Covering motor currents of 62 … 73 A, the Siemens 3RV2032-4KA10 is a 3-pole SIRIUS 3RV2 motor protection circuit breaker, size S2, CLASS 10, with an instantaneous short-circuit release of 949 A. Per Siemens it suits motors of about 37 kW at 400 V and has a rated short-circuit breaking capacity (Icu) of 100 kA at 400 V.<\/p>\n
Set the overload dial to the full-load current on the motor rating plate. If the breaker trips repeatedly, check the motor, the mechanical load and the supply phases before raising the setting.<\/p>\n

Choose the setting range so that the motor full-load current sits roughly in the middle of the dial; this leaves room for adjustment.<\/p>\n Frequently asked questions<\/h3>\n |
