1snl317510r0000 – dbl 175 distribution block single pole

Why Choose the TE Connectivity DBL175 Single-Pole Power Distribution Block?

The TE Connectivity DBL175 (1SNL317510R0000) is a compact, high-current single-pole power distribution block designed for efficient distribution of electrical power within industrial control panels, switchgear and machinery. Part of the TE Connectivity ENTRELEC DBL series, it combines screw-clamp connection technology with a modular format for reliable high-current power distribution.

The DBL175 provides 12 connection positions within a single-pole, single-circuit configuration, allowing an incoming power supply to be distributed across multiple outgoing conductors. Its two-input design also provides flexibility for expanding the number of outputs by linking compatible DBL blocks or for using two incoming conductors where the installation design and applicable ratings permit.

With a rated current of 175 A according to IEC and UL specifications, IEC voltage ratings of 1000 V AC and 1500 V DC, and a 100 kA short-circuit current rating, the DBL175 is engineered for demanding industrial power distribution. DIN rail or plate mounting options and its compact design can also reduce installation time and panel space compared with conventional copper-bar distribution arrangements.

Flexible High-Current Distribution for Industrial Panels

Power distribution blocks provide an organised method of dividing an incoming electrical supply between multiple outgoing conductors. The DBL175 incorporates 12 connections within a single-pole assembly, including two input connection positions and ten output connection positions, providing substantial wiring flexibility without the complexity of a conventional fabricated copper-bar distribution system.

The DBL175 can be installed on DIN rail or directly onto a mounting plate and is designed to help reduce assembly time and occupied panel space. Its two-input arrangement can also be used to increase distribution flexibility: compatible DBL blocks can be interconnected to provide additional outputs, while suitable dual-conductor arrangements can support higher-current configurations when installed in accordance with the manufacturer's specified conductor sizes and ratings.

Typical Applications

• Industrial control panels and switchgear assemblies.
• Main and branch power distribution circuits.
• Machine building and OEM electrical systems.
• Automation and process control cabinets.
• High-current distribution within manufacturing equipment.
• DIN rail and plate-mounted electrical distribution assemblies.
