Siemens 3VA1116-5EF42-0AA0 — 160 A SENTRON MCCB, Line Protection
The Siemens 3VA1116-5EF42-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It is a 4-pole unit rated for 160 A continuous current at 40 °C, with a TM240 thermal-magnetic release that provides both overload and short-circuit protection in a single device. The interrupting capacity is specified at multiple voltage levels: 187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, and 17 kA at both 500 V and 690 V AC. This high-fault rating makes it suitable for installation close to large transformers or in high-capacity switchboards where available fault current is significant. Continuous current derating is documented across the ambient temperature range: the breaker holds 160 A from 40 °C to 50 °C, then gradually derates to 150 A at 70 °C. This allows panel builders to size the breaker for elevated enclosure temperatures without oversizing the frame.
Integration and Mounting
Dimensions: 130 mm high, 101.6 mm wide, 70 mm deep. 4-pole width fits standard SENTRON cutouts. Front-face protection is IP40. No undervoltage release, trip indicator, or communication module included. Maximum power dissipation is 38 W at rated load. This heat must be considered in the enclosure thermal calculation, particularly when grouping multiple breakers in a confined panel.
Compliance and Documentation
Rated insulation voltage 800 V. Operating temperature -25 °C to +70 °C, storage -40 °C to +80 °C.
