For long cable runs and lower voltage drop, the 460V variant (P\/N 3081620735) is the standard pick on industrial sites; the 230V version is preferred where contractor generators or smaller industrial services are the available power source.\u003c\/p\u003e\n\n\u003ch2\u003eService, Parts, and Support\u003c\/h2\u003e\n\n\u003cp\u003eThe S50N is supported by the same Atlas Copco North American service and parts network that supports the rest of the WEDA range.
