Safe electrical connectors. The material of the electrical connectors is flame-retardant PA66 (orange button) / flame-retardant PC (transparent shell), which is corrosion-resistant, aging-resistant, and has a long service life. The PC material is transparent and has a test hole on the top of this connector. Highly conductive terminals. The internal conductive material of these terminals is cupronickel, providing good conductivity; no soldering or tape is required. Rated voltage: 250V, rated power: 4kV, rated current: 32A. Easy installation and reusable electrical connections. The terminal block allows for easy operation: open the orange lever, connect the wire, close the orange lever, and the wire connection is complete. The spring clip material is stainless steel; The terminal block is reusable. Application of electrical connectors: These connectors can be used at home and in the workshop. Ideal for parallel circuits and multi-group switches, it is suitable for rigid cables from 0.08
