June 11, 2025 - Altech Corporation , a leader in industrial automation solutions, announces the release of its ATEX-IECEx approved terminal blocks, which are designed to provide greater safety and reliability in potentially explosive atmospheres. This extensive offering includes multiple connection technologies, providing versatile solutions for diverse industrial applications.
Technical features
The ATEX-IECEx Directive considers both electrical sources of explosion and potentially explosive concentrations of gas, vapor, mist and dust in the air. Altech’s ATEX-IECEx approved terminal blocks are designed for use in ATEX/IECEx certified enclosures with a minimum IP54 rating. Key specifications include:
- Temperature ranges: Terminal blocks feature a maximum service temperature of 110°C, with an ambient temperature range of -60° to +66°C at mounting position.
- Insulation material: Polyamide 66, CTI 600 / Material Group 1.
- Wire sizes: Wire sizes range from 24AWG up to 250kcmil, depending on the model.
- Marking: Altech Terminal Blocks with ATEX-IECEx approval are marked accordingly.
For some models, the ambient temperature range is -40° to +40°C, with a service temperature range of -40° to +85°C.
For increased safety (“e”): Ex eb IIC Gb. Some are marked Ex ec IIC Gc, signifying robust construction to prevent ignition sources for hazardous gas environments. For intrinsic safety (“i”): Ex ib IIC Gb. Some are also marked Ex ic IIC Gc, indicating the circuit’s electrical and thermal energy is restricted to levels insufficient to cause ignition in an explosive atmosphere.
Diverse product offerings
Altech’s ATEX-IECEx approved line includes various terminal block technologies to meet diverse application requirements. Specific products include:
- CP Series Push-In Terminal Blocks with tool-less connection technology, a stainless steel push-in spring and universal push-in jumper system.
