Overview
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:
Connecting capacity from 0.2 to 300 mm2 (22 AWG to 1000 kcmil)
Technologies: screw clamp, stud
Available functions : feed-through, ground, disconnect, fuse, single to triple deck, test & measurement
Power stud range available with stud-stud or stud-screw clamp technologies
Ease the identification of functions inside cabinet thanks to large range of coloured variants
The SNA connection technologies (screw clamp, and stud) eliminate the need for retightening campaigns thanks dedicated anti-release system
Avoid mounting and wiring errors thanks to asymmetrical design
Allow installation flexibility with extra mounting options such as TS32 rail,panel or plate
50% faster assembly time thanks to the locking pin : 10 pre-assembled blocks plugged-in on rail at a time
Elimination of faulty manouvers thanks to screw type jumper bars
SNA Screw Clamp Terminal Block Features:
Save on maintenance & trouble shooting time thanks to our anti-release system. Screw is locked in total safety
Enhanced reliability and reduce the maintenance on installations thanks to clamp high torque protection
Avoid mounting and wiring errors thanks to asymmetrical design
Allow installation flexibility with extra mounting options such as TS32 rail
50% faster assembly time thanks to pre-assembled blocks
Elimination of faulty manouvers thanks to screw type jumper bars
Connecting capacity from 0.2 to 240 mm2
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
