Why Choose the TE Connectivity 1SNA115591R0400 M4/6.DE1.D1 Diode Block?
The TE Connectivity 1SNA115591R0400, also identified as M4/6.DE1.D1, is a grey diode component terminal block from the ENTRELEC SNA screw-clamp terminal block range. Designed for industrial electrical panels, machinery and automation systems, it combines field wiring termination with an integrated diode function in a compact DIN rail-mounted format.
The M4/6.DE1.D1 uses dependable screw-clamp connections and is designed as a component-holder terminal for applications where a diode is required within the control circuit. Incorporating the electronic component directly into the terminal assembly can simplify panel wiring, improve circuit organisation and reduce the need for separately mounted components.
With a rated current of 20 A, rated voltage of 500 V and a rated cross-section of 4 mm², this terminal block provides a compact solution for industrial control wiring. Its 6 mm spacing and compatibility with G32, TH 35-7.5 and TH 35-15 mounting rails support flexible installation within electrical cabinets.
