Frequently Asked Questions
Q: What is the maximum motor power this contactor can handle?
A: The LC1N3201Q5N can control three-phase motors up to 15kW at 400V AC in AC-3 duty. For higher power applications, consider larger contactors from the Schneider Electric range available at KoeedMRO contactors.
Q: Can this contactor be used for DC motor applications?
A: No, this contactor is specifically designed for AC applications only. For DC motor control, you would need specialized DC contactors with appropriate arc suppression capabilities.
Q: What overload protection is recommended with this contactor?
A> Always use appropriate thermal overload relays such as Schneider Electric LRD series to protect your motor from overload conditions. The complete motor starter combination ensures both control and protection functions.
