Competitive price Punctual delivery Thoughtful service CE certification Specifications HDM1 moulded case circuit breaker: 1. Low voltage type. 2. Standard:IEC60947. 4. Small size,hight breaking capability. low- voltage type seriesHDM1 moulded case circuit breaker (hereinafter referred to as “Breakers” ) are one of novel breakers designed and developed with internationally advanced technique. These breakers feature small size, high breaking capability, short flashover (zero flashover for partial specifications) and anti-vibration.Breakers are provided with devices to protect circuits and power units from damage caused by overload, short circuit or under voltage. They are ideal products applied in land and vessels. These breakers can either be vertically or horizontally installed. These breakers are in conformity with the standards as follows: IEC60947-1 and GB/T14048.1-2006 General Provisions IEC60947-2 and GB/T14048.2-2008 Low-voltage breaker IEC60947-4 and GB/T14048.4-1993 Contactor and motor starter IEC60947-5.1 and GB/T14048.5-2001 Electromechanical control circuit devices Usual service condition: Altitude 2000m or below; Ambient temperature on higher than +40centigrade+(45centigradefor marine products) and no lower than -5centigrade; With resistance against moist air; With resistance against salt fog and oil fog; With resistance against mould; Max gradient:±22.5° Reliably work when suffering normal vibration of the vessel; Safely work during earthquake (4g); In medium free of explosion hazard, no air sufficient to corrode metal and damage insulation, no conductive dust; In a position free of invasion from rain and snow. Application and maintenance: Various characteristics and accessories of the breaker have been fixed by the manufacturer and shall not be arbitrarily adjusted in use. The breaker handle may be placed at three positions, respectively marking with three states of closed, open and release. When the handle is placed in release position, it shall be pulled backward to enable the breaker to buckle then close. The manufacturer will be responsible for free replacement and repair in case of damage or failure due to defect within 18 months since the delivery date under the condition that the user maintenances and uses the product as required and the seal of breaker is sound.
