The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Those numbers mean it can clear a fault upstream of a 2 MVA transformer at 240 V without the arc re-striking, which is the kind of SCCR headroom a site electrical engineer needs for a service-entrance or main-feeder position. At 101.6 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits a standard 4-pole mounting footprint. The TM240 release is fixed-thermal, not electronic, so there's no phase-failure detection or communication function on this variant. ## What this MCCB is used for As a line-protection MCCB, it sits between the transformer secondary and the distribution bus, or as a main breaker in a panel feeding motor control centers and lighting sub-panels. The 4-pole configuration handles three-phase plus neutral, common in North American 120/208 V and 277/480 V systems as well as international 400/690 V networks. The undervoltage release lets a safety circuit or emergency-stop chain trip the breaker open when control voltage drops — a standard requirement in machine safety circuits per IEC 60204-1.","metaTitle":"SENTRON 3VA1116-5EF42-0CA0 MCCB, 160 A, 4-Pole, 187 kA at 24","metaDescription":"SENTRON 3VA1116-5EF42-0CA0 molded case circuit breaker, 160 A rated continuous current, 4-pole, TM240 release, 187 kA at 240 V.
