RUKO STB-180°-M5-S-m Test Plug Socket for CT Secondary Circuits

Test plug socket for current transformer secondary circuits, featuring a straight 180° conductor entry and M5 screw connection for secure, tool-free testing.

Advantages

The STB-180°-M5-S-m is engineered for reliable CT secondary circuit testing. Its M5 screw connection ensures a stable, low-resistance contact, while the straight 180° entry simplifies wiring in tight spaces. Constructed from grey polyamide (PA 66) with a UL 94 V-0 flammability rating, it withstands harsh industrial environments and operating temperatures from -35 to +105 °C.

Suitable for

• Testing current transformer secondary circuits in electrical panels
• Use with WAGO 209 Series CT disconnect terminal blocks
• Industrial control and power distribution systems requiring safe isolation for testing
