£0.00
The TE Connectivity M4/9.PV12/8, manufacturer part number 1SNA007005R2400, is a specialised screw-clamp terminal block with integrated varistor surge protection designed for industrial control, signalling and electrical panel applications. Part of the established ENTRELEC terminal block range, it combines dependable conductor termination with transient overvoltage suppression in a compact DIN-rail format.
The M4/9.PV12/8 incorporates a bidirectional metal-oxide transient voltage suppressor between its two decks. This integrated varistor helps limit short-duration voltage spikes before they can reach connected control and electronic equipment, providing surge protection directly at the terminal connection while reducing the need for separately mounted suppression components.
Designed for 12 V DC / 8 V AC circuits, the M4/9.PV12/8 features a 9 mm terminal spacing and compact dimensions of approximately 65.5 × 9 × 52 mm. Its grey body and screw-clamp connection make it a practical solution for organised low-voltage wiring in machinery, control cabinets and industrial automation systems.
Transient overvoltages caused by switching operations, inductive loads and other electrical disturbances can disrupt or damage sensitive control electronics. Installing surge suppression close to the electrical connection helps limit these short-duration voltage spikes before they reach downstream components.
The TE Connectivity M4/9.PV12/8 integrates a bidirectional metal-oxide varistor directly into the terminal block. This provides both conductor termination and transient suppression in a compact assembly, making it particularly useful where panel space, organised wiring and dependable protection of low-voltage control circuits are important.
