The TE Connectivity 1SNK149011R0000 is an MC512PA pre-printed three-phase marker card designed for clear and consistent terminal identification in industrial electrical installations. Part of the ENTRELEC terminal marking range, this version features U1-U2-U3-V1-V2-V3-W1-W2-W3 (x10) plus U1 (x10) pre-printed markings in a horizontal orientation, providing a ready-made identification solution for three-phase motor and electrical terminal arrangements.
Manufactured from durable white polyamide, the MC512PA marker card provides professional, repeatable identification for panel builders, machine manufacturers and electrical installers. Its factory-applied alphanumeric markings help reduce manual labelling work while maintaining consistent and easy-to-read identification throughout terminal assemblies.
The 1SNK149011R0000 measures 12 mm high, 5.2 mm wide, 5 mm long and 4.8 mm deep, with a product weight of 10 g. It is specified for operating temperatures from -55 to +110 °C and has a UL 94V-2 flammability rating, supporting dependable use in demanding industrial environments.
Consistent terminal identification is particularly important in three-phase electrical and motor circuits, where U, V and W designations help engineers distinguish individual winding and connection points. The MC512PA 1SNK149011R0000 provides these commonly used alphanumeric designations in a factory-printed format, helping create orderly and easily traceable terminal assemblies.
By providing repeated U1, U2, U3, V1, V2, V3, W1, W2 and W3 identifiers on a single marker card, the 1SNK149011R0000 supports efficient panel construction, commissioning and maintenance. Its horizontal format is suited to applications where the marking needs to be read across the terminal arrangement.
