Mechanical life is typical at 10 million operations, so this contactor is suited for frequent cycling in conveyor or pump applications, not just infrequent isolation.","metaTitle":"Siemens 3RT2027-1FB48-0ME1-ZX95 SIRIUS Power Contactor, S0,","metaDescription":"Siemens SIRIUS 3RT2027-1FB48-0ME1-ZX95 power contactor, size S0, 24 VDC coil, 480 V rated 27 A, screw/snap-on DIN rail, IP20.
