6️⃣ How to Use 

Follow these steps to install your TOMZN TOB1-63H4P AC MCB C Type 230/400V~ 50HZ/60HZ 63A Mini Circuit Breaker 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 or neutral. 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 DIN rail. Hook the bottom clip of the TOMZN 4P MCB onto the rail. Push the top section firmly until you hear a click.

Step 3: Connect Incoming Wires
Identify the incoming L1, L2, L3 (phases) and Neutral wires. Connect each to the top terminals marked 1, 3, 5, and N (or 1, 2, 3, N). Tighten all terminal screws securely.

Step 4: Connect Outgoing Wires
Take the outgoing wires running to your load. Connect L1, L2, L3, and Neutral to the bottom terminals (2, 4, 6, and N). Double-check each connection for tightness.

Step 5: 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 6: Label the Circuit
Write the equipment or area name on your distribution board label. Note that this 4-pole breaker controls all three phases and neutral.

Safety Tips

• Use 16mm² or larger copper wire for 63A circuits.

• Never operate the breaker without the cover installed.

• Keep the breaker dry and free from dust.

Maintenance Guidance
Test each pole 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 4-pole breaker immediately.

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