Motor-protective circuit-breaker
Overview |
| |
| Definition |
| Motor-protective circuit-breakers are circuit-breakers
used for switching, protection and isolation of circuits primarily
associated with motor loads. At the same time, they protect these motors
against destruction from locked-motor starting, overload, short-circuit
and phase-failure in three-phase power supplies. They have a thermal
release for protection of the motor winding (overload protection) and an
electromagnetic release (short-circuit protection). |
| |
The following accessories can be fitted to
motor-protective circuit-breakers:
Undervoltage release,
Shunt release,
Auxiliary contact,
Trip-indicating auxiliary contact.
