1sna195212r1000 – m6/8 stp/tr block.

Why Choose the TE Connectivity 1SNA195212R1000 M6/8.STP Test Disconnect Terminal Block?

The TE Connectivity 1SNA195212R1000, type M6/8.STP, is a specialised screw-clamp test and disconnect terminal block designed for control, measurement and railway electrical circuits. Part of the Entrelec SNA screw-clamp range, it combines secure conductor termination with a convenient disconnect mechanism and integrated test access for efficient circuit isolation, commissioning and maintenance.

The M6/8.STP features a quarter-turn push-turn disconnect mechanism that simplifies circuit isolation and can be sealed in the open position where required. Two integrated 4 mm diameter test sockets provide convenient access for electrical measurements, allowing technicians to perform testing without disturbing the connected conductors.

With a 6 mm² rated cross-section, a rated voltage of 500 V and an 8 mm terminal spacing, the 1SNA195212R1000 is suited to demanding industrial and transportation installations. Its beige thermoplastic housing and compatibility with G32 and TH35 mounting rails make it a practical choice for modular control-panel and railway terminal assemblies.

Reliable Testing and Circuit Isolation

Test and disconnect terminal blocks provide technicians with a controlled way to isolate electrical circuits for commissioning, measurement and maintenance. The M6/8.STP incorporates a quarter-turn push-turn disconnect mechanism that allows the circuit to be opened without removing connected conductors, while the ability to seal the mechanism in its open position supports controlled maintenance procedures.

Two integrated 4 mm test sockets provide direct access for compatible test equipment, helping simplify electrical measurements and fault diagnosis. Combined with robust screw-clamp termination and compatibility with common industrial mounting rails, the M6/8.STP is particularly well suited to control, signalling, measurement and railway electrical installations.

Typical Applications

• Railway electrical and signalling systems.
• Industrial control and automation panels.
• Measurement and instrumentation circuits.
• Electrical testing and commissioning circuits.
• Control and auxiliary power systems.
• Machine control cabinets.
• DIN rail test and disconnect terminal assemblies.
