Switchgears play a critical role in managing electrical systems—controlling, isolating, and protecting electrical circuits in both industrial and commercial environments. However, when they fail, the results can be severe—power outages, safety hazards, equipment damage, and costly downtime.
Understanding the common failures associated with low voltage switchgear, their causes, and most importantly, how to prevent them, is essential to maintaining an efficient and safe electrical infrastructure.
In this blog, we’ll walk you through:
- The most frequent switchgear failures
- Practical steps for prevention
- Expert advice to help you make informed decisions
- A way to get a free consultation to optimize your current setup
What Are the Common Switchgear Failures?
- Insulation Breakdown
Over time, the insulating material within switchgears degrades due to heat, moisture, and contamination. This breakdown can lead to short circuits and arc faults. - Mechanical Wear and Tear
Frequent operations can wear out moving parts like contacts, springs, and levers. Inadequate maintenance worsens the issue, leading to inconsistent performance or outright failure. - Corrosion and Contamination
Especially in industrial or humid environments, moisture or dust can corrode components of low voltage switchgear, resulting in overheating and operational faults. - Faulty Installation or Loose Connections
Incorrect wiring or loose terminal connections are a leading cause of overheating and failure. They not only reduce efficiency but also pose serious safety hazards. - Overloading and Underrating
Using low voltage switchgear not rated for the actual load it has to bear can result in overheating and system damage over time.
How to Prevent These Failures
- Regular Preventive Maintenance
Conduct thermal imaging, insulation testing, and visual inspections regularly. Maintenance schedules should be a part of your operational checklist. - Environment Monitoring
Install switchgears in dust-free, moisture-controlled environments. Use enclosures with IP ratings suitable for your application. - Load Analysis and Proper Sizing
Ensure you’re not overloading your system. Work with experts to choose the correct switchgears that can handle your load comfortably. - Trained Installation and Testing
Work with professionals who follow best practices in installation. Poorly connected systems are more prone to failure. - Upgrade Aging Systems
Many facilities continue using low voltage switchgear that’s well past its recommended life. Upgrading reduces the risk of downtime and improves safety.
Here’s Where Most Consumers Go Wrong
A common mistake is waiting for a failure before reacting. Proactive management—especially with complex electrical systems—is key. Unfortunately, not all companies have the in-house expertise to identify early signs of trouble or choose the right switchgears for the job.
