Type series FZEX / FZZX / FZDX and FZVX / FZFX / FZSX 300 - 6000 W - intrinsically safe IP Si Cemented wirewound tubular fixed intrinsically safe resistor in one- up to six-tube design, degree of protection IP20 if mounted on an appropriate surface. Connections at the integrated FRIZLEN DC-POWERSWITCH® in the attached terminal box with cable gland PG9 and PG11 (up to 16 A) or with M12 and PG16-cable gland (>16 A). Switch off by overload. ® if mounted on an appropriate surface ® German patented design no. DGBM 20 2009 015 851.9 Technologies Electrical and mechanical data • intrinsically safe resistor • attention: only suitable for DC voltage up to 850 VDC • integrated FRIZLEN DC-POWERSWITCH up to 25 A • switch off by overload • factory adjusted • connection directly at the FRIZLEN DC-POWERSWITCH • protected against access to hazardous parts • wall mounting or mounting on switch cabinets Intrinsically safe resistor through FRIZLEN DC-POWERSWITCH These type series with overload switch is able to protect the integrated resistors from constant overload and from too high short time peak power, e.g. caused by a false operational mode or a fault by an short circuited chopper transistor. This option for protection not only signals the hardware fault, it switches off the object / the resistor absolutely reliable! Possible damage in the environment by overheating and burning are effectively avoided. The actual fault is reported by potential free N/O and N/C contacts. After a successful fault clearance the DC-POWERSWITCH can be switched on like a normal automatic cutout.
