Terminal blade Rittal AS 4050.723 — steel contact blade for electrical enclosure terminals

Rittal AS 4050.723 is a steel terminal/contact blade designed for use in electrical enclosures and terminal blocks. Manufactured from conductive steel, this contact blade provides a rigid and durable connection point for conductor insertion, bridging of terminal points, and reliable current transfer within industrial control cabinets and wiring assemblies. The product is intended for applications where a solid metal contact with consistent mechanical and electrical properties is required.

Advantages

The steel construction offers mechanical strength and wear resistance, ensuring stable contact under repeated insertion and fastening. As a metallic contact blade, it provides low electrical resistance and good conductivity for signal and power connections. The compact form factor makes it compatible with standard terminal block arrangements and allows straightforward replacement or retrofitting in existing enclosure setups.

Suitable for

• Electrical enclosure terminal blocks in industrial control cabinets
• Bridging or linking adjacent terminals for common potentials
• Wiring assemblies where a durable metal contact is required
• Replacement of worn or damaged contact blades in terminal strips

When it may not be suitable

This steel contact blade is not intended for direct exposure to corrosive environments without additional protective measures; prolonged moisture or chemical exposure may lead to corrosion. It may also be unsuitable for applications that require specialized plated contacts for extremely low contact resistance or for use with non-standard terminal geometries where mechanical fit cannot be guaranteed.

Key specifications

• Material: Steel conductive contact blade
• Function: Terminal contact/bridge for electrical terminals
• Typical use environment: Industrial control cabinets, wiring assemblies
• Form factor: Compact blade designed for insertion into terminal blocks

How to use

Install the blade by inserting it into the matching terminal slot or receptacle inside the electrical enclosure, ensuring correct orientation and full seating for reliable contact. Where required, secure the terminal connection according to the terminal block's fastening method (screw, clamp or similar) and verify electrical continuity with appropriate test equipment. Replace or remove the blade only with power removed and following standard lock-out/tag-out and electrical safety procedures.

What to consider before purchase

• Confirm mechanical compatibility with your terminal block type and slot dimensions
• Assess environmental conditions for potential corrosion and plan protective measures if needed
• Verify required electrical conductivity and whether plated or alternative contacts are necessary
• Ensure the blade's form factor fits your enclosure and allows proper fastening

Usage recommendations

Use the steel contact blade in dry, ventilated enclosure interiors or with appropriate corrosion protection in humid or chemically active environments. Always de-energize circuits before installation or replacement and perform continuity checks after installation to confirm secure contact. For applications requiring the lowest possible contact resistance or enhanced corrosion resistance, consider specifying plated or specialty contacts compatible with your terminal system.
