Obsolete Square D & Schneider Electric Breakers
Obsolete Square D & Schneider Electric breakers function perfectly fine, contrary to popular belief. In fact, they are merely parts at the end of the product life cycle.
Newer models may have replaced them, but many electricians use obsolete parts to repair or restore something that works exceptionally well, rather than replace it with a newer model.
About Schneider Electric
Schneider Electric began in 1902 in Detroit as the Detroit Fuse and Manufacturing Company. The company made a name for itself building enclosed fuses and fuse switches. Today, it is a multinational conglomerate specializing in energy management and automation.
Schneider Electric is also another name for Square D products. The company changed its name to Square D in 1917. The move was strategic as it capitalized on its well-known trademark logo, which was a capital letter D inside a square, found on all Square D circuit breakers.
Obsolete Electrical Breakers
Schneider Electric circuit breakers are one of the most popular obsolete circuit breakers on the market. Electrical circuit manufacturers like Square D are continually improving their circuit breaker technology. As a result, sometimes electrical engineers need to use obsolete circuit breakers for repairs, because this is more advantageous than upgrading the entire panel.
Buying Replacement Options
Buying certified used circuit breakers could allow you to save up to 70%, when compared to buying a new model. But before you decide on anything, make sure to check the distributor’s open-market sourcing ability and experience. The original manufacturers can refer you to their trusted distributors so you can trace exactly where their old products have gone.
The distributor should also possess a rigorous testing program for any used components. This guarantees authenticity and the general lifespan of the used product.
Below you will find more information on available replacement options for obsolete Square D and Schneider Electric breakers, all taken from our Square D breakers catalog.
EDB24020 Miniature Circuit Breaker
The EDB24020 is a miniature circuit breaker made by Schneider Electric. It has a Square D branch type of EDB. This circuit breaker also has two poles, meaning it can protect two independent circuits at the same time.
It has an amperage rating of 20 A and voltage rating of 480 V. It is a molded case thermal magnetic circuit breaker, so it is enclosed inside a case and consists of a bimetal strip and an electromagnet as its tripping mechanisms.
EDB34050 Miniature Circuit Breaker
The EDB34050 is a miniature circuit breaker made by Schneider Electric. Similar to the EDB24020, it has a branch type of EDB. It has three poles, allowing the circuit breaker to protect three independent circuits at the same time.
The amperage rating on the EDB34050 is 50 A, and its voltage rating is 480 V. It also has a high trip setting, starting from 630 amperes to 1800 amperes. It is a molded case thermal magnetic circuit breaker, so it is enclosed inside a case and with a bimetal strip and an electromagnet.
EHB14030 Molded Case Circuit Breaker
The EHB14030 by Square D is a molded case circuit breaker. They are designed with an electrochemical trip unit that protects against excess current. The inner design of the EHB14030 consists of two devices, one that detects changes in temperature and another that detects changes in currents.
Unlike other Square D circuit breakers mentioned above, the EHB14030 only has one pole, so it can only protect a single circuit at a time from excess currents. It also has a low amperage rating of 30A and a voltage rating of 277V.
EHB34060 Molded Case Circuit Breaker
The EHB34060 is another molded case circuit breaker by Square D. It is made up of a device that detects changes in temperature and another device that detects changes in currents.
It has a slightly higher amperage rating of 60 A. Its voltage rating is also higher at 480V, with three poles to protect three circuits at the same time.
CM1250H Insulated Case Circuit Breaker
The CM1250H insulated case circuit breaker by Square D is different from regular molded case circuit breakers. They have an extra 2-step stored energy mechanism and function like an iron-frame circuit breaker without the iron frame.
The amperage rating on the CM1250H is 600 A, while its voltage rating is 1250 V. It also has three poles, so it is capable of protecting three independent circuits.
Obsolete electrical circuit breaker products go through testing and go back to market as used or obsolete electrical parts. Electric circuit breakers are one of the most popular items on the obsolete electrical components list, and Square D/Schneider Electric is a large manufacturer of these parts. Popular circuit breakers include the EDB34050 miniature circuit breaker and the EHB34060.
