1sna007006r2500 – m4/9.pv15/12
TE Connectivity 1SNA007006R2500 M4/9.PV15/12 is a DIN rail screw-clamp surge protection terminal block with an integrated bidirectional varistor for 15 V DC and 12 V AC low-voltage control circuits.
Why Choose the TE Connectivity M4/9.PV15/12 Surge Protection Terminal Block?
The TE Connectivity M4/9.PV15/12, part number 1SNA007006R2500, is an industrial surge protection screw-clamp terminal block with integrated varistor designed to help protect low-voltage control and automation circuits against transient overvoltages. Part of the established Entrelec M4/9 Series 7000 terminal block range, it combines electrical connection and transient voltage suppression in a compact DIN rail-mounted format.
The M4/9.PV15/12 incorporates a bidirectional metal oxide varistor between its two connection decks, providing local surge suppression directly at the terminal level. This makes it particularly useful for protecting sensitive control, signalling and interface circuits where switching operations or other electrical disturbances can produce potentially damaging voltage transients.
Designed for low-voltage circuits, this version is identified for 15 V DC / 12 V AC applications. The terminal block has a 9 mm spacing and grey body, providing a compact solution for incorporating surge protection into industrial control panels and electrical distribution assemblies.

Reliable Surge Protection for Control Circuits
Transient overvoltages generated by switching loads, inductive equipment and other electrical disturbances can affect sensitive automation and control components. A varistor-equipped terminal block provides a convenient way to suppress these short-duration voltage spikes close to the connected equipment while retaining the practical wiring functions of a conventional terminal block.
The M4/9.PV15/12 uses a bidirectional metal oxide transient voltage suppressor between its two decks. By integrating protection directly into the terminal assembly, it can simplify panel wiring and reduce the need for separately mounted suppression components in low-voltage industrial circuits.
Typical Applications
- Industrial control and automation panels.
- PLC input and output circuits.
- Low-voltage signalling circuits.
- Sensor and actuator connections.
- Relay and interface circuits.
- Instrumentation and process control equipment.
- Electrical panels requiring local transient voltage suppression.
