Product characteristics
SRM3E series plastic shell circuit breakers, with rated insulation voltage of 1140V, are suitable for infrequent switching and infrequent starting of motors in circuits with AC 50Hz (or 60Hz), rated working voltage of 690V and rated working current up to 1600A.
The circuit breaker has overload long delay anti-time limit, short-circuit short delay anti-time limit, short-circuit short delay fixed-time limit, shortcircuit instantaneous and under-voltage protection function, as well as residual current protection function (optional), phase loss protection function (optional), which can protect the line and power supply equipment from damage.
According to its rated limit shortcircuit breaking capacity, the circuit breaker is divided into S-type (standard type), H-type (high score type), R-type (current limiting type) three types.
