EHB2090L - 90Amp Circuit Breaker

EHB2090L - 90Amp Circuit Breaker

Finding the right replacement circuit breaker is about more than matching the amperage. It also means choosing a breaker that fits your existing equipment and maintains your system's original electrical design. The EHB2090L is a 2-pole, 90 Amp Type EHB thermal-magnetic circuit breaker designed specifically as a form, fit, and functional replacement for compatible Type EHB panelboards manufactured before 1989. Its thermal-magnetic trip mechanism helps protect electrical systems by responding to both sustained overloads and short-circuit conditions, making it a dependable choice for maintaining existing commercial and industrial installations.

Built to last and engineered for legacy electrical systems, the EHB2090L helps keep existing panels operating as originally designed. Before installation, always verify the breaker type, amperage, voltage, interrupting rating, and panel compatibility to ensure it matches your specific application.
