Cutler-Hammer KW3400F Product Details
The Cutler-Hammer KW3400F is a molded case circuit breaker(MCCB)for industrial power distribution systems.Cutler-Hammer is an Eaton brand.This series of circuit breakers is primarily used to protect electrical equipment and lines from overloads and short circuits.
The following are the main features and technical specifications of this circuit breaker:
Product Type:Molded Case Circuit Breaker(MCCB)
Model Series:KW Series
Core Functions:
Overload Protection:When the current exceeds the set value,the thermal-magnetic release within the circuit breaker activates,automatically disconnecting the circuit after a specified delay.
Short-Circuit Protection:When a short-circuit fault occurs,the electromagnetic release immediately operates,rapidly disconnecting the circuit to prevent equipment damage or fire.
High Breaking Capacity:With high short-circuit breaking capacity,it can safely and reliably interrupt current even in high-current faults.
Technical Specifications:
Frame Current:400 A.This value represents the maximum rated current the circuit breaker can handle.
Trip Unit:Typically uses a thermal-magnetic or electronic trip unit,adjustable depending on the specific application.
Number of Poles:Typically three or four poles.
Applications:
Industrial Power Distribution:Used as a main switch,branch circuit protector,or motor protection in low-voltage power distribution systems in factories,commercial buildings,and data centers.
Equipment Protection:Used to protect critical equipment such as transformers,capacitors,and generators.
