Product overview and key ratings
It carries a 63 A rated current at 40 °C through all four poles, with no derating needed up to 50 °C — at 55 °C it still holds 62 A, and at 70 °C it delivers 58 A.
Breaking capacity and application context
Breaking capacity is rated per the evidence at 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 4-pole configuration suits three-phase systems with a fully switched neutral, common in North American and IEC distribution.
Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth. The width of 101.6 mm (4 inches) is the standard footprint for a 4-pole MCCB in the SENTRON 3VA frame, so it fits existing panel cutouts and busbar layouts designed for that pole count.
The SENTRON 3VA series carries full IEC/EN 60947-2 certification for molded case circuit breakers. The rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to +70 °C, with storage from -40 °C to +80 °C. Maximum power loss is 17.3 W. The breaker does not include an undervoltage release, trip indicator, or ground-fault monitoring — these are external accessories if required.
