Cutler-Hammer CHH2100H4X U Two-Pole Circuit Breaker

The Cutler-Hammer CHH2100H4X U is a two-pole circuit breaker rated for 100 A and designed for 120/240 V electrical systems. As a two-pole device, it interrupts current on both hot legs simultaneously to protect circuits that run on split-phase power and to guard against overcurrent conditions. This specific model designation—CHH2100H4X U—conveys its 2P configuration and 100 A rating, making it suitable for high-demand branch circuits in panels that accept this form factor. In normal operation, it functions as the safety switch that automatically trips when current exceeds its rating, helping prevent wiring damage, overheating, and potential fire risk downstream. Use of this breaker is appropriate in installations requiring a 100-amp, 120/240-volt, two-pole protection for individual circuits in residential or light commercial power distributions.
