I.Product Overview
Brand and Positioning
Brand:Cuttler Hammer(now part of Eaton’s electrical business unit),a leading global provider of power management and distribution solutions.
Positioning:Industrial-grade low-voltage electrical components,potentially used in power distribution system protection,motor control,or power switching applications.
Model Description
2D78559G01:
2D:May indicate a product series(e.g.,2D series circuit breakers or contactors).
78559:Function code or specification identifier(e.g.,rated current,number of poles,breaking capacity).
G01:Version number or configuration variant(e.g.,auxiliary contact type,mounting method).
II.Core Functions and Applications
Speculated Functionality(to be verified in actual scenarios)
Overload and Short-Circuit Protection
For circuit breakers:Overload(long delay)and short-circuit(short delay/instantaneous)protection are provided via thermal-magnetic or electronic trip units.
Rated Current Range:May cover 10A-200A(depending on the specific model).Motor Control
If it’s a contactor:It starts and stops three-phase motors,supporting direct-on-line(DOL)or star-delta starting.
Auxiliary contacts:It provides status feedback(e.g.,normally open/normally closed contacts).
Power Switching
If it’s a dual-power automatic transfer switch(ATS):It automatically switches between primary and backup power sources,ensuring power continuity.
Typical Application Scenarios
Industrial power distribution systems:Low-voltage distribution boards(e.g.,MCCBs and ACCBs)in factories,data centers,and commercial buildings.
Motor Control Centers(MCCs):They drive loads such as pumps,fans,and compressors.
Critical Infrastructure:Backup power switching systems in hospitals,airports,and telecom base stations.III.Technical Specifications(Based on Comparable Products in the Industry)
