If your panel interior runs hot (say, next to a VFD bank or transformer), the continuous load must be trimmed accordingly. This variant ships with two auxiliary switches and one trip-alarm switch (HQ type) as standard, plus an integrated undervoltage release (UVR). The UVR coil is listed under order code 3VA9608-0BB24 — if you're replacing a unit in a safety circuit that drops the breaker on undervoltage, verify the coil matches your control voltage. The auxiliary contacts give remote status: one for the main contact position, one for the trip-alarm flag. No communication module or ground-fault monitoring is built in; this is a straightforward protective breaker, not a metering device.","metaTitle":"Siemens 3VA1150-5EF36-0CH0 SENTRON MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens 3VA1150-5EF36-0CH0 SENTRON molded case circuit breaker, 50 A rated continuous current, 187 kA interrupting at 240 V.
