These alloy sheathed alternatives to ceramic bobbin heaters are designed to improve service life where ceramic bobbins will deteriorate through physical damage. They insert into a 50mm nominal diameter sheath (refer over page). All units consist of 3 ‘U’ shaped elements each rated at 240volts (Except the 15kW 40255×60.T41.150). They may therefore be wired for 415/240V star connection or 240V single phase. Min. length available 300mm penetration. Max power density 31kW/m².
