Carlos Trevino

President and Founder of CBIONE, started his career as a field salesman for the electrical wholesale industry in Southern California. During his time developing relationships with his customer base, he learned that there was a need for replacement circuit breakers for existing gear, current and obsolete. In 1980, he started CBIONE for the resale of new and reconditioned circuit breakers. This provided a solution for the immediate need for circuit breakers from various manufacturers. Carlos received his Bachelor's Degree from the University of California Los Angeles (UCLA) and extended education in Business Administration.

He performed field sales, customer development and corporate relations in the electrical wholesale industry during his first 12 years. During his time in the field, he learned that CBIONE had more capable services to offer other than the resale of new and reconditioned circuit breakers. The company had a shop service department that specialized in molded case circuit breakers for over 25 years. He spent the last 10 years working on the expansion of the shop services for low and medium voltage power circuit breakers. This addition to our product line and shop repair services has allowed CBIONE to provide more options and solutions to its customers. Ian Trevino served 4 years in the United States Navy.

We have been tasked (by one of our field service reliability testing partners) to perform circuit breaker maintenance and repair on a large line up of obsolete power circuit breakers for Los Angeles City Hall, which dates back to 1928, is the center of the government of the city of Los Angeles, California, and houses the mayor's office and the meeting chambers and offices of the Los Angeles City Council.


For the past 10 years, CBIONE and our electrical wholesale partner, have been providing circuit breakers and repair services for National Steel and Shipbuilding Company, commonly referred to as NASSCO, an American shipbuilding company with two shipyards located in San Diego, California and Norfolk, Virginia. It is a division of General Dynamics.


The weekend before Monday night NFL football between the San Diego Chargers vs the Pittsburgh Steelers on 10/12/15, Qualcomm Stadiums' main power circuit breakers was failing & needed an emergency shutdown. Our NETA certified field reliability partners were on site to access the situation and we were called upon to provide a 2000 amp power breaker that is no longer in production, yet a delay of a major national game was not an option. CBIONE was tasked to provide a solution within 24 hours. Our response to deliver was immediate.
