Cutler-Hammer CH190U Molded Case Circuit Breaker

Cutler-Hammer CH190U is a molded case circuit breaker rated at 90 A and designed for 120 VAC operation, configured as a 1-pole device that interrupts overcurrent in a single hot conductor within electrical distribution circuits, providing both protection and disconnection capabilities. Part of the Cutler-Hammer CH family, the CH190U is commonly used in low-voltage panels and enclosures to protect branch circuits from short circuits and overload conditions, delivering reliable performance in standard electrical installation environments where single-pole protection is required. The CH190U designation identifies a specific model within the CH series, aligning with Eaton's Cutler-Hammer line of molded case breakers and supporting applications that demand a compact, single-pole, 90 A, 120 V protective device for dedicated circuits. Designed for straightforward integration into compatible panelboards and load centers, this 90 A, 120 V CH190U breaker supports safe isolation of circuits while meeting common industry protection standards for residential, commercial, or light industrial electrical infrastructure.
