The TMF 45-500 designation indicates a thermal-magnetic fixed trip unit with a current rating range of 45 to 500 A, and the 3P means three-pole construction. The UL/CSA suffix confirms it carries North American safety certifications for panelboard and switchboard applications. The 45–500 A range means the breaker can be adjusted or ordered with a specific fixed rating within that band — critical for coordinating with downstream loads and upstream feeders. The 3-pole construction suits three-phase power distribution in industrial control panels, switchboards, and motor control centers. ## Deployment Context This MCCB is designed for panel-mount installation in distribution boards and switchgear assemblies. The UL/CSA listing means it meets North American code requirements for branch circuit protection in commercial and industrial installations. It is not a DIN-rail device — it bolts into a panel via its own mounting base.","metaTitle":"ABB XT1HU3045AYD000XXX NEXT1H 125 TMF 45-500 3P F F UL/CSA","metaDescription":"ABB XT1HU3045AYD000XXX NEXT1H 125 TMF 45-500 3P F F UL/CSA molded case circuit breaker.
