EH3B050 - 50Amp Circuit Breaker

EH3B050 - 50 Amp Circuit Breaker

When you’re maintaining an existing electrical system, finding the right breaker isn’t just about specs—it’s about getting a part that fits correctly and performs the job it was designed for. The EH3B050 molded case circuit breaker is built with that exact purpose in mind. With a 50-amp rating and 3-pole configuration, it provides dependable overcurrent protection for three-phase systems while matching the EH3 frame requirements found in many established installations. This breaker is designed to handle real-world electrical demands with interrupting ratings of 14k A.I.C. at 480VAC and 18k A.I.C. at 240VAC. That means it’s ready to safely interrupt fault conditions and help protect your equipment from damage. Its molded case construction helps shield internal components from dust, debris, and everyday wear, making it a solid choice for environments where consistency matters. If you’re working with an existing panel or switchboard that calls for an EH3 frame, this unit offers a straightforward, no-hassle fit that keeps your system operating as intended.
