ABB A300-30-11 AC Contactor 300A 3-Pole 400V 1NO+1NC Auxiliary Legacy Replacement

Product Overview:  ABB A300-30-11

Parameter Specification
Manufacturer ABB 
Model A300-30-11
Product Name Large-frame AC motor contactor
Series / Family ABB A-Series (successor family: AF-Series)
Product Type 3-pole AC contactor with auxiliary contacts — not a circuit breaker, not a relay, not a soft starter

Application & Fault Scenarios

  • Suitable for 400 V three-phase motor circuits up to 300 A AC-3, including mills, crushers, large compressors, fans, pumps and hoists. Typical faults: coil fails to pull in due to wrong control voltage, contactor chatters from worn core or low voltage, main contacts overheat under sustained overload, auxiliary contacts fail to signal, mechanical jamming after long idle periods, and phase imbalance causing motor overheating. Check coil voltage, control wiring, contact wear, torque settings and overload protection before replacement.

FAQ

Q1: What is the ABB A300-30-11?
A legacy ABB A-Series 3-pole AC contactor, rated 300 A AC-3 at 400 V, with 1 NO + 1 NC auxiliary contacts for heavy motor control applications.
Q2: Can AF300-30-11 replace A300-30-11?
Often yes, but not automatically. AF300-30-11 is the newer AF-Series equivalent; coil voltage, auxiliary contacts, dimensions and mounting must be checked before substitution.
Q3: What does “-11” mean in A300-30-11?
The “11” usually indicates 1 NO + 1 NC auxiliary contacts built into the contactor. The coil voltage is defined by the suffix code after the main model number.
