Impulse relay with central control function Z-SC230/1S1W 265324

Professional impulse relay for central control of electrical installations

The EATON Z-SC230/1S1W impulse relay is a compact industrial-grade solution designed for reliable central control of electrical circuits from multiple points. The device, with a width of 2 modules (35mm) and a depth of 60mm, is mounted on a DIN rail, features a mass of 0.263 kg, and has dimensions of 80×70×17.5mm.

Electrical parameters and load capabilities

Model Z-SC230/1S1W operates at a supply voltage of AC 250V and a control voltage of AC 230V (50Hz), ensuring full compatibility with standard European installations. The device achieves a rated making current of 16A and a maximum current at cos φ = 0.6 equal to 24A, guaranteeing safe operation even under larger loads.

The contact configuration includes 1 NO (normally open) contact and 1 changeover contact, allowing for flexible management of single circuits. The switching capacities are impressive - for incandescent bulbs up to 1980W, standard fluorescent lamps 1020VA, fluorescent lamps with parallel compensation 1150VA, and with DUO compensation up to 1820VA. This allows the relay to handle various types of lighting - from traditional bulbs to modern LED lamps.

Construction and operational safety

The relay is made of flame-retardant, chlorine-free, and halogen-free materials, which eliminates the release of toxic gases during combustion and meets RoHS environmental standards. The design features dampened operating noise, which is particularly important in residential and office buildings where silence matters.

The device features a dedicated manual start/test button located on the front of the unit, enabling quick diagnostics and status control. Additionally, it is equipped with special terminal entries for the control coil and for the main contacts, simplifying the installation and maintenance process.

Practical application and operating conditions

The impulse relay is used for controlling lighting in corridors, stairwells in multi-family buildings, and office rooms where switching on/off from multiple locations is required while maintaining a load of up to 16A. It finds application in smart building management systems, home automation, and industrial installations requiring central control.

The device operates reliably in temperatures from -20°C to +45°C, allowing for indoor installation. It complies with RoHS standards and bears the CE marking, confirming full compliance with European safety standards.
