1sna230032r2500 – rc55 (201 a 300) horiz,

Why Choose the TE Connectivity 1SNA230032R2500 RC55 Marker Card?

The TE Connectivity 1SNA230032R2500 is an ENTRELEC RC55 pre-printed terminal block marker card designed for clear and systematic terminal identification in industrial electrical panels, control cabinets and automation systems. This version provides an ascending sequence from 201 to 300, giving 100 consecutive pre-printed numbers on a single marker card.

Designed with a horizontal orientation, the RC55 marker card allows panel builders and electrical engineers to identify terminal positions efficiently without individually printing each number. Its white marker surface provides clear visual contrast for the sequential numbering, supporting easier wiring, commissioning, fault finding and maintenance.

The 1SNA230032R2500 uses 5 mm markers and is manufactured from polyamide. The RC55 card has a weight of 2.70 g and carries a UL 94V-2 flammability rating, making it a practical identification accessory for compatible industrial terminal block assemblies.

Key Advantages

• Provides 100 ascending numbers from 201 to 300 on one marker card.
• Designed specifically for horizontal terminal block identification.
• 5 mm marker format for compatible terminal marking applications.
• White marker background provides clear contrast for easy number recognition.
• Pre-printed sequential format eliminates the need to produce numbers 201–300 individually.
• Polyamide construction with a UL 94V-2 flammability rating.

Key Features

• TE Connectivity ENTRELEC RC55 series.
• 201 → 300 ascending pre-printed sequence.
• 100 sequential markers per card.
• Horizontal product orientation.
• 5 mm marker length.

• UL 94V-2 flammability rating.

Reliable Sequential Terminal Identification

Sequential terminal numbering is an important part of creating organised electrical panels and easily traceable wiring systems. The TE Connectivity ENTRELEC RC55 system provides factory pre-printed markers that allow engineers to apply consistent identification without having to create each terminal number separately.

The 1SNA230032R2500 supplies the complete ascending sequence from 201 through 300 in a horizontal format. With 100 consecutive identifiers available on one card, it is particularly useful for larger terminal assemblies where structured numbering supports installation, circuit tracing, inspection and future maintenance.

Typical Applications

• Sequential industrial terminal block numbering.
• Electrical control panels and cabinets.
• PLC and industrial automation systems.
• Machine-building electrical assemblies.
• Switchgear and power distribution panels.
• Process control and instrumentation cabinets.
