1sna007020r2600 – m4/9.pz48/36

Why Choose the TE Connectivity M4/9.PZ48/36 Surge Protection Terminal Block?

The TE Connectivity M4/9.PZ48/36, part number 1SNA007020R2600, is a specialised surge protection terminal block with an integrated TVS diode designed to protect sensitive electrical and electronic circuits against transient overvoltages. Part of the established Entrelec terminal block range, it combines industrial screw clamp connectivity with integrated transient voltage suppression in a compact DIN rail mounted format.

Designed for control panels, automation equipment and low-voltage electrical systems, the M4/9.PZ48/36 provides a convenient way to incorporate transient protection directly into terminal-level wiring. The integrated protection component helps clamp potentially damaging voltage spikes, reducing the need for separately mounted suppression devices and supporting compact, organised electrical panel designs.

The M4/9.PZ48/36 is designed for circuits operating at up to 48 V DC / 36 V AC. Its screw clamp terminal construction provides dependable conductor termination, while the component-holder design enables surge protection to be integrated directly into industrial control and automation wiring.

Integrated Surge Protection for Industrial Control Circuits

Transient overvoltages can occur in industrial electrical systems when inductive loads are switched or disturbances enter control, signalling and automation circuits. Sensitive electronic equipment can be vulnerable to these short-duration voltage spikes, making appropriately selected transient suppression an important part of reliable control panel design.

The TE Connectivity M4/9.PZ48/36 incorporates surge suppression directly into a screw clamp component-holder terminal block. This integrated arrangement provides localised transient protection for compatible 48 V DC and 36 V AC circuits while retaining the practical installation characteristics of an industrial DIN rail terminal.

Typical Applications

• Industrial control panels and electrical cabinets.
• 48 V DC and 36 V AC control circuits.
• PLC and industrial automation 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.
