1sna007008r0700 – surge protector 38 vdc
TE Connectivity 1SNA007008R0700 M4/9.PV35/24 is a DIN rail industrial surge protection terminal block with an integrated varistor for 35 V DC / 24 V AC circuits and a maximum operating voltage of 38 V DC.
Why Choose the TE Connectivity M4/9.PV35/24 Surge Protection Terminal Block?
The TE Connectivity M4/9.PV35/24, part number 1SNA007008R0700, is an industrial surge protection terminal block with integrated varistor designed to protect low-voltage control and automation circuits against transient overvoltages. Part of the established Entrelec M4/9 Series 7000 range, it combines electrical termination and transient voltage suppression in a compact DIN rail-mounted component.
The M4/9.PV35/24 incorporates a bidirectional metal oxide varistor to suppress short-duration voltage spikes before they can adversely affect sensitive equipment. This integrated approach provides surge protection directly at the terminal level, making it particularly useful in control panels where space-efficient wiring and dependable protection are required.
Designed for circuits with a maximum continuous operating voltage of 38 V DC or 30 V AC, the 1SNA007008R0700 is associated with 35 V DC / 24 V AC applications. It provides a maximum impulse current capability of 500 A with an 8/20 µs current wave, making it a practical protective interface for industrial signalling, instrumentation and automation circuits.

Reliable Transient Protection for Industrial Circuits
Transient overvoltages can be generated by switching operations, inductive loads and other electrical disturbances within industrial systems. These short-duration voltage spikes can affect sensitive control, instrumentation and automation equipment, making local surge suppression an important consideration in dependable panel design.
The M4/9.PV35/24 integrates a varistor directly into the terminal block, allowing transient energy to be suppressed close to the connected circuit. This arrangement combines practical DIN rail termination with surge protection and can reduce the need for separately mounted suppression components within the control cabinet.
Typical Applications
- Industrial control and automation panels.
- PLC input and output circuits.
- Low-voltage signalling circuits.
- Sensor and actuator interfaces.
- Instrumentation and process control systems.
- Relay and interface circuits.
- Electrical panels requiring local transient voltage suppression.
