Overview

The Willele MRK DIN rail terminal block is engineered for safe, tidy wiring in industrial control panels.
This DIN rail terminal block combines a flame-retardant nylon housing with high-conductivity copper conductors to deliver reliable connections, clear circuit identification and low maintenance.

Covering wire cross-sections from 2.5 mm² to 120 mm², the MRK series supports 750 V / 1000 V classes and 24 A – 269 A current ratings.
A 35 mm snap-on mount speeds installation, making this DIN rail terminal block a practical choice for new builds and retrofits alike.

Cross-Section: 2.5 mm² – 120 mm²

Voltage Class: 750 V / 1000 V

Current Range: 24 A – 269 A
