Answer: It protects three-phase circuits including motors, compressors, pumps, and main distribution panels. The breaker disconnects all three poles simultaneously.

Q2: Can I install the CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan myself?
Answer: Only a licensed industrial electrician should install three-phase breakers. The DIN rail design makes professional installation straightforward.

Q3: Why choose a 3-pole breaker instead of three 1-pole breakers for my CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan?
Answer: A 3-pole breaker features a common trip mechanism. When one phase faults, all three poles open together, preventing single-phasing damage to motors.

Q4: Does the CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan work with single-phase systems?
Answer: No, this 3-pole breaker is designed specifically for three-phase systems. For single-phase, use a 1-pole or 2-pole CHINT breaker.

Q5: How do I reset the CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan after a trip?
Answer: Move all three levers fully to the OFF position, then push them back to ON together. The breaker resets when you clear the fault.

Q6: What does "C Type" mean on the CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan?
Answer: C Type indicates the tripping curve. It tolerates motor starting surges (5-10 times rated current) without nuisance tripping.

Q7: Does the CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan require a neutral connection?
Answer: No, a 3-pole breaker connects only to the three phase wires. The neutral wire connects directly to the neutral bus bar separately.

6️⃣ How to Use 

Follow these steps to install your CHINT AC Breaker 3 Pole NXB-63C MCB in Pakistan correctly. Always prioritize safety.

Step 1: Turn Off Main Power
Switch off and lock out the upstream main breaker. Use a voltage tester to confirm no electricity flows on any phase. Never work on live three-phase systems.

Step 2: Prepare the Distribution Board
Open your three-phase distribution board cover. Locate a free slot on the 35mm metal DIN rail. Hook the bottom clip of the CHINT 3P MCB onto the rail. Push the top section firmly until you hear a click.

Step 3: Connect Incoming Wires
Identify the incoming L1, L2, and L3 (phase wires - usually red, yellow, blue). Connect each to the top terminals marked 1, 3, and 5 (or L1, L2, L3). Tighten all terminal screws securely.

Step 4: Connect Outgoing Wires
Take the outgoing phase wires running to your three-phase load (motor, compressor, or sub-panel). Connect L1, L2, and L3 to the bottom terminals marked 2, 4, and 6. Double-check each connection for tightness.

Step 5: Connect Neutral (If Required)
A 3-pole breaker does not connect to neutral. If your load requires a neutral, connect it directly to the neutral bus bar, not through this breaker.

Step 6: Verify Phase Rotation
Before connecting sensitive equipment, verify correct phase sequence (L1, L2, L3) using a phase rotation meter. Incorrect sequence damages three-phase motors.

Step 7: Label the Circuit
Write the equipment or area name on your distribution board label. Note that this 3-pole breaker controls all three phases.

Safety Tips

• Use 10mm² or 16mm² copper wire for 63A three-phase circuits.

• Never operate the breaker without the cover installed.

• Keep the breaker dry and free from dust.

Maintenance Guidance
Test all three poles every six months. Toggle all levers together to ensure smooth operation. Check all terminal screws annually using a torque screwdriver. If you notice burning smells or discoloration on any pole, replace the entire 3-pole breaker immediately.

Restoring Power After a Trip
When the breaker trips, first inspect all connected equipment for faults. Move all three levers fully to OFF, then push them back to ON together. If it trips again, call an industrial electrician immediately.
