TE Connectivity 1SNA400184R2700 MA2.5/5 red feed-through screw clamp terminal block with 5 mm spacing, 2.5 mm² rated cross-section, 24 A IEC rated current and 1000 V IEC rated voltage.
Why Choose the TE Connectivity 1SNA400184R2700 MA2.5/5 Red Terminal Block?
The TE Connectivity 1SNA400184R2700 is a compact MA2.5/5 feed-through screw clamp terminal block from the ENTRELEC SNA series, designed to provide reliable conductor connections in industrial control panels, automation systems and electrical enclosures. Its single-level construction and compact 5 mm spacing make it suitable for high-density DIN rail installations.
The terminal block supports 2.5 mm² flexible conductors and rigid stranded conductors up to 4 mm², with a rated current of 24 A and an IEC rated voltage of 1000 V. The screw terminal connection provides a secure and straightforward method of terminating industrial wiring.
The MA2.5/5 features a distinctive red housing and mounts directly onto G32, TH35-7.5 and TH35-15 DIN rails. Its polyamide 6.6 insulating body, IP20 protection and UL94 V-0 flammability rating make it suitable for professional control-panel and industrial electrical installations.
