That matters when you're coordinating with downstream feeders or motor starters and need to ride through inrush without nuisance trips. No undervoltage release, no ground-fault module, no communication function — this is a straight line-protection breaker with a remote-trip option. The 105 mm width and 86 mm depth fit standard SENTRON panel footprints, so it swaps into an existing 3VA cutout without re-drilling gland plates. Full 63 A rating holds through 50 °C ambient. Above that it starts stepping down: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, 53.6 A at 70 °C. If your panel sits near hot motor drives or a sun-baked wall, that derating curve tells you whether you need to bump up a frame size. The maximum power loss is 5.4 W, so heat buildup inside a sealed enclosure is manageable — no forced cooling required for a single breaker at full load. ## What the ETU320 release gives you The ETU320 is an electronic trip unit with adjustable overload (Ir) and short-time (Isd) pickup and delay settings. Unlike a fixed thermal-magnetic breaker, you can dial in coordination with downstream devices without swapping trip packs.","metaTitle":"Siemens 3VA2063-5HL36-0KC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HL36-0KC0 molded case circuit breaker, 63 A rated continuous current, 187 kA interrupting at 240 V.
