DW15-200, 400, the 630 circuit breaker (hereinafter referred to as the circuit breaker) and DWX15 universal type current limiting circuit breaker (referred to as the current limiting circuit breaker) rated current from 100A to 630A; AC rated voltage 50Hz from 380V to 1140V (current limiting circuit breaker to 660V). The main circuit breaker in distribution network is used to distribute electric energy, protection circuit and power equipment overload, undervoltage voltage and short circuit, also can be in AC 50Hz, 380V power system to protect the motor overload, undervoltage and short circuit voltage. Under normal conditions. The circuit breaker can be used as the line is not frequent conversion and motor is not frequent starting purposes. Current limiting circuit breaker because of the current limiting characteristics, especially for short circuit to appear big possible network.

1, the auxiliary contact vheating current for 6A,

2, the auxiliary contact with six pairs of contact, normal delivery: three often three normally closed. The special needs of users can provide two normally open four normally open, normally closed normally open two four.

Short circuit protection apparatus 5, auxiliary contacts of the recommended RL6-25/6 fuse 1 by usage

A, distribution;

B, the protection of motor.

2, according to the selection of the protection performance

A, select the type (with overcurrent protection in three segments characteristics);

B, a non selective type (with overcurrent protection in two segments (characteristics) limiting the circuit breaker).

3, according to the drive device is divided into

A, a handle direct drive (positive central handle direct drive and direct drive side handle, 1140V only for side);

B, an electromagnet drive (compatible with a handle transmission);

C, motor drive.

4, press release category

A, with over-current release and shunt tripping device;

B, with over current tripping device, shunt tripping device and undervoltage instantaneous tripping device;

C, with over current tripping device, shunt tripping device and under voltage delay release.

5, according to the overcurrent protection type

A, short circuit instantaneous action (electromagnetic);

B, overload long delay and short-term instantaneous action (thermo electromagnetic and electronic);

C short circuit, overload long delay, delay and super short circuit instantaneous action (Electronic) except for limiting current circuit breaker.

6, according to the under voltage protection type

A, instantaneous action;

B, delay action.

7, according to the main circuit wiring way points

A, plate and inlet line (import and line level);

B, plate forward outlet (vertical wire inlet and outlet);

C, plate, plate after the forward line outlet (the vertical line, horizontal line);

D, in front of the plate, plate after line outlet (vertical outlet, horizontal feed line).

Note: only the top two drawer. A, the highest temperature of the surrounding air is not more than +40 DEG C, the average temperature of the air around the 24h of not more than +35 DEG C, the ambient air temperature lower limit value is not lower than -5 DEG c;

B installation location, altitude not exceeding 2000m;

C, air relative humidity of not more than 50% in the surrounding air temperature of +40 DEG C; relative humidity at low temperature can be high, the wettest month average maximum relative humidity is 90%. At the same time, the average monthly minimum temperature of the month is +25 DEG C, and taking into account due to temperature changes occur on the surface of the product of the condensation;

D, the pollution level: Grade Three

E, shock and vibration: if your order is needed by the user and manufacturer, negotiation;

F, the circuit breaker should be according to the installation instructions to complete the installation or indoor installed separately and vertical deviation less than 5 degrees (on the mine slope of no more than 15 degrees);

G circuit breaker, rated working voltage 1140V for the installation of class III, rated voltage 660V and below the circuit breaker for the installation of class IV. The auxiliary circuit installation categories except under voltage release coil, the primary coil power transformer for the installation of the same category with circuit breaker, the others are for the installation of category III.
