EHB3020L - 20Amp Circuit Breaker

EHB3020L - 20Amp Circuit Breaker

When you're maintaining an existing electrical system, finding the right replacement breaker is about more than matching the amperage. The EHB3020L is a 3-pole, 20-amp Type EHB thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible panelboards manufactured before 1989. If your existing equipment was originally built to use this breaker style, matching the correct type, dimensions, interrupting rating, and terminal configuration helps keep the system operating as it was designed.

This breaker features a non-interchangeable thermal-magnetic trip unit that combines overload and short-circuit protection in a single device.

Where It Works Best

The EHB3020L is a practical choice for maintaining compatible electrical systems found in commercial buildings, manufacturing facilities, schools, healthcare facilities, office buildings, warehouses, and other industrial environments. It is intended for panelboards manufactured before 1989 that require a Type EHB 3-pole, 20-amp circuit breaker with matching electrical ratings and physical dimensions. When maintaining legacy equipment, using the correct replacement breaker helps preserve the original system design and supports reliable operation.
