Description
Product Overview
JANDECCN DIN rail terminal blocks are engineered for safety and reliability in electrical connections. Constructed from insulated, flame-retardant materials, they resist corrosion, aging, and high pressure, ensuring long-term durability. With dimensions of 1.69 x 1.69 x 1.22 inches and a weight of 12.63 ounces, these blocks feature a strong structure that locks firmly onto DIN rails. The model JKV121-50 supports solid wires from 0.2-4.0mm² (24-12 AWG) and flexible wires from 0.2-2.5mm² (24-14 AWG), making them versatile for various applications. Each block is independently shielded to prevent interference, and the package includes 50 units for ample supply.

Usage
These terminal blocks are ideal for home appliances, lighting systems, electrical control panels, power supplies, sockets, switches, and machinery.
