About Bel Circuit Protection
About Bel Circuit Protection
Bel Fuse was founded in 1949 by Elliot Bernstein in Jersey City, New Jersey, originally to manufacture fuses for the booming postwar automobile market. The company soon expanded into fuses for another fast-growing consumer product category, televisions, riding the wave of mid-century American manufacturing growth.
A collaboration with RCA Corp produced the first delay lines used in color television sets, and as the computer industry took off through the 1970s and 1980s, Bel Fuse moved with it, counting IBM and Digital Equipment Corp among its customers while expanding into miniature fuses. By 1983 the company had grown past $18 million in revenue with manufacturing operations in Hong Kong and Macao.
Bel Circuit Protection is now part of the broader Bel Fuse portfolio, which spans circuit protection, magnetics, power solutions, and interconnect products built into other companies' equipment. On ChatMRO, engineers can describe the voltage, current rating, or form factor they need to find the matching Bel fuse or protection component.
