1sna007004r2300 – m4/9.pv5/4

Why Choose the TE Connectivity M4/9.PV5/4 Terminal Block?

The TE Connectivity M4/9.PV5/4, part number 1SNA007004R2300, is a specialised screw-clamp terminal block with integrated varistor surge protection designed for industrial control, signalling and electrical panel applications. Part of the established ENTRELEC terminal block range, it combines secure conductor termination with protection against transient overvoltages.

The M4/9.PV5/4 incorporates a bidirectional metal-oxide varistor between its two decks, allowing transient voltage spikes to be suppressed directly at the terminal connection. This integrated approach reduces the need for separately mounted suppression components while helping protect sensitive control and electronic equipment from potentially damaging voltage transients.

Designed for low-voltage circuits, this version is rated for 5 V DC / 4 V AC applications and uses a grey terminal body. Its compact 9 mm spacing and DIN-rail terminal format make it particularly suitable for organised installation in control cabinets, machinery panels and industrial automation systems.

Reliable Surge Protection for Control Circuits

Transient overvoltages generated by switching operations, inductive loads and other electrical disturbances can affect sensitive control and electronic equipment. Installing surge suppression close to the circuit connection helps limit these short-duration voltage spikes before they reach connected components.

The TE Connectivity M4/9.PV5/4 integrates its varistor directly into the terminal block, providing both conductor termination and transient suppression in a compact DIN-rail assembly. This makes it particularly useful where panel space, organised wiring and dependable low-voltage circuit protection are important.

Typical Applications

• Industrial control cabinets and electrical panels.
• Low-voltage control and signalling circuits.
• PLC and industrial automation systems.
• Protection of sensitive electronic control circuits.
• Machine building and manufacturing equipment.
• DIN-rail terminal assemblies requiring integrated surge suppression.
