SENTRON 3VA1116-3EF32-0KH0 — 160 A Line Protection MCCB
The Siemens 3VA1116-3EF32-0KH0 is a SENTRON 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C, configured as a line protection device with a TM240 thermal-magnetic release. Its interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — figures that govern its application in high-fault panels where selectivity and SCCR headroom are critical.
Rated continuous current Iu is 160 A, holding flat through 50 °C ambient. Above that, derate to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C — the thermal curve you need for a tightly packed panel or elevated ambient near a furnace line. Verify the 160 A frame matches your load before specifying.
The 3-pole footprint fits standard SENTRON mounting positions in a distribution board or motor control center.
For a critical-spare holding on a legacy SENTRON install, this is the direct drop-in. Keep one in the cabinet before it fails — no substitute needed while it is current-production.
