FAQs
This model ships without terminals, auxiliary contacts, or metric load and line end caps, so you’ll need compatible terminations and accessories. Ensure a three-pole LG-frame fit, verify 400 A rating, and select appropriate line/load terminals and optional UVR if required. Check alignment with Digitrip 310 settings for proper coordination and fault clearing times.
Key ratings include 400 A nominal current, 65 kAIC interrupt rating at 240 VAC, and 50–60 Hz operation. It also supports 480 VAC and 600 VAC fault levels with respective lower interrupt ratings. This makes it suitable for typical industrial feeders and motor circuits while maintaining coordination with upstream protections.
Yes. With three poles, LG frame compatibility, and 400 A capacity, this MCCB is well-suited for motor feeders and machine control panels. The Digitrip 310 electronic trip provides precise coordination and fast fault clearance, helping reduce motor damage and downtime in production environments.
The unit is IEC rated, UL Listed, CSA Certified, and CE marked. These certifications support global deployment, meet safety and performance standards, and facilitate regulatory compliance for multinational plants and projects.
The robust 65 kAIC at 240 VAC rating supports long-term protection for high-energy faults, reducing maintenance costs by limiting downstream damage. The electronic Digitrip 310 enables precise fault drafting and predictable replacement planning, while the compact LG-frame size simplifies future panel upgrades or retrofits.
