1sna007017r1700 – m4/9.pz15/12
TE Connectivity M4/9.PZ15/12 is a 9 mm screw-clamp component terminal block with integrated surge protection for low-voltage 15 V DC / 12 V AC industrial control and signalling circuits.
Why Choose the TE Connectivity M4/9.PZ15/12 Surge Protection Terminal Block?
The TE Connectivity M4/9.PZ15/12 is a specialised screw-clamp component terminal block with integrated surge protection designed for industrial control, automation and electrical panel applications. Originally associated with the Entrelec terminal block range, this compact component holder provides convenient circuit connection together with transient voltage protection in a DIN rail terminal format.
The M4/9.PZ15/12 incorporates a TVS/Zener-type protective component for circuits operating around 15 V DC / 12 V AC. This enables the terminal block to help suppress transient overvoltage events that could otherwise affect sensitive electronic control, signalling and interface equipment.
Featuring proven screw-clamp connection technology, a compact 9 mm width and grey housing, the M4/9.PZ15/12 is well suited to densely populated control cabinets. Its component-terminal design combines wiring termination and protection functionality within a single modular device, helping simplify panel construction and maintenance.

Reliable Surge Protection for Control Circuits
Transient voltage spikes can occur in industrial electrical systems as a result of switching operations, inductive loads and other electrical disturbances. Sensitive electronic control and signalling equipment can be vulnerable to these short-duration overvoltages, making localised surge suppression an important consideration in reliable control-panel design.
The M4/9.PZ15/12 combines a component terminal block with integrated voltage suppression, allowing protection to be installed directly at the wiring interface. Its compact screw-clamp format makes it particularly useful where reliable termination, straightforward maintenance and space-efficient surge protection are required within industrial control cabinets.
Typical Applications
- Industrial control and automation panels.
- PLC input and output circuits.
- Low-voltage signalling circuits.
- Sensor and instrumentation wiring.
- Electronic control equipment protection.
- Interface and relay circuits.
- Machine control cabinets and electrical distribution systems.
