EHB2020L - 20Amp Circuit Breaker

EHB2020L - 20 Amp Circuit Breaker

If you’re working with an older electrical panel and need a breaker that simply fits and does the job right, the EHB2020L is exactly what you’re looking for. Designed specifically for panelboards manufactured before 1989, this 2-pole, 20-amp circuit breaker delivers dependable protection without the guesswork. It installs the way it should, lines up with existing components, and helps keep your system operating safely. At its core, this breaker uses a thermal-magnetic trip mechanism—meaning it reacts to both prolonged overloads and sudden short circuits. That balance is what keeps your wiring and equipment protected day in and day out. With a 14kA interrupting rating at 480VAC and a 40°C calibration, it’s built to handle typical commercial and light industrial environments where consistency matters. This is a straightforward, no-nonsense solution for maintaining the integrity of legacy systems.
