EHB1020 - 20Amp Circuit Breaker

EHB1020 - 20Amp Circuit Breaker

When you need to replace a compatible breaker in an existing electrical system, getting the right fit matters. The EHB1020 is a 1-pole, 20 Amp thermal-magnetic molded-case circuit breaker designed as a form, fit, and function replacement for compatible EHB series installations. Specifically intended for use in electrical panels manufactured before 1989, it helps keep existing systems operating as originally designed without requiring modifications to compatible equipment.

Inside the breaker, the thermal-magnetic trip mechanism provides protection against both prolonged overloads and short-circuit conditions. Its non-interchangeable trip unit preserves the breaker's original configuration, while the 14kA interrupting rating at 277VAC makes it suitable for applications requiring that level of fault protection. Because load terminals are included, installation is more convenient when replacing an existing compatible unit.

Where It Works Best

The EHB1020 is commonly found in commercial, industrial, and institutional electrical systems, where compatible EHB series breakers are still used. It's a practical replacement for lighting panels, distribution equipment, branch circuits, and other legacy electrical installations that require a 1-pole, 20 Amp thermal-magnetic circuit breaker with a 14 kA interrupting rating at 277 VAC.
