• Air temperature: use temperature -30℃~+60℃, storage temperature -40℃~+70℃.
• Altitude: The altitude of the installation site does not exceed 2000 meters, and the altitude of more than 2000 meters should be derated for use.
• Atmospheric conditions: The relative humidity of the air at the installation site does not exceed 50% at +40°C, and the average humidity of the wettest month does not exceed 90% at +20°C.
• Installation category: The installation category is Ⅲ and Ⅲ. Pollution degree: Level 2. Installation method: Use TH35-7.5 standard rail installation.
• Installation conditions: The inclination between the installation surface and the vertical surface should not exceed 5°, and the installation site should be free of significant impact and vibration.
• Wiring method: Use screw compression connection to ensure fast and safe connection of conductors.

Type b Circuit Breaker Applications:

A type B MCB trips when the current is 3 to 5 times the rated current with an operating time of 0.04 to 13 Seconds. It is used for purely resistive loads that are non-inductive loads or with a very small inductive load which has no considerable amount of inductance.

These types are mainly used for low power domestic applications like lighting circuits, home wirings, etc.

The Over-Current Protection Property

MCB Selection

The first characteristic is the overload which is intended to prevent the accidental overloading of the cable in a no fault situation. The speed of the MCB tripping will vary with the degree of the overload. This is usually achieved by the use of a thermal device in the MCB.

The second characteristic is the magnetic fault protection, which is intended to operate when the fault reaches a predetermined level and to trip the MCB within one tenth of a second. The level of this magnetic trip gives the MCB its type characteristic as follows:

· The third characteristic is the short circuit protection, which is intended to protect against heavy faults maybe in thousands of amps caused by short circuit faults.

· The capability of the MCB to operate under these conditions gives its short circuit rating in Kilo amps (KA). In general for consumer units a 6KA fault level is adequate whereas for industrial boards 10KA fault capabilities or above may be required.
