The TE Connectivity 1SNA115229R2000, designated M4/6.SNTS, is an ENTRELEC SNA disconnect terminal block with a spring-loaded screw-clamp design for industrial signal and current-transformer circuits. Its integrated disconnect function and test socket provide a practical way to isolate, test and maintain circuits within DIN rail-mounted electrical assemblies.
Designed with a rated conductor cross-section of 4 mm², the M4/6.SNTS carries an IEC rated current of 10 A at up to 500 V AC. The screw terminals accept rigid and flexible conductors from 0.5–4 mm², providing a versatile connection range for industrial control and instrumentation wiring.
The M4/6.SNTS occupies only 6 mm of DIN rail space and has a grey and orange polyamide housing. With an IP20 protection rating, UL 94 V-0 flammability classification and operating temperature range from -55 to +110 °C, it is engineered for dependable service in professional electrical panels and demanding industrial environments.
Disconnect terminal blocks allow technicians to isolate a circuit without removing its field wiring, making testing, commissioning and maintenance more efficient. The M4/6.SNTS incorporates a disconnect function together with a test socket, making it particularly useful for signal and measurement circuits where controlled isolation and convenient test access are required.
The spring-loaded screw-clamp arrangement helps maintain contact pressure even if the screw clamp becomes loose. Combined with the compact 6 mm profile and compatibility with widely used DIN rail formats, this makes the M4/6.SNTS a practical terminal for industrial control panels, energy applications and current-transformer circuit assemblies.
