JHM1 series plastic shell circuit breaker
Scope of Application
The JHM1 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is a new type of circuit breaker developed by our company using international advanced design and manufacturing technology. According to its rated ultimate short-circuit breaking capacity (Icu), it is divided into C-type (low breaking type), L-type (standard type), M-type (high breaking type). This circuit breaker can be installed vertically (both vertically) or horizontally (both horizontally). 2. This circuit breaker product complies with the following standards: 3. IEC60947-1 and GB/14048.1 General Provisions 4. IEC60947-2 and GB/14048.2 Low Voltage Circuit Breakers 5. IEC60497-4 and GB/14048.4 Contactors and Motor Starters 6. IEC60947-5.1 and GB/14048.5 Electromechanical Control Circuit Electrical Models and Their Meanings One of the circuit breakers. Its rated insulation voltage is 800V, (JHM1-63 is 500V), suitable for AC 50Hz, rated working voltage type, H-type (high breaking type) four categories. This circuit breaker has the characteristics of small size, short breaking high flying arc (some specifications have zero flying arc), and anti vibration. It is an ideal product for ships and land with 690V and below (JHM1-63 is 400V) and rated working current up to 800A circuits for infrequent switching and motor starting. Use it. Circuit breakers are equipped with overload, short circuit, and undervoltage protection devices, which can protect the circuit and power equipment from damage.
JH note: 1. Circuit breakers for power distribution have no code; The circuit breaker for protecting the motor is represented by 2. 2. Direct operation without code; Electric operation is represented by P; The operation of rotating the handle is represented by Z. Applicable working environment M1-
