The 65 kA Icw short-time withstand (0.5 s) lets it ride through a delayed trip without damage, so you can coordinate with downstream feeders. The drawout chassis mounting means the breaker can be racked out for maintenance or replacement without de-energizing the bus — a standard requirement for main and tie breakers in switchgear. The drawout mounting and chassis support place this breaker in a metal-enclosed low-voltage switchgear lineup — ANSI-rated, typically for main, tie, or large feeder positions. The 3-pole configuration with push-button control suits distribution applications where remote or local switching is needed. ArcBlok technology is integral to the arc chamber design, reducing arc energy during interruption and extending contact life.","metaTitle":"Schneider Electric LV839310 Masterpact MTZ3 50 HA, 5000 A, 3","metaDescription":"Schneider Electric LV839310 Masterpact MTZ3 50 HA switch disconnector. 5000 A rated, 65 kA Icu breaking capacity, 3-pole drawout.
