Cutler-Hammer MSH-5AN Molded Case Circuit Breaker

Cutler-Hammer MSH-5AN Molded Case Circuit Breaker delivers 5-amp overcurrent protection for electrical circuits rated up to 600 volts. This molded case circuit breaker, part of the Cutler-Hammer MSH family, is designed for installation in enclosures, panelboards, and other electrical equipment where compact size and reliable isolation of live parts are required. The MSH-5AN carries a 5 A rating and a 600 V maximum voltage, making it suitable for protecting low-to-medium current branch circuits in industrial and commercial distribution systems. As a molded case device, it provides the essential protection function by interrupting fault currents that exceed its rated setting, helping safeguard wiring and connected equipment in control panels, machine panels, and switchgear applications. The product bears the Cutler-Hammer branding, reflecting a long-standing standard in electrical protection components. The MSH series is commonly used where replacement parts are needed for legacy installations or new panel builds that require a compact MCCB with a precise 5 A protection level. By specifying a 5 A unit within a 600 V class, this breaker aligns with typical small-load circuits that demand reliable, code-compliant overcurrent protection.
