- ERM1 series moulded case circuit breaker ( hereinafter referred
to as the circuit breaker ),is suitable for occasional conversion
and motor start ( Inm<=630A type and below )under the circuit of
AC 50Hz/60Hz,rated insulation voltage of 690V(500V for
ERM1-63),rated operational voltage of 400V and below and rated
current to 1250A.The circuit breaker has protection function to
avoid overload ,short circuit and under-voltage,for assuring the
prevention from damage of circuits and power-supply devices . - The
circuit breaker can be classified into three types of L
(standard),M (moderate high breaking )and H (high breaking
)according to the rated limit short circuit breaking capacity (
Icu).It has features of small volume ,high breaking and short
flashover ,vibration resistance ,etc . - It can can be installed
vertically (vertical assembly )or horizontally (horizontal assembly
).It has isolation function. - The circuit breaker conforms to
requirements of IEC 60947-2 and GB14048.2 standards.
