed for moderate inrush currents (e.g., motors, transformers).

Can I use this MCB for DC circuits?

No, this MCB is rated for AC circuits only (230/400 V AC). It is not suitable for DC applications.

How do I install the MCB-100?

Install on a 35 mm DIN rail by snapping it into place. Connect the line and load wires to the terminals using appropriate torque. Ensure power is off during installation.

What is the breaking capacity?

The breaking capacity is 10 kA per IEC 60898-1, meaning it can safely interrupt fault currents up to 10,000 A.

How do I know if the MCB has tripped?

The switch handle will move to the OFF (down) position. To reset, first remove the cause of the fault, then push the handle back to ON (up).

Is this MCB suitable for residential use?

Yes, it is commonly used in residential, commercial, and light industrial distribution boards for branch circuit protection.

Does it require any maintenance?

Minimal maintenance is needed. Periodically check for signs of damage or overheating. Keep clean and dry. Do not open the device.

What should I do if the MCB fails to reset?

If it cannot reset, there may be a persistent fault. Consult a qualified electrician to inspect the circuit. Do not attempt to bypass or repair the MCB.
