• Tripping characteristics (B, C, or D curves) based on inrush current and load behavior

• Short-circuit capacity suitable for the reduced fault levels present at downstream locations

Practical Limitations fro Lauritz Knudsen MCB in Industrial Systems

While MCBs are reliable and cost-effective for low-fault applications, they are not intended for primary protection in high short-circuit zones. In industrial systems, MCBs are typically installed downstream of MCCBs or ACBs, where fault levels have already been limited through upstream protection.

Molded Case Circuit Breakers (MCCBs)

Role in Industrial Protection Systems

Molded Case Circuit Breakers (MCCBs) form the primary protection layer in most industrial electrical installations. Lauritz Knudsen MCCBs are widely specified for:

• Main incomer and feeder protection

• Motor feeders and industrial distribution panels

• Electrical loads exposed to moderate to high fault levels

• 
  

In industrial power systems, MCCBs typically operate between upstream ACBs and downstream MCBs, serving as a critical link in the protection hierarchy.

Key Selection Parameters for Lauritz Knudsen MCCB in Industrial Applications

Selection of MCCBs should be based on:

• Rated current with adequate margin for continuous operation and future load growth

• Breaking capacity aligned with calculated prospective short-circuit current at the installation point

• Adjustable thermal and magnetic trip settings to match load characteristics

• Coordination and selectivity with upstream ACBs and downstream MCBs to ensure controlled fault isolation

• Proper evaluation of these parameters is essential for maintaining system reliability and minimizing unnecessary shutdowns.

Why Lauritz Knudsen MCCBs Are Preferred Over MCBs in Industrial Systems

MCCBs offer significantly higher breaking capacities, adjustable protection settings, and improved coordination flexibility compared to MCBs. These characteristics make them suitable for industrial environments where load variation, higher fault energy, and operational continuity must be carefully managed.

Correct MCCB selection helps prevent nuisance tripping during normal operation while ensuring reliable and selective fault clearance under abnormal conditions, protecting both equipment and personnel.

Air Circuit Breakers (ACBs)

Typical Industrial Applications

Lauritz Knudsen Air Circuit Breakers (ACBs) are used in high-current, high-duty applications where system reliability and maintainability are critical. Typical applications include:

• Main incomer panels for large industrial and commercial facilities

• Generator and transformer protection

• Large industrial switchboards and substations

In industrial power distribution systems, ACBs are generally installed at the top of the low-voltage protection hierarchy, serving as the primary incoming protection device.

Key Selection Parameters for Lauritz Knudsen ACBs in Industrial Use

Critical selection factors include:

• Short-time withstand capacity to safely handle high fault currents

• Mechanical and electrical endurance suitable for frequent switching operations

• Coordination and selectivity with downstream MCCBs to ensure controlled fault isolation

• Ease of maintenance, accessibility, and serviceability in critical installations

  
  

These parameters directly influence system uptime and operational continuity.

When Lauritz Knudsen ACBs Are Preferred Over MCCBs

ACBs are typically selected when fault currents, switching frequency, or system criticality exceed the practical limits of MCCBs. Their ability to withstand high short-time currents, support adjustable time delays, and facilitate selective coordination makes them suitable for main incomer and critical distribution points.

In applications where uninterrupted operation and fast service restoration are essential, ACBs provide a level of robustness and flexibility that MCCBs cannot practically offer.

Switchgear and Distribution Boards

Role in Industrial Power Distribution

Lauritz Knudsen Switchgear and distribution boards form the structural and functional backbone of industrial power distribution systems. They integrate protection devices, control equipment, and monitoring components into a coordinated and safe assembly.

Lauritz Knudsen switchgear solutions are commonly specified for:

• Power distribution panels

• Motor control centers (MCC panels)

• Industrial substations and utility interfacing panels

In industrial installations, switchgear provides the physical framework that enables proper protection coordination, safe power distribution, and operational control.

Key Considerations for Panel Builders and Consultants

Specification decisions are influenced by several technical and operational factors, including:

• Compatibility with protection devices such as ACBs, MCCBs, and MCBs, as well as associated control gear

• Panel layout, space constraints, busbar rating, and thermal management requirements

• Degree of segregation, safety clearances, and accessibility for maintenance activities

• Ease of installation, operation, and routine servicing

• Provision for future expansion, system upgrades, and load growth

In industrial environments, switchgear selection extends beyond component ratings. It directly affects fault containment, operator safety, ease of maintenance, and long-term system flexibility.

How to Choose the Right Lauritz Knudsen Electrical Products for Industrial Applications

Selecting electrical products for industrial projects requires a disciplined evaluation of electrical, environmental, and operational parameters.
