The 63 A rating holds steady from 40 °C up to 50 °C, then derates to 60.48 A at 55 °C and 56.7 A at 70 °C — so in a warm enclosure you size the breaker for the actual ambient, not the nameplate. The 800 V rated insulation voltage (Ui) means this MCCB can be used on 480 V, 600 V, and even 690 V systems (where interrupting drops to 52.5 kA). The 20 000 mechanical endurance cycles reflect a robust mechanism for frequent switching in motor starter duty. Dimensions are 181 mm high by 105 mm wide by 86 mm deep — this is a standard SENTRON 3VA2 frame size, so it fits the same panel cutouts and bus-bar spacing as other 3VA2 breakers. The auxiliary contact version ships with 2 HQ (high-availability) switches pre-installed, saving a slot in the accessory compartment.","metaTitle":"Siemens 3VA2163-7MS36-0DC0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens 3VA2163-7MS36-0DC0 SENTRON molded case circuit breaker, 63 A rated, 330 kA interrupting at 240 V.

The key difference is the trip unit: the -7MS36-0DC0 uses an ETU310M electronic trip unit configured for starter protection, while the -8HM32-0AA0 uses a different trip unit design. Both share the same 63 A frame, 3-pole construction, and 330 kA interrupting capacity at 240 V, but the trip curves and protection profiles differ — verify coordination before substituting."},{"question":"How do I get current pricing and availability for 3VA2163-7MS36-0DC0?","answer":"Submit an RFQ through this listing.
