Browse Store When managing older industrial electrical systems, finding replacement molded case circuit breakers (MCCBs) is crucial. As key components in power distribution, MCCBs protect systems from overloads and short circuits. However, sourcing compatible replacements can be difficult when dealing with discontinued or legacy models. Here’s a comprehensive guide to locating high-quality MCCBs, ensuring your systems remain operational, safe, and compliant.
Begin with Accurate Specifications
The first step in finding a compatible replacement is documenting the breaker’s detailed specifications. Molded case circuit breakers come in a range of configurations, so you’ll want to record the following:
- Model Number and Brand: These indicate the exact type and often help suppliers match specifications.
- Voltage and Amp Rating: Ensure compatibility with the system’s power requirements.
- Trip Characteristics: Different MCCBs have specific trip functions that need to align with the system.
- Physical Dimensions: Size compatibility is essential to fit the breaker’s enclosure and maintain system integrity.
These details are critical in minimizing downtime, as accurate documentation allows for quick identification and sourcing of the correct replacement breaker and helps our sales staff ensure we get the exact breaker you need.

Explore Refurbished, Tested Options from a Trusted Supplier
While new MCCBs are ideal, they can be expensive, especially if the model is obsolete or specific to legacy systems. Used and tested MCCBs are an excellent alternative, often available at a fraction of the cost of new models while offering similar performance. Quality used units undergo a rigorous testing process to ensure they meet or exceed industry standards and may come with documented test results.
Why Choose Used and Tested MCCBs?
Refurbished MCCBs provide:
- Cost Savings: Ideal for budget-conscious operations without sacrificing quality.
- Extended Component Life: Refurbishment processes allow older equipment to perform reliably.
- Reliability and Warranty: Reputable suppliers back their refurbished MCCBs with warranties and stringent testing procedures, offering peace of mind.
