Specification of Miniature Circuit Breaker MCB ABB Standard SPLN 108 / SLI 175
Definition MCB / Circuit Breaker
MCB (Miniature Circuit Breaker) is a Circuit Breakers Electrical Equipment On An Electric Power System, Able To Opening And Closing of Electric Circuits Under All Conditions, Including short-circuit currents, In accordance with the rating. Also On The Voltage Condition Normal Or Not Normal.
Miniature Circuit Breaker (MCB) In Design With Main Function To:
Securing Cables Charges Against More And Short-circuit currents.
Skipping Over Flow Without heating.
Opens And Closes A circuit Under Flow Identifier.
Selection of Miniature Circuit Breaker (MCB)
Selection Circuit Power Determined By A Few Things:
1. Standard
- SPIN 108 / Sli 175, When Used By Public User (Installation Housing - Low Capacity Termination).
- Iec 60947-2, When Used By Expert (Industrial Applications - High Capacity Termination)
2. Capacity Termination
Capacity Termination A Must breaker Power Greater Than Short-circuit currents On Point Installation Everywhere Such Installed power breakers. On Line Chart A System, is recommended to also mention Large Flow Capacity Termination Alongside Used Power Circuit Identifier.
3. Flow Identifier
Flow Power Circuit Identifier Should Be Tailored To The magnitude of currents Expenses Skipped Over Cable And Small Of Permitted Flow On Cable.
4. Tension
Operating Voltage Power Circuit Identifier Must Greater Or Equal To Voltage Systems.
5. Number of Pole
6. Shape Trip curve (curve C or curve D)
Great Trip To determine Magnetic Flow Identifier.
7. Frequency Systems
8. Load Applications
The Cable Type secured, copper or aluminum.
MCB (Miniature Circuit Breaker) Available From Single Phase, Phase Two, Phase Three. Merk Shneider, Merlin Gerin, Abb, Hager, Legrand, Etc. MCB (Miniature Circuit Breaker) Can be Found In Our Company.
