Material: Brass Terminal + PA66 Flame Retardant Housing
Certification: CE, RoHS
Feature: Barrier Isolation, High Safety, Large Current Capacity
Type: Barrier Type Terminal Block
Application: Power Distribution Box, Household Appliances, Electrical Equipment
Barrier-type terminal block adopts isolated barrier structure to prevent electric leakage and short circuit. Equipped with high conductivity brass conductor and UL94 V0 flame retardant PA66 housing.
All products comply with CE and RoHS safety standards. The reinforced screw clamping structure ensures firm wire connection, good pressure resistance and large current carrying capacity.
Clear barrier isolation design improves operation safety, suitable for high current and dense wiring occasions. Widely used in distribution boxes, home appliances, power supplies and industrial electrical equipment.
Barrier Type Terminal Block — Panel Mount, Screw Connection
Barrier terminal blocks put an isolation wall between adjacent poles — the reason they are specified wherever high current, high voltage or dense wiring demands extra safety. The barrier prevents arcing and flashover between adjacent conductors, and the open construction makes every connection visible and inspectable at a glance.
The reinforced screw clamping structure handles large cable cross-sections with firm, re-tightenable contact force, and the panel-mount design installs directly into distribution boxes and equipment enclosures.
Key Features
- Barrier isolation between poles — prevents electric leakage and short circuits
- Large current capacity — reinforced screw clamp for heavy wiring
- Panel mount — direct installation into distribution boxes and appliances
- Brass terminal + PA66 V-0 housing — CE, RoHS compliant
