Why Choose the TE Connectivity 1SNL312510R0000 DBL125 Distribution Block?
The TE Connectivity 1SNL312510R0000, also identified as DBL125, is a compact single-pole power distribution block designed for efficient distribution of electrical power within industrial control panels, machinery and electrical cabinets. Part of the TE Connectivity ENTRELEC DBL series, it combines high-current capability with screw-clamp connections and a space-efficient DIN rail-mounted format.
The DBL125 provides eight connection positions in a single-pole configuration, enabling one incoming supply to be distributed to multiple outgoing conductors from a compact assembly. Its screw connection technology provides secure conductor termination, while the grey polyamide housing and modular design help simplify installation and maintain an organised panel layout.
With a rated current of 125 A under IEC specifications and 115 A under UL specifications, the DBL125 supports demanding industrial power distribution applications. It is rated up to 1000 V AC and 1500 V DC under IEC specifications and accommodates main-circuit copper conductors up to 35 mm².

Compact High-Current Power Distribution
Power distribution blocks provide an efficient method of splitting an incoming electrical supply into multiple outgoing circuits from a common connection point. This approach can reduce the number of individual terminal blocks and interconnecting conductors required, helping create cleaner and more space-efficient electrical panel assemblies.
The DBL125 is designed for direct mounting on standard 35 mm DIN rail and combines one main circuit with multiple output connections. Its 125 A IEC rating and conductor capacity up to 35 mm² make it well suited to power distribution within machinery, automation systems, switchgear and industrial control cabinets.
Typical Applications
- Industrial electrical control panels.
- Power distribution and branch circuits.
- Machine building and automation systems.
- Switchgear and distribution cabinets.
- DIN rail electrical assemblies.
- OEM equipment and panel building.
