1sna356210r2100 – brt175a distribution block
TE Connectivity BRT175A 1SNA356210R2100 is a three-pole screw-clamp distribution block with seven connections per pole, up to 175 A copper-conductor capability, a 50 mm² rated cross-section and a 100 kA short-circuit current rating.
Why Choose the TE Connectivity BRT175A Distribution Block?
The TE Connectivity / Entrelec BRT175A, part number 1SNA356210R2100, is a heavy-duty three-pole distribution terminal block designed to distribute high-current incoming power to multiple outgoing circuits. Also documented under the extended designation BRT175AL, it combines three independent distribution paths within a single compact assembly for industrial switchgear, machinery and control-panel applications.
The BRT175A provides three poles with seven connections per pole, comprising one main incoming connection and six outgoing connections. It supports copper conductors with a maximum current of 175 A and conductor sizes up to 70 mm², while the outgoing connections accommodate conductors up to 16 mm².
With voltage capability up to 1000 V AC / 1500 V DC under applicable IEC data and 600 V under UL specifications, the BRT175A is designed for demanding distribution duties. Its screw-clamp connections, 100 kA SCCR and compatibility with TH 35-7.5 and TH 35-15 DIN rails provide a robust and installation-friendly solution for professional power distribution.

High-Current Three-Phase Power Distribution
The BRT175A consolidates three independent power-distribution circuits into one compact terminal assembly. Each pole provides a large incoming screw-clamp connection and six outgoing connections, allowing a substantial incoming conductor to supply multiple downstream circuits without the need to construct a distribution arrangement from numerous separate terminal blocks.
Its 175 A copper-conductor capability, main conductor capacity up to 70 mm² and 100 kA SCCR make the BRT175A particularly suitable for demanding industrial distribution systems. Standard 35 mm DIN rail mounting and screw-clamp terminations also support efficient installation, maintenance and circuit organisation within electrical cabinets.
Typical Applications
- Three-phase industrial power distribution.
- Electrical switchboards and distribution panels.
- Industrial control cabinets.
- Motor control centres and machinery panels.
- Factory automation systems.
- High-current branch circuit distribution.
- Power distribution to multiple downstream loads.
- OEM machinery and electrical panel construction.
