Single-pole distribution block 400A 569050

Distribution block – reliable connection for installations up to 400A

This single-pole distribution block, made of tinned copper, is a key element in any electrical installation requiring safe and efficient power distribution. It allows direct connection of copper and aluminum wires, providing flexibility in material selection. The block's design allows for easy connection to build multi-pole distribution systems, ideal for expanded installations.

Construction and application

The block features a tilting and removable cover, making it easier to access connections during installation and maintenance. The ability to mount on a DIN rail or directly onto a plate using screws provides versatility in various switchgear configurations. A transparent protective cover increases safety and allows for visual inspection of the connection status. This is an ideal solution for both professional installers and end-users looking for a reliable element in their installation.

Parameters and benefits – everything that matters

The UD-400A distribution block has been designed with high loads and safety in mind. A maximum rated current of 400A (according to IEC standard) and 335A (UL/CSA) guarantees stable operation even in demanding conditions. Short-circuit strength (Icw 1s: 24.5 kA, Ipk: 51 kA) provides protection against the effects of sudden overvoltages. The use of halogen-free plastic and compliance with UL94V-0 (self-extinguishing) and EN 45545 (HL3 classification for R23 and HL2 for R22) increases the safety of the entire system.

• Connection versatility: Accepts both copper and aluminum wires with cross-sections from 2.5 mm² to 185 mm² (also with ferrules).
• Safety: Compliance with RoHS, UL94V-0 and EN 45545 standards ensures a high level of safety.
• Easy installation: Possibility of mounting on DIN rail or metal plate facilitates integration with existing infrastructure.
• High durability: Rated current up to 400A and high resistance to short-circuit currents guarantee reliable operation in harsh conditions.
• Modularity: Ability to connect blocks to build multi-pole power distribution systems.
• Visual inspection: Transparent cover facilitates inspection of the connection status without disassembly.
