Model Selection example:
Ex9M1N TM 160 3P refers to an
Ex9M1 series 3 pole AC moulded case circuit breaker with frame size of 160A,
breaking capacity of 50kA, rated current of 160A, providing thermo-magnetic type power distribution protection.
Note:
1)
The capacity of thermo-magnetic type can be increased to 500A; the capacity of electromagnetic type can
be increased to 630A; the same for DC and residual current protection circuit breakers;
2)
1P/2P is only available for products with 160A and 250A frame size, no electromagnetic motor protection; 1P
product is only available with two types of breaking capacity: S/N.
Note 1):
1P/2P is only available for products with 160A and 250A frame size; 1P product is only available with three types of
breaking capacity: B/S/N.
Note:
1)
Only applicable to Ex9M2/3/4/5 electronic type circuit breaker, no motor-driven version for Ex9M6 product;
2)
Only applicable to Ex9M6 motor-
driven version electronic circuit breaker.
