63 A MCCB with 187 kA interrupting capacity
The Siemens SENTRON 3VA2063-5HN32-0DL0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and 75.6 kA at 500 V, with a 3 kA floor at 690 V. The basic switch core is order code 3VA20635HN320AA0. No communication function or ground-fault monitoring is built in — this is a straightforward thermal-magnetic or electronic-trip MCCB for standard distribution duty.
Dimensions: 86 mm depth, 105 mm width, 181 mm height. The 86 mm depth leaves clearance for rear-connected bus stabs or plug-in base adapters.
Environmental and operating limits
