ABB S4HD-3P-250A-NA is a molded case circuit breaker from the SACE Isomax family, designed as a non-automatic switch for primary circuit isolation and manual switching without overcurrent protection. It is rated for 600V AC, 250A continuous current, and 3-phase operation, with a high interrupting capacity of 65kA at 480V. The unit features a compact S4 frame size, weighs 10 lb, and uses a bolt-on connection for secure panel mounting in a 3-pole configuration. It complies with industry standards for industrial switchgear and is intended for use in distribution panels requiring manual load control. Typical applications include main disconnects, feeder switches, and backup isolation in commercial and industrial power systems.
