Technical Specifications Rated main‑circuit current rating, 24 V control coil, multi‑pole main contact groups, auxiliary contact sets. Operating ambient temperature ‑25 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. DIN‑rail quick‑mount structure.
Functional Features 24 V electromagnetic coil drives mechanical linkage to realize main‑circuit load switching. Auxiliary contacts provide real‑time working‑status feedback and interlock signal for external control logic. Contact material resists electric‑arc ablation during frequent switching cycles.
Application Scenarios Load switching component for motor control cabinets and industrial auxiliary control loops adopting 24 V control power, applied in chemical industry, manufacturing and power‑plant auxiliary equipment.
Performance Parameters Defined continuous main‑circuit current capacity, long mechanical and electrical service life, stable 24 V coil pull‑in and release performance.
Material Composition Flame‑retardant plastic enclosure. 24 V electromagnetic coil assembly, magnetic iron‑core components. Silver‑alloy main and auxiliary contact assemblies. Mechanical spring‑linkage transmission parts. Screw‑type wiring terminals, DIN‑rail clamping hardware.
Structural Characteristics Standard DIN‑rail contactor form factor. Main‑circuit power terminals are arranged on top and bottom. Auxiliary signal terminals locate on front section. Internal 24 V coil and magnetic drive assembly actuate contact linkage mechanism.
Working Principle When 24 V control voltage energizes coil, magnetic force attracts iron‑core and drives linkage mechanism, main contacts close to switch‑on load circuit. Once 24 V coil power is removed, reset spring pushes linkage back and opens main contacts. Auxiliary contacts change synchronous status to output interlock and status feedback signals.
Installation Requirements Tighten main‑circuit wiring terminals and auxiliary wiring terminals according to torque specification. Apply 24 V control power, verify contact pull‑in / drop‑out movement and auxiliary contact signal change.
Usage Notes Only apply 24 V rated voltage for coil control loop. Comply with specified wiring torque requirement. Avoid installation location with conductive dust and corrosive atmosphere.
