GSM1 Series Moulded Case Circuit Breakers GSM1 series moulded case circuit breakers suitable for turn-on or turn-off not frequently and starting a motor not frequently in the circuit of AC50Hz, rated nsulation voltage up to 800V(GSM1 -63 is 500V), rated working voltage 690V or below(GSM1 -63 is 400V), rated working current up to 800A.The breakers of 4 poles are mainly suitable for cable short cuicuit protection,cable overload protection and turn-on or turn-off not frequently in the power supply system, mean while can open neutral conductor and leg conductor together as to keep from high electric potential transferring and protect operators.Besides having short cuicuit and overload protection for cuicuit and motor.the breakers can assembly many function modules such as under-voltage realease,shunt release,alarm contact , anxiliary contact,motor-driven operation device and so on,meeting all kinds of protection and control functions. ftStrii ( CONFORM TO STANDARDS ) The breakers comply with the demands of the following standards: Low-voltage switchgear and control gear: Low voltage breakers Low-voltage switchgear and control gear: Part 11 Low voltage breakers Code of N-pole(no code for 3 poles product): A or B Code for application: no code for power distribution 2 for motor protection Code for release pattern and inner accessories (see Table 1) The first digit stands for release pattern.The other twodigits stand for code of inner accessories 2 il^^l^rfjM () JK^0§§ Only has electromagnetic (instantaneous)type release 3:^z2j-E&fiM (Sit) JK^0§§ Thermo-electromagnetic (double) type release 3N 4 Codefor the pole number: 3^ 4 Wii^TjJ^'- Code for the operation means: ^;lflJilIclJill'/P7cft^ No code for handle operation dirrectly "P" ^z^JfUfp Power driven "Z" f^z^JE^filJ|{/pTuming handle Code for the breaking ability (No code for 4 poles product L-^)f=?£y typical type M-^M^MjW. second high breaking type H-r^]^}ifT§y hige breaking type ttW^%^Mf^^M Code for the frame grade l^vfj^^ Code for designation ■ 111145^^ ^I^SSi^ Moulded case circuit breakers fi^lM"^" Code for company

For GSM1-400,630,800, codes 248,348,278,378 only have one pair of auxiliary contacts(a normal opened, a normal closed),but 268,368 have three pairs of auxiliary contacts. For the specification 6A of GSM1 - 63,only has short circuit.
