.Product Overview
The ABB 200-APB12/200APB12 is a compact molded case circuit breaker(MCCB)from ABB,designed for low-voltage power distribution systems(AC 400V/690V).It provides three protection stages:long-time overload protection,short-time short-circuit protection,and instantaneous short-circuit protection.Its core advantages include:
High breaking capacity:Supports short-circuit breaking from 36kA to 150kA(depending on the model),adapting to high short-circuit current scenarios.
Modular design:Expandable accessories(such as auxiliary contacts,alarm contacts,shunt releases,and undervoltage releases)meet intelligent monitoring needs.
Environmental adaptability:With protection levels of IP20(standard)or IP40/IP65(protected),it is suitable for indoor and humid environments.Compatibility:Compliant with IEC 60947-2 and GB 14048.2 standards,compatible with other ABB low-voltage electrical devices(such as contactors and soft starters).
Core Parameters and Features
Rated Parameters
Rated Current(In):
Typical range:16A to 200A(depending on the model);select the appropriate specification based on the load current.
Rated Voltage(Ue):
AC 400V/690V(50/60Hz),suitable for low-voltage power distribution systems.
Number of Poles:
3-pole(3P):Suitable for three-phase,three-wire systems(such as motor control).
4-pole(3P+N):Suitable for three-phase,four-wire systems(such as commercial building power distribution).
Breaking Capacity
Ultimate Short-Circuit Breaking Capacity(Icu):
Typical values:36kA to 150kA(depending on the model and voltage level).This indicates the maximum current the circuit breaker can safely interrupt in the event of a short circuit.Operating Short-Circuit Breaking Capacity(Ics):
Typically 50%to 100%of Icu,indicating the circuit breaker’s ability to continue operating after a short circuit.
Trip Unit Type
Thermo-Magnetic Trip Unit(TM):
Overload Protection:A bimetallic strip senses current,achieving an inverse time characteristic(e.g.,Class B curve:3-5 Inch trip time 10s-30s).
Short-Circuit Protection:An electromagnetic coil senses high instantaneous current,providing rapid tripping(e.g.,5-10 Inch instantaneous action).
Electronic Trip Unit(ET/PR220DS):
Supports adjustable protection parameters(e.g.,long overload delay,short short circuit delay,and short circuit instantaneous action),making it suitable for protecting precision loads.
Extensible communication capabilities(e.g.,Modbus RTU)enable remote monitoring and fault diagnosis.
