Four-pole distribution block TD40A 563740

Distribution block – reliable power distribution

The TD40A distribution block is a solid solution for safe and efficient power distribution in electrical installations. Made of high-quality thermoplastic and brass, it ensures durability and reliable operation. Designed for mounting on a DIN rail or metal plate, it offers flexibility in choosing the installation method. Designed with safety in mind, it has a protective housing and insulating screens that minimize the risk of electric shock.

Construction and parameters

The TD40A block has been designed for ease of installation and use. A transparent protective cover and insulating screens between rows facilitate inspection and identification of connections. It withstands a rated current of up to 40A (IEC) and a short-circuit current of 4.5kA (1s), providing effective protection of circuits against overload and short circuit. The ability to connect wires with a cross-section from 1.5 mm² to 16 mm² (depending on the connection side) gives great freedom in choosing the appropriate cables. Compliance with IEC 60947-7-1 and EN 45545 (HL3 classification for R23 and HL2 for R22) guarantees a high level of safety and compliance with stringent industry requirements.

Application and benefits

The TD40A distribution block finds application in a wide range of electrical installations, both in commercial and industrial construction. It is ideal for distributing power to end users, creating electrical switchboards and in control systems. Its compact dimensions (50 mm depth, 90 mm height, 100 mm width) allow for installation even in limited space. Halogen-free materials and RoHS compliance demonstrate a concern for the natural environment. The self-extinguishing UL94V-0 material further increases safety in the event of a fire.
