Product Overview：
HTM6, HTM6LY, HTM6RT, HTM6E and HTM6EL series of circuit breakers are new upgraded circuit breakers researched and developed by the company combined with the advantages of similar international products and demand of domestic and international markets.
With insulation voltage up to 1000V, the circuit breaker is applicable for distribution systems of AC50Hz, rated working voltage 690V and rated working current from 10A to 800A, used to distribute electric power energy, protect circuits and power equipment against overload, short circuit, undervoltage and so on, also can be used for infrequent startup of motor and protect it from overload, short circuit or undervoltage.
Product Feature:
It is featured with small size, high breaking, short flashover, etc., is the ideal product for users. It can be vertically installed or horizontally installed.
STM6DC series DC moulded-case circuit breaker (hereinafter referred to as circuit breaker) is suitable for DC systems of rated voltage up to and including DC 1000V and rated current 10~800A, used to distribute electric power energy, protect circuits and power equipment against overload, short circuit and so on.
The products can be fed with wires from top and bottom, and it is polarity-free.
It complies with the standards IEC60947-2, GB14048.2, etc.

Feature 1: Current limiting capacity
Current-limiting refers to limit of the increase of short-circuit current in the loop, and in the loop protected by EKM8, peak
value of the short-circuit current and the I2t energy in the circuit will be much smaller than the prospective value.
U-shaped static contact
Unique U-shaped static contact can achieve pre-breaking technology:
The so-called pre-breaking technology refers to when short-circuit current flows through the contact system, electric power generated by U-shaped static contact and moving contact is mutual exclusive. The greater the short-circuit current is, the greater the repulsion of the electromotive force, and it is generated together with the short-circuit current at the same time. Before the trip action occurs, the electrodynamic repulsion force can make the static and moving contact separation, by increasing the arc to increase the equivalent resistance between themto achieve the purpose of suppressing increase of short-circuitcurrent.Feature 2: Modularize accessories
Accessory: For the circuit breakers of the same frame, they has uniform sizes regardless of the breaking capacity and rated current
Modularized accessories have insulation function, which is easy for hot-line operation and installation
