Fundamentals of circuit breaker health: new technology improves efficiency and reliability

Predicts failure so you don't have to

It’s hard to know how healthy your circuit breakers are. Which is why our breakers tell you. Our Power Defense molded case circuit breakers (MCCBs) have intuitive, convenient health monitoring features so you know when they’ll need to be replaced. That means less downtime, fewer headaches, and more productivity and peace of mind.

Determining circuit breaker health

It takes a thorough understanding of environmental conditions and electrical power system issues to know when to replace the circuit breaker. Infrared (IR) Technology is commonly used to get a better picture of breaker performance. But, IR can’t provide real-time info. Our breaker health feature gives you a true 24/7 picture so you can plan maintenance proactively, as opposed to reactively.

As the bathtub failure curb illustrates, knowing which breakers need to be replaced or services and when a breaker will fail is critical.

Power Xpert Release trip units for Power Defense molded case circuit breakers

The new frontier of intelligent power management

Our Power Xpert Release (PXR) trip units revolutionize the ability to monitor overall circuit breaker health. In fact, a smartphone with traditional safety features might be the best way to describe these new intelligent circuit breakers.

  • Temperature
  • Run-time

Embedded intelligence. Better system health.

The fundamental function of circuit breakers is evolving to support higher-level system visibility and predictive diagnostics. Advanced circuit breaker intelligence helps realize a suite of benefits.
Efficient Maintenance Model:
allows maintenance with little or no impact on critical functions
Fewer Maintenance Resources:
lowers operating costs by only performing maintenance on a system when it is required
Monitored Electricity Consumption:
enables facility and maintenance personnel to see and target inefficiencies
Simplified Regulatory Compliance:
expedites and simplifies compliance with real-time data
Rapid Outage Regulation:
identifies faults through intuitive systems for quick power restoration
New Equipment Installation:
full system capacity and capability data is readily available

Powerful analytics. Smarter decisions.

Tracking usage history and unlocking breaker data in real-time puts the power in your hands. You can plan predictive main tenance methods with precision and efficiency.

Data-driven insights will help you:

  • Increase equipment uptime
  • Reduce maintenance effort and costs
  • Boost system reliability

There are enormous system benefits that can be realized when leveraging these “smart” communicating circuit breakers and the real time information they provide.
