TE Connectivity SNA Series — Screw, Spring Clamp and Stud Terminal Blocks | ENTRELEC Terminal Block Family:

The ABB screw clamp technology is designed to avoid accidental releases due to vibrations, shocks or even abusive cable draw. Our exclusive design minimizes the needs of retightening campaigns. The screw clamp technology can fit up to two conductors per clamp which offers extended possibilities in electrical cabinets.The SNA Series is a large scope of power terminal blocks dedicated to the connection and distribution of power into electrical installations. Power terminals blocks features standard stud-stud connections as well as hybrid terminals (stud-screw clamp).

The SNA Screw Clamp terminal blocks benefit from 50 years of experience and offer a large choice of sections, colour variants and mountings. SNA Stud technology terminal blocks are dedicated to the connection and distribution of power into installations. The well known historical range is available in screw clamp and stud technologies with a large choice of sections and colour variants. Qualified for standard and power applications up to 300 mm2 (1000 kcmil).

SNA Series Features:

Available functions : feed-through, ground, disconnect, fuse, single to triple deck, test & measurement

Reliable hardened steel clamp

10 pre-assembled blocks for quick mounting

SNA Stud Terminal Block Features:

Saved space in cabinets thanks to high density wiring with up to two conductors per stud

Increase operator security thanks to rotating and removable protective covers for jumpers and connections

Secured wiring thanks to the combination of lug and stud that prevent conductor pull-out

Reduce maintenance operations : our clamps include vibration resistant washers combined with highly resistant steel clamps

Assemby is facilitated and mounting time is reduced thanks to bi-stable foot that allows fast locking or removal of terminal block on rail

Allow installation flexibility with extra mounting options such panel or plate

Connecting capacity from 35 to 300 mm² (1 AWG to 1000kcmil)

Technologies : stud-stud or hybrid stud-screw terminal blocks

Compatible with lugs in acordance with NF C 20-130 and DIN 46234

Connections and jumpering system are isolated (IP20) thanks to rotative protective covers

Pins allow terminal blocks to be snapped together for better stability

Derivation accessory for monitoring relays
