FAQs
Install by mounting the unit in a suitable enclosure, align with three-pole terminations, and connect conductors to the tin-plated aluminum terminals. Use the molded thermoplastic base for insulation and short-circuit containment. Always follow the manufacturer’s torque specs and refer to the Eaton 16373-3 datasheet during layout to ensure proper clearance and secure termination.
The 16373-3 is rated for 600 Vac and 600 Vdc with a 310 A capacity and SCCR of 10 kAIC, enabling safe power distribution for both AC and DC buses in industrial controls. Its three-pole design supports balanced phase distribution, while the molded base and tin-plated connectors provide reliable insulation and corrosion resistance in challenging environments.
This block is well-suited for industrial control panels, motor control centers, and machine-build enclosures where high-current, three-phase distribution is needed. Its compact footprint and robust construction support efficient panel layouts, quicker wiring, and easier maintenance within automation and process control environments.
The 16373-3 carries RoHS compliance and data suggests UL-recognized documentation from Eaton's datasheets. For CE or additional third-party certifications, consult the factory. The block also features a high SCCR of 10 kAIC, which supports safe operation in demanding industrial applications.
The combination of a three-pole design, 310 A rating, and 10 kAIC SCCR reduces wiring errors and protective-device coordination complexity, lowering commissioning time and maintenance costs. The tin-plated aluminum terminations improve durability, while RoHS compliance simplifies sourcing, contributing to lower total cost of ownership in automation projects.
