Terminations

Stock LA Option Post terminals provide a quickconnection with ring or fork connectors, or buss strips. Threaded 10-24 studs or optional metric (M5X.8) are provided with double nuts and washers. Post terminals have a threaded length of 14 mm (0.5625 in.) and require 32 mm (1.25 in.) clearance from the cylinder. Maximum amperage for post terminals is 35 amps and they can withstand up to (61.0 Newton- Meter) 45 in-lbs of torque. The increased torque is possible due to the unique add-on lead cap design,whichmakes the cap a separateentity from the heater. This meansallofthe torquecarrying capability ismaintained within the cap design, allowing the terminal hardware to be torqued to a specific setting and tested prior to connection to the heater.The welded electrical connection tothe heater is superior to crimped or staked connections which can loosen and oxidize during operation.To order, specify See page 38 forminimum/maximumdimensional requirements. 42
