| Structural characteristics | |
| 1. Fully in line with the main electrical performance lEC ~
,60439-1: 1992 and GB 7251.1-1997 requirements. 2 auxiliary circuit
with local, remote, automatic control and in-situ, remote control
switching function, DC contactors can be used to maintain. 3, the
main switch by the electronic and thermal magnetic tripping with
instantaneous trip protection option, the main switch with the next
level with the abolition of instant protection from the grade trip,
and self-investment, manual operation and automatic switching
function. 4 feed the main switch is instantaneous tripping circuit
and thermal magnetic trip protection, when the user requirements,
leakage protection can be installed.5 motor control circuit has a
transient short-circuit, overload, undervoltage release and phase
protection. 6. By the electric circuit with ammeter, voltmeter. |
