1sna007018r2000 – m4/9.pz24/15
TE Connectivity M4/9.PZ24/15 is a screw-clamp component terminal block with integrated Zener surge protection for 24 V DC / 15 V AC industrial control, signalling and automation circuits.
Why Choose the TE Connectivity M4/9.PZ24/15 Surge Protection Terminal Block?
The TE Connectivity M4/9.PZ24/15 is an industrial screw-clamp component terminal block with integrated Zener surge protection designed for low-voltage control, signalling and automation circuits. Part of the established Entrelec M4/9 terminal block range, it combines secure conductor termination with transient overvoltage suppression in a compact modular format.
The M4/9.PZ24/15 incorporates a TVS/Zener protective device for circuits operating at approximately 24 V DC / 15 V AC. This integrated protection helps limit transient voltage spikes before they can reach sensitive electronic equipment such as PLC interfaces, sensors, instrumentation and control electronics.
Designed for industrial electrical panels, the terminal block uses proven screw-clamp connection technology and a grey component-holder housing. By integrating surge suppression directly into the terminal level, the M4/9.PZ24/15 provides a convenient solution for protecting low-voltage circuits while maintaining an organised and serviceable control-panel installation.

Reliable Surge Protection for Low-Voltage Control Circuits
Industrial control circuits can experience short-duration voltage transients caused by switching operations, inductive loads and other electrical disturbances. These overvoltages can interfere with or damage sensitive electronic equipment, particularly PLC inputs and outputs, sensors, instrumentation and electronic interface circuits.
The M4/9.PZ24/15 places a Zener-based suppression device directly at the terminal connection point, allowing transient protection to be incorporated into the wiring system without requiring a separate standalone protection module. This makes it particularly useful for compact industrial panels where dependable connections, straightforward maintenance and effective circuit protection are required.
Typical Applications
- 24 V DC industrial control circuits.
- PLC input and output protection.
- Industrial automation panels.
- Sensor and actuator circuits.
- Instrumentation and measurement systems.
- Low-voltage signalling circuits.
- Machine control cabinets.
- Electronic interface and control equipment.
