TE Connectivity 1SNK149002R0000 MC512PA is a white polyamide vertical terminal block marker card pre-printed with the L1-L2-L3-N-PE sequence repeated 20 times for clear phase, neutral and protective earth identification.

The TE Connectivity 1SNK149002R0000 is a pre-printed MC512PA terminal block marker card designed for clear, standardised identification of electrical connections in industrial control panels and automation systems. Part of the TE Connectivity ENTRELEC terminal marking range, this version carries the sequence L1-L2-L3-N-PE repeated 20 times and uses a vertical marking orientation.
The combination of L1, L2, L3, N and PE markings provides a convenient identification solution for electrical circuits where phase conductors, neutral and protective earth connections need to be distinguished consistently. Factory pre-printing eliminates the need to create these commonly used designations individually, helping panel builders achieve neat, repeatable and easily recognisable terminal identification.
Manufactured from durable white polyamide, the 1SNK149002R0000 measures 12 mm high × 5.2 mm wide × 4.8 mm deep with a product length of 5 mm. It weighs 10 g, is specified for operating temperatures from -55 to +110 °C and carries a UL 94V-2 flammability rating, supporting dependable identification in demanding industrial environments.
Accurate terminal identification is essential for efficient installation, commissioning, maintenance and fault finding in industrial electrical systems. Using familiar L1, L2, L3, N and PE designations makes it easier for engineers and technicians to distinguish phase, neutral and protective earth connections throughout a panel.
The MC512PA 1SNK149002R0000 provides these five commonly used electrical designations as a repeated pre-printed sequence. With 20 repetitions of L1-L2-L3-N-PE, vertical orientation and durable polyamide construction, the card provides a practical way to create consistent identification across compatible terminal assemblies.
