Siemens SENTRON 3VA1116-5ED32-0HA0 — 160 A MCCB for Line Protection
The Siemens 3VA1116-5ED32-0HA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a 160 A continuous rating at 40 °C across all three poles, with a slight thermal derating curve that holds 158 A at 55 °C and 150 A at 70 °C — useful to know if the breaker sits in a warm enclosure or near other heat sources. Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — figures that cover most commercial and light industrial fault levels. At 690 V it still interrupts 17 kA, so it can serve 480Y/277 V or 600 V class panels where the available fault current stays within that envelope. The overcurrent release is a TM210 thermal-magnetic type, and the breaker includes a shunt trip (STL) auxiliary release for remote tripping. Insulation voltage is rated 800 V, and maximum power loss at rated current is 38 W — a figure to factor into enclosure thermal calculations.
Sourcing and Lifecycle
For a BOM freeze or a replacement order, the 3VA1116-5ED32-0HA0 is available to quote against an RFQ. Availability and current pricing are confirmed at quote time through the franchise line.
Panel Fit and Dimensions
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting bases and busbar systems. Depth of 70 mm (2.76 in) is compact enough for shallow enclosures; verify the busbar or cable exit clearance against the 70 mm projection from the mounting plane.
