Eaton BAB3020HS Three-Phase Miniature Circuit Breaker

The Eaton BAB3020HS is a three-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits. It is rated at 20 A and supports 120/240 V operation, with 50 Hz or 60 Hz compatibility, making it suitable for a wide range of regional power systems. This 3P device interrupts current automatically when an overload or fault occurs, helping to prevent damage to conductors and connected equipment in electrical panels. It is intended for installation in distribution boards and panelboards that require three-phase protection. The BAB3020HS designation identifies the specific model within Eaton's line of MCBs and indicates a three-pole, 20A, 120/240V, 50/60 Hz configuration. When selecting a replacement, confirm that your panel supports 3P operation and matches the 20 A, 120/240 V, 50/60 Hz specifications to ensure proper compatibility and safe operation.
