Type BCA | Type BCB | Type BCC |
Basic model for general applications in electrothermics |
Includes a 4 feet base to allow a remote mounting of the mounting surface and avoid the heat conduction from the support. Suitable for mounting on furnace walls. | Includes a ceramic protective cap secured by two M4 screws. It protects against hand contacts, and also prevents short circuits due to the fall of conductive materials in case of fire. Developed for road and railway tunnels. |
Applications: These high quality electrical connection blocks allow efficient and easy wiring connections of ovens, infrared heaters, quartz tube heaters in furnaces, kilns, catering equipment, but also in equipment that must withstand fire whilst maintaining their function such as road and railway tunnels and military equipment
Specially designed to provide increased resistance to high temperatures, they can withstand 500 °C (900 °F) continuously and 700 °C (1292 °F) peak. They retain their mechanical properties, electrical insulation and connectivity after 2 hours at 920°C (Fire simulation test)
Typical insulation resistance between two terminals:
- at 100°C (212°F): 1500 Mohm
- at 500°C (900°F): 1000 Mohm
- at 700°C (1290°F): 650 Mohm
- at 900°C (1650°F): 10 Mohm
Dielectric strength: 15 kV / mm
Screws: M4x8, 304 stainless steel, with spring washer against loosening at high temperature. Recommended torque 13~ 20 DaN.cm Two possible types of screw heads: Phillips or slot upon DIN84
Terminals: 304 Stainless steel, 16mm² gauge
Saddles: 304 Stainless Steel, with or without safety tab against wire shearing
Max wire gauges (per terminal, wires inserted between saddle and connector plate):
- 1 stranded wire 5.1mm (max 10 mm² or AWG8)
- Two stranded wires 2.9 mm (2 x 6mm², 2x AWG 10)
- Two rigid wires max 3 mm (2 x 6 mm², 2 x AWG 10)
Current carrying capacity: 32A per terminal
Maximum Operating Voltage: 750V (insulation distance greater than 10mm between mounting board and terminals, and between terminals). Special care must be taken to avoid reducing the isolation distances during assembly by the use of inappropriate mounting screws or poorly stripped or poorly insulated cables.
Maximum ambient temperature:
- Permanent: 500°C (900°F)
- In peak short duration: 700°C (1292°F)
- Fire: 920°C (1690°F) for two hours (Afterwards equipment must be replaced, but it retains its main characteristics during the fire).
Applicable standards: (IEC) EN60998-1 ; (IEC) EN60998-2-1 (August 1993) ; NFC32-070.

Elevated terminal plastic connection blocks
In electrothermal connection applications, especially in immersion heater connection boxes appear specific constraints: high ambient temperature, frequent thermal cycles, and confined space around the ends of the heating elements and their terminals, making difficult to the user to make connections. These terminals have been developed to address these constraints.

Technical introduction of connection blocks made in ceramic and polyamide
Ceramic was the first insulating material used in the electrical connection terminals. Mechanically resistant, exceptionally fire resistant, excellent electrical insulator, it had all the qualifications. Produced from locally available raw materials, ceramic and porcelain glazed electro-technical parts were essential in the beginnings of electricity until the appearance of Bakelite in the 1930s, then of engineered thermoplastics to 1960.
