Product Description

• The Weidmuller ZTR 2.5/O.TNHE is a Z-Series test-disconnect terminal block designed for industrial electrical control panels, instrumentation systems, and electrical distribution applications requiring accessible circuit testing and isolation.
• Each terminal block features two tension-clamp conductor connection points and an integrated test-disconnect arrangement, allowing the circuit connection to be interrupted for compatible testing and maintenance procedures.
• The spring-clamp connection technology provides reliable conductor retention without conventional screw-tightened wire terminals, supporting efficient electrical panel installation and maintenance.
• Designed for standard TS 35 DIN rail mounting, these terminal blocks feature a compact 5.1 mm width and compatibility with plug-in cross-connectors for organized circuit distribution.
• The ZTR 2.5/O.TNHE supports a nominal conductor cross-section of 2.5 mm² and features manufacturer-specified IEC ratings of 500 V and 20 A. Its conductor clamping range extends from 0.05 mm² to 4 mm², depending on conductor type and termination method.
• The dark beige insulating housing is manufactured from Weidmuller's WEMID material and features a UL 94 V-0 flammability classification.
• The terminal block incorporates a test connection and a disconnecting arrangement for electrical testing applications. It is not a fuse terminal block and does not provide overcurrent protection.
• These terminals are suitable for industrial automation, instrumentation wiring, control cabinet assemblies, electrical distribution systems, and compatible marine electrical installations.
