TG,TO series molded case low-voltage circuit breakerDetailed product description：

1、 Scope of application
The TG and TO series plastic shell low-voltage circuit breakers are suitable for infrequent connection and disconnection in circuits for ships and land, with AC 50Hz or 60Hz, rated insulation voltage of 660V, DC to 250V and below. Circuit breakers have overload and short-circuit protection devices, which can protect cables and lines from damage due to overheating. TO is the standard type, TG is the high resolution type.
This product is manufactured using technology imported from Terasaki Electric Industries Co., Ltd. in Japan.  

2、 TG, TO series molded case low-voltage circuit breaker models and their meanings:

T□	-	□	B□
'TO' represents standard type; TG "stands for high breaking type		Rated current of shell level (A)	Design number, TO series is "BA", TG series is "B"

3、 Category
1. According to the wiring method, it can be divided into front board wiring, back board baseline, and plug-in wiring;
2. Divided into thermal electromagnetic type according to overcurrent release type;
3. Divided by accessory devices into those with accessory devices and those without accessory devices;
4. Accessory devices are divided into internal accessory devices and external accessory devices. There are four types of internal accessory devices: auxiliary switch, alarm switch, and shunt release; There are five types of external accessory devices: electric operating mechanism, mechanical interlocking, handle locking, and plug-in extraction device.
