Low-performance cartridge heaters

 

Low-performance cartridge heaters, compared with high-performance and medium-performance cartridge heaters, are suitable for applications with low voltage, or low working temperature, and a low watt density of cartridges (up to 5 W/cm2).

Maximum recommended voltage 240 V 240 V 400 V 400 V 400 V 400 V
Maximum recommended current – outlets connected outside the cartridge heater 10 A 12 A 15 A 25 A 27 A 30 A
Maximum recommended input power (at 230 V) – outlets connected outside the cartridge heater 2,300 W 2,760 W 3,450 W 5,750 W 6,200 W 6,900 W
Maximum recommended current – outlets with insulation inserted into the cartridge heater 6 A 11 A 15 A 19.5 A 19.5 A 19.5 A
Maximum recommended input power (at 230 V) – outlets with insulation inserted into the cartridge heater 1,380 W 2,530 W 3,450 W 4,480 W 4,480 W 4,480 W
