SENTRON 3VA — 160 A line protection MCCB
The Siemens SENTRON 3VA2116-5JQ36-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed for line protection in distribution panels. It carries an 800 V rated insulation voltage and a 25.5 W maximum power loss at full load — the thermal budget you need to account for in a sealed enclosure. Breaking capacity is the headline spec here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 690 V the 3.7 kA figure governs; verify your system's prospective fault current at that voltage level before specifying. Communication function is present (the listing confirms it), which means this breaker can integrate with a power monitoring system for remote trip indication and load data.
No end-of-life notice or last-time-buy trigger on this code.
Dimensions are 181 mm height, 105 mm width, 86 mm depth. The 105 mm width is standard for a 3-pole MCCB in this class — it fits the standard mounting footprint in SENTRON distribution boards and most third-party enclosures with a 105 mm cutout.
Thermal performance and operating range
The 160 A rating holds flat from 40 °C through 70 °C ambient — no derating needed across that span, which is unusual for a molded case breaker and simplifies panel thermal calculations. Operating temperature range is -25 °C to 70 °C; storage range -40 °C to 80 °C.
