Special features
Non-interchangeable trip
Feature → Business Impact → Application: The FLB220 TT20 1 uses a 20 A thermal-magnetic mechanism in a TEB frame to provide fast, predictable tripping curves that limit fault currents, safeguarding downstream equipment and reducing unplanned outages in hazardous environments. This translates to improved panel uptime and lower maintenance costs for critical lines such as conveyors, pumps, and press controls in plants handling flammable or volatile substances. Application: ideal for explosion-proof control panels in chemical, oil & gas, and mining sites where NEC/CEC compliance and robust protection are mandatory. Feature → Business Impact → Application: Copper-free aluminum enclosure with threaded cover delivers excellent corrosion resistance and a secure enclosure seal, extending service life in harsh environments and simplifying field retrofits. Application: suitable for outdoor or damp locations common in processing facilities and metalworking shops. Feature → Business Impact → Application: Single-pole, 3/4" trade size with non-interchangeable trip reduces misconfiguration risk and ensures consistent protection settings across assemblies. Application: preferred for standardized control panels and modular rack setups in hazardous areas. Feature → Business Impact → Application: 120 Vac/125 Vdc voltage rating and 6.25 in depth with 10.25 in height and 7 in width enable compact, easy-to-install integration in tight electrical rooms. Application: used in compact switchgear and small-distribution panels where space is at a premium. Feature → Business Impact → Application: NEC/CEC certification, area classifications, and NEMA ratings 3, 4, 7, 9 provide clear compliance, enabling faster project approvals and reducing third-party testing time. Application: essential for regulated facilities and cross-border deployments. Feature → Business Impact → Application: Non-interchangeable trip feature minimizes human error during maintenance, protecting against accidental reconfiguration and elevating overall system reliability. Application: critical in batch processing lines and safety-critical automation loops where uptime is paramount.
