Milbank U4373-XT-5T9-AMS – Frequently Asked Questions

1) What is a 5-terminal ringless lever bypass breaker used for?
A 5-terminal ringless lever bypass allows safe breaker maintenance without power interruption. The bypass position routes current around the breaker during service. The 5th terminal provides additional grounding or neutral connection options.
2) What does the 3-position operation include?
The three positions are: Normal (breaker in service), Off (power disconnected), and Bypass (current flows around breaker for maintenance). The lever mechanism provides clear visual indication of each position.
3) Why is the 5th terminal at 9 o'clock position significant?
The 9 o'clock positioning provides optimal access for additional connections while maintaining proper spacing from main terminals. This configuration meets Ameren utility specifications for their applications.
4) What are the 2 large closing plates for?
Large closing plates provide enhanced contact surface area for high-amperage applications. They ensure reliable connection and help distribute heat across a larger area during operation.
5) Is this compatible with 200-ampere circuit breakers?
Yes, this unit includes breaker provision specifically designed for 3-pole, 200-ampere breakers. Verify your specific breaker model compatibility with manufacturer documentation before installation.
6) What does "ringless" mean in this application?
Ringless terminals accept direct wire connection without requiring ring lugs or terminals. This simplifies installation and reduces connection points that could create resistance or failure points.
7) What electrical codes apply to lever bypass installations?
Follow NEC Article 230 for service equipment and local electrical codes. Utility specifications like Ameren requirements also apply. Always obtain proper permits and inspections for service equipment installations.
8) What mounting requirements should I consider?
Verify enclosure dimensions accommodate the unit and breaker. Check manufacturer mounting template for exact requirements. Ensure adequate clearances for lever operation and maintenance access.
9) How do you safely operate the bypass function?
Follow lockout/tagout procedures. Move lever to bypass position before breaker removal. Verify bypass operation with appropriate test equipment. Never operate under load without proper safety precautions.
10) What maintenance does a lever bypass require?
Inspect connections annually for tightness and corrosion. Check lever mechanism for smooth operation. Clean contact surfaces as needed. Schedule utility coordination for any maintenance requiring bypass operation.
11) Are there related bypass configurations available?
Various terminal counts and amperage ratings are available. Check our electrical equipment section for other bypass switch options and compatible breakers for your application.
