1sna007019r2100 – m4/9.pz35/24
TE Connectivity M4/9.PZ35/24 1SNA007019R2100 is a DIN rail screw clamp terminal block with integrated bidirectional Zener transient voltage suppression for 24 V AC industrial control and automation circuits.
Why Choose the TE Connectivity M4/9.PZ35/24 Zener Diode Terminal Block?
The TE Connectivity M4/9.PZ35/24, part number 1SNA007019R2100, is a specialised surge protection terminal block with an integrated Zener transient voltage suppressor designed to protect sensitive electrical and electronic circuits against transient overvoltages. Part of the established Entrelec terminal block range, it combines DIN rail terminal connectivity with integrated surge suppression in a compact industrial format.
Designed for control panels, automation equipment and low-voltage electrical systems, the M4/9.PZ35/24 provides a convenient way to incorporate transient voltage protection directly into terminal-level wiring. The integrated bidirectional silicon transient voltage suppressor helps limit potentially damaging voltage spikes, reducing the need for separately mounted protection components and helping create compact, organised control panel installations.
The M4/9.PZ35/24 is intended for 24 V AC circuits and features a 9 mm terminal spacing. Its screw clamp connection technology provides secure conductor termination, while the DIN rail format allows straightforward integration alongside compatible terminal blocks and control components.

Integrated Surge Protection for Industrial Control Circuits
Transient overvoltages can occur in industrial electrical systems when inductive loads are switched or electrical disturbances enter control and signalling circuits. Sensitive automation equipment can be vulnerable to these short-duration voltage spikes, making appropriately selected surge suppression an important part of reliable control panel design.
The TE Connectivity M4/9.PZ35/24 incorporates a bidirectional silicon transient voltage suppressor between the terminal block decks. This integrated design provides localised protection for 24 V AC circuits while retaining the practical installation characteristics of an industrial DIN rail terminal block.
Typical Applications
- Industrial control panels and electrical cabinets.
- 24 V AC control and signalling circuits.
- PLC and automation system interfaces.
- Protection of sensitive electronic control equipment.
- Industrial machinery and production equipment.
- Building automation and process control systems.
- DIN rail mounted electrical distribution and control assemblies.
