Accessory Type series FPS FRIZLEN DC-POWERSWITCH. Adjustable protection of loads at DC voltage up to 850 V. Loads with a rated current from 1,0 up to 40 A can be connected. The tripping device and the characteristics are similar to motor-circuit switches. 10 ranges of adjustment are available. The DC-Powerswitch reacts on thermal overload, also electromagnetically on short circuit and on the multiple of the rated current. Registration: German patented design no. 20 2009 015 851.9 UL registration according to UL1077 with E357442 Electrical and mechanical data overload protection short circuit up to 5 kA, 1ms re-switchable 1,0 - 40 A rated current, DC1 up to 850 V DC for installation into a switch cabinet or a terminal box of a FRIZLEN power resistor for intrinsically safe resistors with signal contact Attention: Please pay attention for connecting the correct polarity! FPS 1.6 – 25 These overload switches are developed 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 signals not only the hardware fault, it switches off the object / the resistor absolutely reliable! Possible damage in the environment through overheating and burning are effectively avoided. The actual fault is reported over potential free N/O and N/C contacts. After a successful fault clearance the DCPowerswitch can be switched on like a normal automatic fuse.
