Entrelec MA Series 1-Level Fused DIN Rail Terminal Block Grey, 4mm² and 6mm² Cable, Screw Termination, 630V 1SNA115657R2500

Entrelec 1SNA115657R2500 MA Series fused DIN rail terminal block is engineered to deliver reliable electrical protection and connectivity for industrial, commercial, and manufacturing electrical setups. This 1-level fused terminal is finished in grey, manufactured using robust polyamide 6.6 that offers excellent flame resistance and mechanical strength, suitable for demanding operational environments.

Designed for wiring cable cross-sections of 4mm² to 6mm² and wire sizes ranging from 14 AWG to 12 AWG, this terminal supports a maximum operating voltage of 630 volts and a nominal current rating of 6.3 amps. The screw termination allows secure wire clamping with hardened captive screws that prevent burring, ensuring both safety and longevity.

The terminal block’s 8mm pitch fits standard DIN rail profiles including asymmetric 'G' profile and top hat rail profiles, providing versatile mounting options for modular industrial control panels. It incorporates a lever action fuse carrier that accepts both 20x5mm and 25x5mm fuses, delivering flexible protection options. The fuse failed indication options (LED or neon indicators) are available in other variants, enhancing maintenance efficiency.

This product operates reliably within a wide temperature range from -55°C to 110°C, making it fit for use in various industrial environments including electrical distribution, manufacturing, automation, and HVAC systems. It carries critical certifications such as CE, CSA, EAC and compliance with EU Directive 2002/95/EC, reinforcing its adherence to global safety and environmental standards.
