Product Description

The table below shows the maximum number of light fittings for each relay, according to the type, power and configuration of a given lamp. As an indication, the total acceptable power is also mentioned. These values are given for a 230 V circuit with 2 active conductors (single-phase phase/neutral or two-phase phase/phase). For 110 V circuits, divide the values in the table by 2.To obtain the equivalent values for the entire 230 V three-phase circuit, multiply the number of lams and the maximum power output: by (1.73) for circuits with 230 V between phases without neutral; by for circuits with 230 V between phase and neutral or 400 V between phases.

Applicable scope
EIR series impulse relay coils are triggered by impulses and the contacts are closed. The product has two stable mechanical positions, and the contacts will open temporarily with the next impulse. Each received impulse will reverse the position of the contact and can be controlled by an unlimited number of buttons. And has the characteristics of zero power consumption.
Impulse relay can be used to control the lighting circuit through the button. The circuit consists of incandescent lamps, halogen lamps, etc. (resistive load); fluorescent lamps, discharge lamps, etc. (inductive load).
Conform to standard:IEC/EN 60669-2-1,IEC/EN 60669-2-2

 

The AC Residual Current Circuit breaker is a safety appliance that protects personal safety and prevents electrical fires, can prevent electrical equipment from being damaged. It can be widely used in power distribution systems.

 

Product Benefits :

• Air circulation
  When two poles are placed adjacent to each other, these channels form a tunnel resulting in effective air circulation around individual poles
• Bi-connect Termination Possible
  Choice to use Busbar and/or cable in the same terminal,provides reliable termination
• Din Rail Mounting
  Two step snapping mechanism for easy & efficient mountion in 35mm DIN Rail steadily
