Ceramic Connector Block (High-Temperature Terminal Block)

Ceramic connector block is a high-temperature screw terminal used to join wires safely in hot environments such as lighting fixtures, ovens, and heaters. It features a heat-resistant ceramic body with brass inserts and secure screw clamping, typically rated around 400V and 10A (model dependent).

Unit: PCS

The ceramic connector block is a heat-resistant electrical connection component designed for safe cable joining and termination in high-temperature environments. Unlike standard plastic terminal blocks, this connector uses a ceramic (porcelain/steatite-type) insulated body that withstands heat without softening, deforming, or degrading—making it ideal for applications such as lighting fixtures, heating elements, ovens, cookers, high-wattage lamps, industrial heaters, and temperature-exposed junction points.

Inside the ceramic body, the block contains metal conductor inserts (typically brass) with screw-clamp terminals that tightly secure the wire ends for stable contact and low resistance. The block design provides separated cable channels to help reduce arcing risk and improve safety where elevated temperatures are present.

Key Benefits

  • High heat resistance: Suitable for hot zones where plastic connectors may fail

  • Strong electrical insulation: Ceramic body provides excellent dielectric performance

  • Reliable screw clamping: Firm conductor grip for stable long-term connections

  • Maintenance-friendly: Can be re-tightened during inspections

  • Common fixture component: Widely used in luminaires, heaters, and high-power appliances

Typical Applications

  • Lamp holders and internal luminaire wiring (especially high-wattage or enclosed fixtures)

  • Electric ovens, cookers, heating appliances, and heating elements

  • High-temperature junction points in industrial equipment

  • Ceramic light fittings, floodlights, and heat-exposed wiring compartments

  • Repair and replacement of burnt/failed plastic connector blocks
