Flexible Pole and Contact Setup: Available in 1-pole, 2-pole, 3-pole, and 4-pole configurations to match different phase requirements. Supports flexible auxiliary contact blocks (like 2NO + 2NC, ZTCF3 auxiliary contacts) and air time delay units (ZTCST, ZTCSR, ZTCSS).
Extreme Durability: Heavy-duty mechanical and electrical endurance, optimized for frequent operations in harsh environmental conditions (ideal for construction, metallurgy, and hosting equipment).

Applications

The high ampere contactor series is designed for a variety of industrial scenarios, including:

Motor Control: Starting and stopping heavy motors in industrial machinery, elevators, escalators, hoisting, and metallurgy setups.
Power Distribution: Safe switching and control of distribution circuits in commercial buildings, workshops, rural area power networks, and green energy systems (e.g. wind power distribution).
Resistive and Inductive Loads: Direct control of large heating elements, electric stoves, and high-power commercial lighting systems.
Capacitive Loads & Transformers: Making and breaking of capacitor banks in reactive power compensation systems to improve the power factor.
