Terminal Connection 2 Pin Male Plug - 16Amps SS 304 Terminal Box with Screw Post Terminals and 10” Long Cable Screw Post Terminals with Ceramic Protection Caps Metal Braided Leads Exit through edges on both sides of gap Electric Terminal Connections for Band Heaters will be Provided with SS protection caps at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified All Band Heaters above Dia 60mm will be provided with Screw Stud Electric terminal connections covered with SS Protection Caps All Mica Band Heaters Below 60mm Dia will not have Screw Post Terminals
Thermocouple Holes/‘U’ Slots/Cutout Normally required for clearance of the thermocouple probes or holding bolts. Oversize gap can in many cases serve the same purpose, using the centre of the gap as a starting point, specify location in terms of degrees and size of the hole or cut-out. Minimum of ½” is required from the hole to the edge of the heater. For critical hole or cut-out locations, please provide detailed drawing. Note: As far as possible please avoid thermocouple holes. Try and locate them in the heater gap, since holes in the heater body complicates the internal wiring resulting in less heating area and also turns out to be more expensive. All Thermocouple Holes for Band Heaters (if required) will be Provided at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified along with drawing.
Two Piece Construction Available on any screw or lead termination or clamping variation. Used on large cylinders or where heaters cannot be slipped over end of cylinders. Two piece Band Heaters are normally rated at half total wattage and full line voltage. Limitations: Min. I.D. : 3” Min. Width: 1½”
