FAQs
Install the 3-pole unit on a base-mounted rail or panel frame, connect lug terminals per the torque spec of 15–22 N·m, and ensure correct top-to-bottom terminal orientation. Use the included terminal bolt kit and verify Phase wiring follows the specified Top In - Bottom Out or Bottom In - Top Out arrangement for proper current flow.
Key ratings include 200 A per pole, 12 kV Rated Impulse Withstand Voltage, 1000 V Rated Insulation Voltage, and I_cm of 30 kA at 690 V. It is suitable for AC-21/22/23 currents with a 60 kW to 200 kW range depending on voltage, and a 3P configuration for main circuit isolation.
Yes. It carries a CE Declaration of Conformity and RoHS information, with CMRT documentation indicating responsible sourcing. This supports regulatory compliance in many regions and helps with green procurement programs.
Wide phase distance provides greater separation between conductors, improving creepage and clearance in high-voltage layouts. This reduces the risk of arcing and simplifies routing in larger busbar configurations, supporting safer installations in compact or retrofit panels.
The mechanism is rated for up to 20,000 mechanical operations, indicating long-term reliability. Plan for periodic torque checks on lug connections, ensure front-access operation during maintenance, and reference the data sheet for disassembly instructions to minimize downtime during servicing.
