Rating and Application Context
The Siemens 3VA1116-5EF32-0JH0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous current across the 40 °C to 50 °C ambient range, derating to 150 A at 70 °C. The 187 kA breaking capacity at 240 V AC provides substantial fault-interrupting capability for high-available-fault-current installations, per the datasheet. Designed for line protection, this MCCB includes a shunt trip release (STL) and accommodates up to two auxiliary switches plus one trip alarm switch (HQ).
Mounting and Panel Integration
The breaker occupies a 76.2 mm width, 130 mm height, and 70 mm depth footprint. Panel cutout and mounting hole pattern follow the standard SENTRON 3VA frame dimensions; verify back-panel clearance for the shunt trip wiring and auxiliary switch terminations before committing the assembly.
Breaking Capacity by Voltage Level
Breaking capacity varies with system voltage: 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. The 800 V rated insulation voltage supports use in 690 V line-to-line systems where available fault current stays within the 17 kA limit.
Environmental and Auxiliary Specifications
Operating temperature range spans -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. Maximum power loss is 38 W. The breaker includes a trip indicator and voltage trigger function. No undervoltage release, ground-fault monitoring, or communication function is fitted on this variant.
