Description

TO-100BA/3300/3302/3304/3310/3311/3312//3320/3322/3324 Marine Air Circuit Breaker

Product description:

3300: without any accessories, no extra wires on the back of the switch.

3310: with shunt release, there are 2 extra wires on the back.

Shunt release: remote opening/emergency stop power-on release

3302: with auxiliary contact, there are three red, yellow and blue wires on the back.

Auxiliary contact: opening and closing status display/signal feedback

3320: with undervoltage release, there are 2 wires on the back.

Undervoltage release: trips when the voltage is lower than a certain value (usually 380V, or 220V)

Note: With undervoltage release, the switch must be powered on before closing

3322: with undervoltage release + auxiliary contact, 5 wires behind

Undervoltage release: trips when the voltage is lower than a certain value

Auxiliary contact: open and close status display/signal feedback

3312: with shunt release + auxiliary contact, 5 wires behind

Shunt release: trips when the voltage is lower than a certain value

Auxiliary contact: open and close status display/signal feedback

3304: with double auxiliary contacts, 6 wires behind (two each of red, yellow and blue)

Scope of application:

Applicable to ships and land, AC 50Hz or 60Hz, rated insulation voltage 660V, DC to 250V and below circuits for infrequent connection and disconnection. The circuit breaker has overload and short-circuit protection devices to protect cables and lines from damage due to overheating. TO is the standard type, TG is the high breaking capacity type.

Categories:

1. According to the wiring method, it is divided into front wiring, rear base line, and plug-in wiring;

2. According to the overcurrent release type, it is divided into thermal-electromagnetic type:

3. According to the auxiliary devices, it is divided into with auxiliary devices and without auxiliary devices;

4. The auxiliary devices are divided into internal auxiliary devices and external auxiliary devices. The internal auxiliary devices include auxiliary switches, alarm switches, and shunt releases; the external auxiliary devices include electric operating mechanisms, mechanical interlocks, handle locks, and plug-in extraction devices.

Working environment conditions

1. Altitude 2000 meters and below;

2. The temperature of the surrounding medium is not higher than +45℃℃ and not lower than -25℃℃:

3. Able to withstand the influence of humid air at sea:

4. Able to withstand the influence of salt spray;

5. Able to withstand the influence of oil mist;

6. Able to withstand the influence of mold:

7. The maximum inclination is 22.5℃℃

8. The circuit breaker can work reliably when subjected to normal vibration of the ship;

9. In a medium without explosion hazard, and there is no gas and conductive dust in the medium that is enough to corrode metal and destroy insulation;
