No. As for an EIS, the UL file will specify this in the respective section's general description unless the mfr has de-rated the unit, then the max operating temp will be in the C of A.

Anyway, the motor is made in Germany and has the CE marking and the UL Recognized component mark. Is this adequate to determine the pump/motor is safe for use or does it still have to pass the locked rotor test? The pump manufacturer says the motor is not thermally protected but has Class F insulation. I will ask if there are any Conditions of Acceptability for the motor. I can also ask if the motor has any component or section of the windings that acts as a fusible link. That would explain why the motor went open circuit before we could get stable temperature readings. Thanks to all. -----Original Message----- From: John Woodgate [mailto:j...@jmwa.demon.co.uk] Sent: Tuesday, January 13, 2015 4:03 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] Safety of Small Motors In message <64D32EE8B9CBDD44963ACB076A5F6ABB026CA9B0@Mailbox-Tech.lecotech.local>, dated Tue, 13 Jan 2015, "Kunde, Brian" <brian_ku...@lecotc.com> writes: >If the winding overheated and melted open, would this be considered a >fire hazard? Not just for that reason. Does it emit flame or flammable vapour? 61010-1 is rather too vague about what constitutes a fire hazard. >Or because something in the motor failed before the winding temperature >reached 190ºC that this motor can be considered inherently safe? Perhaps. The standard allows a thermal cut-out: Motors which, when stopped or prevented from starting (see 4.4.2.5), would present an electric shock HAZARD, a temperature HAZARD, or a fire HAZARD shall be protected by an overtemperature or thermal protection device meeting the requirements of 14.3. Does the manufacturer say whether there is a cut-out? -- OOO - Own Opinions Only. With best wishes.
