Feature → Amperage range 101–200 A provides targeted protection for medium‑power feeders. Business Impact → This enables precise coordination with upstream devices and reduces nuisance trips, extending equipment life and lowering maintenance costs. Application → Ideal for motor control centers and line feeders in manufacturing plants where predictable protection improves uptime and planning. Feature → Short-circuit rating of 200 kA is designed to withstand high fault currents without arcing. Business Impact → This enhances system reliability, minimizes damage to panels, and lowers the risk of cascading outages. Application → Suitable for distribution panels, large motors, and other high‑fault‑current environments. Feature → Voltage rating of 600 Vac and 600 Vdc supports both AC and DC protection within a single block. Business Impact → simplifies procurement, reduces parts diversity, and accelerates project timelines. Application → Works in mixed electrical installations, including DC drives and AC distribution networks. Feature → Three‑pole modular design with box lug terminals and wiring up to 250 kcmil Cu/Al (and #6‑250 kcmil Cu/Al). Business Impact → Provides robust, low‑impedance connections and straightforward field termination. Application → Ideal for high‑current bus connections in switchgear and motor control centers. Feature → Glass polyester construction delivers durable insulation and temperature performance in industrial environments. Business Impact → Enhances reliability in harsh facilities and reduces replacement cycles. Application → Suits panel-mounted protection inside factory floors, warehouses, and process plants. Feature → RoHS compliance plus UL Listed and CSA Certified marks. Business Impact → Supports regulatory alignment and simplifies audits, procurement, and supplier qualification. Application → Required by regulated facilities and multi-site deployments seeking traceable, standards‑based components.

FAQs
Designed for medium-power applications in industrial switchgear and motor control centers, the 1B0089-G1 handles 101–200 A with a 200 kAIC short-circuit rating, helping protect feeders, drive circuits, and distribution panels from overcurrent events while enabling reliable operation and easier maintenance in new builds or retrofit projects for improved uptime and reduced warranty risk.
With a 200 kAIC short‑circuit rating, the fuse block can interrupt large fault currents without arcing, protecting downstream equipment and reducing downtime. It also simplifies protective coordination with upstream devices, lowering the risk of cascading faults and extending the life of panels, drives, and feeders in demanding industrial environments.
Yes. The unit is rated at 600 Vac and 600 Vdc, allowing protection of both AC and DC circuits with a single modular block. This capability simplifies part selection and stocking, and when combined with a three‑pole design and box lug terminations, it supports clean field terminations for drives, inverters, and distribution panels.
The fuse block is UL Listed, CSA Certified, and RoHS Compliant, confirming safety, electrical performance, and environmental compliance. These certifications simplify procurement, enable regulatory approvals, and support traceability for multi-site deployments in manufacturing, energy, and process industries.
The Class T modular fuse block is a three-pole design with box lug terminals supporting 250 kcmil Copper or Aluminum conductors (Cu/Al) and #6-250 kcmil Cu/Al per phase. This enables robust, low‑impedance connections and straightforward field termination for high-current circuits in switchgear and motor control centers.
