FAQs
Yes. The FNM-12 uses ferrule-end x ferrule-end connections, designed for straightforward installation in standard control panels and distribution boards. Its 250 V rating and 12 A nominal current make it a drop-in option for Bussmann series assemblies, while nickel-plated endcaps help ensure durable contact surfaces in demanding environments.
Key specifications include a 12 A amperage rating, a 10 kAIC interrupt rating at 250 V, and a ferrule-terminal connection scheme. It is CE Marked and RoHS compliant, with a time-delay (or slow-blow) characteristic suitable for inrush currents typical of motors and power supplies in automation panels.
Ideal for control circuits, motor protection, and power distribution within automation environments. The time-delay action helps manage startup surges, while the high interrupt rating provides robust protection for feeders. Suitable for replacement in existing Bussmann series deployments and for new panel builds requiring reliable overcurrent protection at 250 V.
The FNM-12 is CE Marked and RoHS compliant, indicating conformance with European safety and environmental requirements. Its 250 V rating and 12 A capacity align with common industrial protection standards, while the non-indicating design supports straightforward status indication in many panel configurations.
Nickel-plated bronze endcaps and a robust dual-element design contribute to durability and longer service life in harsh environments, reducing replacement frequency. The time-delay feature minimizes nuisance trips, improving uptime and reducing maintenance costs. Standard packaging and compatibility with ferrule-term wiring further streamline stocking, procurement, and field service efficiency.
