MA2.5/5 Entrelec Grey Feedthrough Terminal 2.5mm² 1SNA115486R0300

The MA2.5/5 (alternate code 1SNA115486R0300) is a grey feedthrough terminal block manufactured by TE Connectivity (Entrelec), rated at 24A and 1000V with a 2.5mm² screw clamp connection.

The Entrelec MA2.5/5 is a compact, single-level feedthrough terminal block designed for reliable conductor connection in electrical control panels and industrial installations. Built on proven screw clamp technology with over 50 years of development behind it, it offers a secure, vibration-resistant connection that minimises the need for retightening. Its slim 5mm pitch makes it ideal for high-density rail assemblies.

Key Features

• 24A / 1000V Rating: Suitable for a wide range of industrial control and power circuits without over-specifying.
• Screw Clamp Connection: TE Connectivity's anti-release design locks the screw securely, resisting vibration and accidental loosening in demanding environments.
• Flexible Cable Compatibility: Accepts rigid conductors from 0.2–4mm² and flexible conductors from 0.22–2.5mm², covering most standard wiring requirements.
• Universal Rail Mounting: Snaps onto G32, TH35-7.5, and TH35-15 DIN rails — both symmetrical and asymmetrical — for maximum installation flexibility.
• 5mm Pitch Spacing: Compact footprint enables high-density terminal arrangements within the panel, saving valuable cabinet space.
• IP20 Protection: Provides finger protection against accidental contact with live parts, meeting IEC 60529 requirements.
• Polyamide 6.6 Insulation (UL 94V-0): Flame-retardant housing material ensures safety and compliance in fire-risk environments.
• Colour-Coded Options Available: The grey MA2.5/5 is part of a range available in multiple colours, allowing quick visual identification of circuit functions.

Applications

The MA2.5/5 is widely used in industrial control panels, machine building, process automation, and electrical distribution boards.
