Three poles, shunt trip (STL) fitted, plus two auxiliary switches and a trip alarm switch HQ. ## Interrupting capacity and selectivity coordination At 415 V the breaker clears 121 kA; at 500 V it still handles 75.6 kA. The 690 V rating drops to 3.7 kA — that's the limit for a 690 V line-side fault, so if your system runs at 690 V, verify the available fault current stays under that figure. The minimum rated current is 95 A, which means the breaker's magnetic trip threshold starts at that level — the 63 A continuous rating is the thermal pickup, not the instantaneous magnetic floor. The shunt trip (STL) allows remote tripping from a safety circuit or E-stop relay; wire it per the terminal diagram on the breaker side. Two auxiliary switches plus a separate trip alarm switch HQ give three independent signal paths — one for the PLC status input, one for a panel lamp, one for the alarm annunciator. Communication function is present, so the breaker can report status over the bus if the system uses the 3VA2 communication module.","metaTitle":"Siemens 3VA2163-5JQ32-0HH0 SENTRON MCCB, 63 A, 3-Pole, Line","metaDescription":"Siemens 3VA2163-5JQ32-0HH0 SENTRON molded case circuit breaker, 63 A rated at 70 °C, 3-pole, line protection with shunt trip and communication.
