Very High Temperature Ceramic Terminal Blocks TB2J-HT and TB3J-HT


 


Description


These high quality electrical connection blocks make wiring connections to heaters efficient and easy. Ovens, furnaces, kilns, infrared heaters, quartz tube heaters, catering equipment, etc.

 


General Specifications



  • 32 Amps

  • Fitted with Stainless Steel connectors

  • Can withstand long term temperatures of 900°F (500°C)

  • Can withstand 1292°F (700°C) during short time periods


 


Specifications TB2J-HT Ceramic Terminal Block



  • Dimensions: 40 x 32 x 21 mm (+/-1mm)

  • Particularities: designed for increased resistance to permanent high temperature: Ceramic has 4 legs to avoid fixing plate temperature conduction to ceramic. Stainless steel saddles have a cable bending protection blade.

  • Ceramic part characteristics:

    • Material: Ker 600 ceramic (high alumina content)

    • Bulk density: >3g/cm3

    • Water absorption: 0%

    • Flexural strength: > 200 Mpa/cm²

    • Coefficient of thermal expansion: < 8 10-6 mm/°C( 20-100°C)

    • Volume resistivity: >1013 ohms.cm at 100°C

    • Dielectric strength: 15 Kv/mm



  • Metal parts:

    • Screws: M4 x 8 , Aisi 304 stainless steel. Maximum torque allowed: 1.2Nm

    • Saddles and washers: Stainless steel Aisi 302

    • Terminals: 8 x 2mm Aisi 304 Stainless steel



  • Inscriptions:

    • Front: 1,2

    • Back: JPCI



  • Fixing:

    • 1 fixing hole dia 5 mm for 4mm diameter screws or equivalent



  • Maximum ambient temperature: long term  500°C  (900°F) . Can withstand 700°C during short time.

  • Electrical characteristics: (Wires inserted between saddle and connector plate).

    • Maximum wire diameter (each connector):

      • Accepts  1 stranded wire  5.1 mm dia. (max 10mm² or AWG 8) or 2 stranded wire dia 2.9 (6mm², AWG 10)

      • Accepts  2 plain wire diameter up to 2.2 mm dia ( 2 x 4mm² or 2 x AWG 12)



    • Maximum rating: 32A

    • Voltage:  Up to 750V  (insulation distance >10mm between phases, and also between fixing face and terminals.  Particular care must be taken selecting central fixing screw dimensions to avoid reducing  insulation distance under value requested by applicable standard.



  • Unit net weight: 56 grs (+/-5 grs)
