1sna007016r1600 – m4/9.pz12/8
TE Connectivity M4/9.PZ12/8 1SNA007016R1600 is a 12 V DC / 8 V AC screw clamp surge protection terminal block with integrated TVS diode protection for industrial control, signalling and automation circuits.
Why Choose the TE Connectivity M4/9.PZ12/8 Surge Protection Terminal Block?
The TE Connectivity M4/9.PZ12/8, manufacturer part number 1SNA007016R1600, is an industrial surge protection screw clamp terminal block designed to protect sensitive electrical and electronic circuits against transient overvoltages. Part of the established Entrelec M4/9 range, it combines secure conductor termination with integrated transient voltage suppression in a compact DIN rail mounted format.
The M4/9.PZ12/8 incorporates TVS diode surge protection, providing fast suppression of potentially damaging voltage transients in low-voltage control, signalling and automation circuits. Integrating the protection component directly into the terminal block helps simplify control panel construction while reducing the need for separately mounted protective components.
Designed for 12 V DC / 8 V AC circuits, the M4/9.PZ12/8 is particularly suitable for sensitive instrumentation, PLC and industrial control wiring. Its compact 9 mm width, grey housing and screw clamp connection system make it well suited to densely populated electrical cabinets where reliable connections and effective transient protection are required.
