FAQs
The RDF400J-2 is designed to provide safe, reliable isolation for electrical circuits within industrial panels and motor feeder assemblies. Its fused rotary design supports rapid de-energization during maintenance, minimizing exposure to live circuits while allowing service personnel to work with confidence. This makes it well-suited for control cabinets and protection schemes that require dependable disconnection with clear visual status.
The RDF400J-2 is rated for 400A with a voltage range of 600 Vac and 250 Vdc. These ratings support heavy-duty circuit protection and isolation for high-current equipment, enabling safe shutdown and maintenance across AC mains and DC circuits commonly found in industrial applications such as motors, drives, and feeders.
Yes, RDF400J-2 is RoHS compliant. This means the switch meets environmental standards limiting hazardous substances in electrical components, facilitating regulatory compliance and greener procurement. While the spec sheet does not list additional certifications like CE or SIL, RoHS compliance supports modern factory and panel builds that prioritize sustainable materials alongside robust electrical performance.
Install RDF400J-2 by aligning it to available mounting space within the enclosure, using its front/side handle for manual operation during energization checks. With its 7 in width, 15.5 in height, and 1 in depth, plan for adequate clearance and wiring space. Verify the wiring conforms to 600 Vac / 250 Vdc ratings and ensure proper PPE during maintenance due to live circuits.
The fused rotary disconnect switch relies on reliable mechanical operation and intact electrical contacts. Regular visual inspection for corrosion, secure mounting, and verification of actuator movement help prevent unexpected outages. Its RoHS compliance reduces regulatory risk, while the robust rating supports longer replacement intervals in demanding environments, contributing to lower lifecycle costs and improved device uptime.
