Bussmann 16371-3 Eaton Series Three-Pole Power Distribution Block, 600V AC/DC, 310A

The Bussmann 16371-3 is an Eaton Bussmann series power distribution block engineered for reliable multi-circuit power distribution in industrial and commercial electrical systems. Rated 600 Vac and 600 Vdc at 310A, this three-pole power distribution block delivers a short-circuit current rating (SCCR) of 100 kA, making it well suited for demanding fault-current environments. Built with a black molded thermoplastic base and tin-plated aluminum connectors, the 16371-3 provides a durable, corrosion-resistant platform for splicing and distributing power within panelboards, control cabinets, motor control centers, and switchgear assemblies where dependable, high-amperage connections are essential.

Key Features

  • Electrical Rating: Rated 600 Vac and 600 Vdc at 310A for high-capacity power distribution across multiple circuits.
  • Three-Pole Configuration: Three-pole design allows simultaneous distribution of multiple conductors from a single incoming feed.
  • Short-Circuit Current Rating: SCCR of 100 kA provides robust protection against fault-current conditions in demanding industrial power systems.
  • Durable Base Construction: Black molded thermoplastic base resists heat, impact, and electrical stress for long-term reliability.
  • Tin-Plated Aluminum Connectors: Tin-plated aluminum connectors deliver reliable, corrosion-resistant terminations for consistent electrical performance over time.
  • Compact Distribution Block Design: Power distribution block format simplifies splicing and tapping of high-amperage conductors within a single, space-efficient component.

Bussmann 16371-3 – Frequently Asked Questions

1) Will a Bussmann 16371-3 distribution block work on a 480V three-phase feeder?
Yes. The 16371-3 is rated 600V AC and 600V DC, so a 480V three-phase circuit is well inside its rating, and the three-pole configuration handles all three phase legs in one block. At 480V you would size it against its 310A current rating.
2) Does the Bussmann 16371-3 have a high enough SCCR for an industrial control panel short-circuit current rating calculation?
The 16371-3 carries a 100 kA short-circuit current rating, so in most industrial control panels the distribution block will not be the limiting component in the assembly's SCCR calculation. The block is used in panelboards, control cabinets, motor control centers and switchgear assemblies.
3) Can I use aluminum conductors with the Bussmann 16371-3 power distribution block?
The connectors on the 16371-3 are tin-plated aluminum, which is the standard dual-rated bi-metal construction used for terminating either copper or aluminum conductors, and the tin plating is what resists corrosion at the termination. Confirm the conductor range marked on the block matches the cable size you are landing.
4) Is the Bussmann 16371-3 a fused block or just a splice and tap block?
It is an unfused power distribution block. The 16371-3 takes a single incoming feed and distributes it across multiple conductors on each of three poles; overcurrent protection has to come from a fuse block or breaker upstream. If you want the protection and the distribution in one device, you need a fused disconnect or fuse holder instead.
5) Can I use the Bussmann 16371-3 on a 600V DC solar or battery system, not just AC?
Yes, the rating covers both. The 16371-3 is rated 600 Vac and 600 Vdc, so it is usable on DC distribution up to 600V as well as AC branch and feeder taps, at up to 310A.
6) I only need to distribute a single phase - is the Bussmann 16371-3 the right block?
The Bussmann 16371-3 is built as a three-pole block, so a single-phase or single-conductor tap leaves two poles unused. Where a narrower pole count suits the panel better, the Square D Linergy 9080LB series is offered in one- through three-pole configurations, letting you match the pole count to the circuit. If the application is three-phase at 600V AC/DC and 310A, the 16371-3 covers all three legs in one component.
7) Is the base on the Bussmann 16371-3 open or insulated for finger-safe mounting?
The 16371-3 uses a black molded thermoplastic base that carries the connectors and resists heat, impact and electrical stress. The base material is what isolates the poles from each other and from the panel; it does not include a separate snap-on cover, so if your panel spec calls for finger-safe protection you will need the matching cover ordered separately.
8) What part number do I order for the three-pole 310A Bussmann distribution block?
Order Bussmann 16371-3. That is the manufacturer part number for the Eaton Bussmann series three-pole block rated 600V AC/DC at 310A. There is one configuration, so there are no finish or pole-count options to specify.
