For measuring mean maximum current value, when it is 8 min or 15 min or 30 min. Model: DE-M96   ME-M72                       Accuracy: Class3.0Specification: 8min 5A,  15min 5A,  30 min 5A,                         8min 1A,   15min 1A(No specification for 30 min 5A for SF-M48)With bimetal movement and thermal delayed indicator for measuring the maximum mean load during aperiod of 8 or 15 minutes, eats red maximum pointer. Lead seal can protect resetting knob of maximum pointer. Scale compressed at the beginning, convenient reading from 25% of full-scale deflection. Accuracy of maximum load indication 3%. Referred to the maximum pointer. Response time 8 or 15,30 minutes(to be specified when ordering).Heat resistance: Case of non- combust

Model:DE-T96, DE-T72, DE-T48, DE-C96, DE-C72, DE-C48Accuracy: Class1.5Specification:30V, 50V, 75V, 100V, 120V, 150V, 250V, 300V, 450V, 600V(For 450-380KV,should be used with potential transformer whose secondary voltage 100V).

It applies to the end of power supply system of rated voltage 230V (or 400V), ratedcurrent at most 240A and rated current of each short-circuit protector at most100A. It is a complete set of equipment to protect from overload, over-voltageand leakage. Note: rated current depends on that of incoming circuit with one or multi wires bymanufacturer. If there is one wire or above incoming circuit, rated current ofcombined electric appliance is the sum of all incoming circuits (three-phase shouldbe converted into the sum of single phase current).It conforms to the standard of GB7251.3-1997.

Surge Protective Device is pre-installed distributing equipment. It can be used inmining, industrial company, gas field, new developing district, building ground,especially applies to city public distributing facility, high building distributor,residential district and resort. Its characteristics are as follows: smallsize, convenience to operate in site, easy operation, high security, good outlineand cooperative ability.Surge protective device country used before are made from ordinary steel board, aluminaalloy board and stainless steel and exists such problems: weak ability toanti-insulation, anti- radiation and anti-erosion, easy to tarnishing and condensation,so in recently years, non-metal (glass and fiber cement) material cabinettype substations are developed.Packing: cartons

Simply named switchgear cabinet, is transporting and distributing control systemof single generatrix for receiving and distribute power with 3.6-12kV, 3-phase AC50Hz.It's mainly used in receiving power, sending power and large high voltage motor'sstarting of power plant, medium & small size power plant, industrial companyand power system. Its functions are controlling, protecting and monitoring.
