That flat 100 A band means you can mount it in a warm panel without losing capacity until the internal air hits 65 °C — common in enclosed switchgear with multiple breakers stacked. The MCS110 overcurrent release is a fixed instantaneous-only (I) type, set at 1600 A (li). No thermal or short-time delay adjustment — this is a switch-disconnector with fault make-and-break capability, not a full selective breaker. Use it where you need a load-break switch with magnetic trip for short-circuit backup, not for cable overload protection. Dimensions are 76.2 mm wide, 129.4 mm tall, and 75.1 mm deep — a compact 3-inch-wide footprint that fits standard SENTRON panel cutouts. Maximum power loss is 18.5 W at rated current — a modest heat load for a 3-pole MCCB. Electrical endurance is 8 000 switching cycles at 480 V, which covers routine switching in a motor branch circuit or distribution panel over many years of normal operation. No auxiliary contacts are included (0 CO contacts), and no communication function or motor drive option is fitted — this is a standalone breaker. Ground-fault monitoring is absent. For a simple branch-circuit disconnect with short-circuit backup, it's a clean drop-in. The storage limit is wider because the breaker isn't dissipating heat when stored — handle it accordingly if it sits in an unheated warehouse.","metaTitle":"SENTRON 3VA4110-1BB34-0AA0 3-Pole MCCB, 100 A, MCS110","metaDescription":"SENTRON 3VA4110-1BB34-0AA0 molded-case circuit breaker, 3-pole, 100 A, MCS110 release, li 1600 A fixed.
