The Siemens SENTRON 3VA2163-7MN32-0JH0 is a 3-pole 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 needed up to that ceiling. Its interrupting capacity hits 330 kA at 240 V, which means it can clear a fault at that level without the arc flashing over to adjacent buswork. That kind of short-circuit rating is what you spec when the available fault current at the panel is high and you want a single device to handle it rather than cascading upstream breakers. This is the motor protection design variant, so it includes phase failure detection — a feature that trips the breaker if one phase drops out, preventing single-phasing damage to a motor load. The auxiliary switch block is populated with 2 auxiliary switches plus 1 trip alarm switch, and the shunt trip release (STL) is factory-installed, giving you remote trip capability without adding a separate module. The basic switch itself is order code 3VA2163-7MN32-0AA0, meaning this -0JH0 suffix adds the auxiliary and shunt trip hardware at the factory.
Panel Fit and Integration
Dimensions are 86 mm deep by 105 mm wide by 181 mm tall. That 105 mm width is standard for a 3-pole SENTRON 3VA frame — it occupies three 35 mm DIN module positions. The 86 mm depth means it clears most standard enclosure backpanels without needing a gland plate extension. Mounting is via the rear DIN rail clip; no additional panel cutout required. The shunt trip wiring lands on the integrated terminal block, and the auxiliary switch contacts are accessible at the front of the breaker for control wiring.
Breaking Capacity Profile
The interrupting capacity varies significantly with system voltage: 330 kA at 240 V, 242 kA at both 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V — down to 3.7 kA — is typical for an MCCB with this frame size; at that voltage the arc extinction limits the fault-clearing capability. For 690 V applications, verify that the available fault current at the panel is below that threshold. The time-delay settings range from a minimum of 4 s to a maximum of 17 s, giving you a window to coordinate with downstream devices on a selective trip scheme.
Environmental and Electrical Ratings
Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. Maximum power loss is 4 W — negligible for panel thermal budgeting. The undervoltage release is not fitted, and there is no ground-fault monitoring module. Communication function is absent, so this is a standalone thermal-magnetic breaker, not a power-metering or networked device. The trip indicator and voltage trigger are both present, giving a local visual trip flag and a remote signal from the shunt trip coil.
