Automatic machine ap 50b-3mt 50a
Automatic circuit breakers of the AP50B series are designed to conduct current in normal mode and turn off current in case of overloads and short circuits, as well as for operational switching on and off of electrical circuits. They are used to protect consumers as part of distribution equipment: in residential, public buildings and in low-voltage switchgear for industrial use, with AC circuits from 1.6 A to 63 A at voltages up to 400 V with a frequency of 50 and 60 Hz, as well as in DC circuits from 1.6 A to 63 A with voltage up to 220 V. Automatic switches AP-50 are made: two-pole for the nominal voltage of alternating current up to 500 V at a frequency of 50 and 60 Hz and direct current up to 220 V and three-pole - for the rated voltage of alternating current up to 500 V; for rated currents of phase overcurrent releases: 1.6; 2.5; 4; 6.4; ten; sixteen; 25; 40; 50 A; 63A. by the presence of phase overcurrent releases: with thermal and electromagnetic releases, only with thermal releases, only with electromagnetic releases, without releases - non-automatic switches for a rated current of 50 A; with cut-off currents of electromagnetic releases - 3.5 In, 8 In, 11 In. by the presence of an overcurrent release in the neutral wire: without a release - to the neutral wire, with a release in the neutral wire. Automatic machines with an overcurrent release in the neutral wire are made starting from the rated current of the phase releases of 16 A. The continuous mode current of the release in the neutral wire should not exceed 60% of the rated phase current; by the presence of undervoltage releases 110; 127; 220; 380; 400 and 415 V AC at a frequency of 50 Hz with the ability to turn on the release coil for power supply from an external source; without undervoltage release, with undervoltage release; by the presence and type of auxiliary contacts: without auxiliary contacts, with one changeover, with two changeover; open version in a plastic case and dust-proof version in an additional metal casing. The structure of the symbol AP50 - 3MTHXXX: AP50 - circuit breaker series; 3 - number of overcurrent releases: 3; MT - overcurrent releases: MT - electromagnetic and thermal; X - additional releases: Н - undervoltage release; D - independent voltage release; О - maximum current release in the neutral wire; XX - climatic version and category of placement: switches in a plastic sheath - UZ, TZ, XL5; switches in a metal shell with a degree of protection IP54 according to GOST-U2, T2, HL5; X - rated current of overcurrent releases: 1 - 1.6; 2.5; 4.0A; 2 - 6.3; 10.0; 16.0A; 3 - 25.0; 40.0; 50.0; 63.0A. Automatic circuit breaker AP-50 consists of the following main units: control mechanism. contact system, arcing device, overcurrent releases.
