Product Description
Moulded case circuit breaker SEM1-400L/3300
SEM1 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 SEM1- 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 be installed vertically (vertical assembly) or horizontally (horizontal assembly).
It has isolation function, with its corresponding symbol .
The circuit breaker conforms to requirements of IEC60947- -2 and GB 14048.2 standards.

Moulded case circuit breaker SEM3 series
The SEM3 series moulded case circuit breaker (hereinafter referred to as the circuit breaker),a new style with rated insulation voltage of 800V, is adopted to the international advanced design and R&D of manufacturing technology by the company, and is suitable for occasional conversion and motor protection(the rated current >630A type without motor protection )under the circuit of AC 50Hz 60Hz, rated voltage of 690V and below (400V for SEM3-63),as well as rated current to 800A. 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 two types of L(standard) and M (moderate high breaking )according to the rated limit short circuit breaking capacity (Icu).
It has features of small volume, high breaking and short fiashover(zero frashover of partial sizes), vibration resistance, etc.
It can be installed vertically(vertical assembly ) or horizontal (horizontal assembly).
The circuit breaker conforms to requirements of GB14048.2 standard.
