EHB2090 - 90Amp Circuit Breaker

EHB2090 - 90Amp Circuit Breaker

If you're maintaining a legacy electrical system, finding a breaker that matches the original equipment can save time and help keep your project moving. The EHB2090 is a 2-pole, 90 Amp Type EHB thermal-magnetic circuit breaker made for use in compatible Type EHB panelboards manufactured before 1989. Rather than changing your existing setup, this breaker is intended as a form, fit, and functional replacement, allowing you to maintain the original panel configuration.

Where It Works Best

The EHB2090 is commonly used in commercial, industrial, and institutional facilities where compatible Type EHB panelboards manufactured before 1989 are still in service. It's a solid choice for routine maintenance, repairs, or replacing a worn breaker while preserving the original equipment configuration. Because it's designed as a form, fit, and function replacement, it allows existing electrical systems to continue operating with the ratings and physical characteristics they were originally designed for.
