CNHUNG MCB BKN miniature circuit breaker

BKN Miniature Circuit Breaker

Application

BKN series circuit breaker is used inlighting distribution system or motor distribution system for protectionoverload and short-circuits in the system. The product is neoteric instructure, reliable and excellent in performance. It has high breakingcapacity, can trip quickly, and its case and items are adopted by highfire-resistant and shockproof plastic. The product, with long life, is mainlyused in AC 50HZ/60HZ single-pole 230V or two, three, four poles 400V circuitfor overload and short-circuit protection as well as for infrequent on-and-offswitching electric equipment and lighting circuit in normal case. The productscomply with IEC 60898.

StoreGuidance

1. When products need store for a long time, not control the productstore environment, the metal and paint coat will be corroded. So, take care.

2. Products must store with room temperature and dry environment.Sealing when under high humidity environment.

3. Don’t store the products with acid volatile liquid and acid gastogether. Don’t store in high dust environment.

4. Don’t store the products in high temperature and humidity orlowest temperature for a long time; please install and use as soon as possible.

5. Don’t contact the link wire before products used normally,preventing corrosion from pre-contacting.

6. Please inform and operate under the manufacturer' advisereferring to special store environment such as high temperature and humidity,islands near equator, ultra-low temperature area.

TransportationGuidance 

1. Long distance transported with the matching distribution box,circuit breaker should package separately and fixed when you use.

2. Desiccant should be placed within package under the wetenvironment of long-distance transportation.

3. Products by sea should with sealed package: using the vacuumsealed packaging or plastic film packaging in a cabinet or box with products.Preventing corrode metal parts from raining, watering, high-humidity andtemperature.

4. Besides sealed package by sea, please use normal transportpackaging to protect such as wooden boxes, iron boxes, cabinets, etc.

5. Avoiding contact acid gas and liquid during transportation.

6. If products are caught in the rain or corroded duringtransportation, please use after the manufacture testing.
