Allen-Bradley HFD3020L Brand Introduction
Allen-Bradley HFD3020L is HFD series 3-pole molded case circuit breaker developed by Rockwell Automation for low voltage power distribution overload and short-circuit protection. It specializes in cutting off fault current for power circuits, serving as thermal-magnetic protection assembly for MCC motor control centers and industrial power cabinets. Molded Case Circuit Breaker is the core unit of Allen-Bradley HFD3020L. Molded Case Circuit Breaker adopts rear chassis mounting structure for power distribution enclosures. Molded Case Circuit Breaker supports 3-pole 20A rated current with thermal-magnetic trip function. Molded Case Circuit Breaker realizes circuit automatic disconnection under overload and short-circuit fault conditions. Allen-Bradley HFD3020L provides stable Drive for workshop field low voltage power circuit protection control. Drive supports max 600VAC operating voltage. Drive has fixed thermal overload and instantaneous magnetic short-circuit trip protection. Drive features high interrupting capacity for heavy industrial power distribution occasions. Allen-Bradley HFD3020L features reliable Transmission for upstream power supply and downstream load devices. Transmission communicates via copper power wiring loop. Transmission is fully compatible with CENTERLINE 2100 motor control centers and low voltage distribution systems. Transmission delivers fast fault cut-off signals to protect field power loads. Allen-Bradley HFD3020L is widely used in motor control center, fan pump power supply, machine tool power distribution and legacy power protection system renovation. With mature Rockwell molded case breaker technology, this circuit breaker works within temperature range 0~60℃ and has strong anti-vibration performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted HFD series 3-pole molded case circuit breaker solution.
