It is built on the IEC frame 160 platform and ships without overload or short-circuit protection elements, so it functions purely as a load-break disconnect for isolation and switching duty. ## Undervoltage Release and Auxiliary Switching ## Mechanical Life and Power Loss Typical mechanical service life is 15,000 operating cycles — adequate for isolation duty where the disconnect is operated a few times per shift, not for high-frequency motor starting. Maximum power loss is 38 W at rated current, which factors into enclosure thermal calculations if multiple units are ganged in a small cabinet. The mechanical service life is 15,000 cycles typical.","metaTitle":"Siemens 3VA1163-1AA36-0CH0 Switch Disconnector, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1 switch disconnector, 63 A rated current, 3-pole, 690 V AC / 500 V DC, with undervoltage release.
