The Siemens 3VA2163-5HL36-0AE0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating required up to that ceiling. Its 3-pole construction is designed for line protection, with a rated insulation voltage of 800 V. The interrupting capacity at 240 V is 187 kA, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V. This breaker carries no trip indicator, no undervoltage release, no ground-fault monitoring, and no communication function — it is a straightforward thermal-magnetic or electronic-trip line protector, not a multifunction device.
Mounting and integration
The 3VA2163-5HL36-0AE0 measures 105 mm wide, 181 mm high, and 86 mm deep. These dimensions govern the DIN-rail or panel-mount cutout and the gland-plate clearance. The 86 mm depth is the dimension that determines whether the breaker fits inside a shallow enclosure without the door hitting the handle or the rear terminals contacting the backplane. The 105 mm width is the pole-pitch footprint — three poles at roughly 35 mm per pole, standard for this frame size. The breaker includes 4 auxiliary switches (HQ design) for status feedback to a PLC or annunciator panel.
