FAQs
The OT200U04C uses base mounting with screw terminals, featuring 20 mm terminal width for secure, high-current connections. The design requires separate handle and shaft components, and the front-facing IP20 protection makes it suitable for panel-mounted installations with straightforward maintenance access.
The 4P configuration allows simultaneous switching of all poles, ensuring synchronized transfer across phases, which reduces transient voltages and prevents intermediate unsafe states. This is ideal for motor control, power distribution panels, and systems requiring reliable source transfer under load.
Yes. The unit aligns with UL 98 and IEC 60947-6-1 standards, carries a CE declaration, and complies with RoHS directives. CMRT documentation is available for responsible sourcing, helping with supplier qualification and regulatory filings in regulated markets.
Plan for periodic inspection of screw terminations (tightening torque 15–22 N·m), proper alignment of the switch mechanism, and verification of the open transition position. The device has a rated mechanical durability of 8000 cycles, so spare handles/shafts and mounting hardware should be stocked for quick replacements.
It improves downtime readiness and asset reliability through high-current capability, robust mechanical life, and certified compliance. The UL/IEC approvals, RoHS/CMRT declarations, and easy installation contribute to reduced regulatory risk, lower maintenance costs, and faster time-to-production for automated lines.
