SENTRON 3VA1116-5EF46-0AA0 — 4-Pole MCCB for Line Protection
The Siemens SENTRON 3VA1116-5EF46-0AA0 is a 4-pole molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a continuous current rating of 160 A at 40 °C, with a thermal-magnetic TM240 trip unit that offers an adjustable I-t characteristic for coordinating with downstream loads. Breaking capacity is specified across multiple voltage levels: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. This range makes the breaker suitable for high-fault-current installations where selectivity with upstream devices is required. Rated insulation voltage is 800 V, and the front face carries IP40 protection — sufficient for enclosed panel mounting where the breaker is not exposed to dripping water or tool entry.
Thermal Derating and Panel Integration
The breaker maintains its full 160 A rating from 40 °C through 50 °C. Above that, derating applies: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. For a panel designer, this means the breaker can be installed in a warm enclosure without oversizing, provided ambient temperature stays within the -25 °C to 70 °C operating range. Maximum power loss is 38 W, which contributes to enclosure heat load. Include this figure in thermal calculations for sealed cabinets.
Lifecycle and Sourcing
This MCCB has no communication function, no undervoltage release, no voltage trigger, no trip indicator, and no ground-fault monitoring. It is a base-line protection device — specify add-on modules or a different variant if those features are required.
Compliance and Documentation
As a Siemens SENTRON product, the 3VA1116-5EF46-0AA0 is designed to meet IEC 60947-2 and relevant UL/CSA standards for molded case circuit breakers. Compliance documentation including RoHS and REACH declarations is available from Siemens upon request. For audit purposes, the manufacturer provides a declaration of conformity and test certificates traceable to the order code. Storage temperature range is -40 °C to 80 °C, exceeding the operating range — this governs handling and warehousing, not in-service conditions.
