Modular Contactor VCX GACIA 2-pole 25A 4NO 230V

VCX GACIA Modular Contactor 2-pole 25A 4NO 230V is a compact DIN-rail mount switching device designed to control electrical circuits and loads within its rated capacity. The unit integrates a 230 V coil and a set of four normally open auxiliary contacts alongside two main switching poles, offering centralized switching for lighting, heaters or small motors in residential and light commercial installations.

Advantages

The contactor combines a small modular form factor with straightforward DIN-rail installation for distribution boards, allowing space-efficient integration into electrical panels. Its 25 A rated current and two main poles provide reliable switching for mid-range loads, while the four normally open auxiliary contacts expand control and signaling possibilities without additional modules. The 230 V coil ensures compatibility with common control voltages used in building automation and electrical systems.

Suitable for

• Lighting circuits in residential and small commercial buildings
• Switching of electric heaters and warm-floor systems within rated limits
• Control of small single-phase motors and pumps compatible with the device rating
• Integration into automation systems for remote or scheduled switching tasks

Key specifications

• Number of main poles: 2 (two-pole switching)
• Rated current: 25 A
• Auxiliary contacts: 4 normally open (4NO)
• Coil/control voltage: 230 V AC
• Mounting: DIN-rail mounting for distribution boards
• Application area: residential and light commercial switching and automation

How to use

Install the modular contactor on a standard DIN-rail inside the distribution board, ensuring power is isolated before making connections. Connect incoming and outgoing conductors to the two main poles for the load to be switched and wire the four auxiliary contacts to the control or signaling circuits as required. Apply 230 V to the coil terminals to actuate the contactor; ensure wiring follows local electrical codes and that conductor sizes match the rated current. Verify correct operation by energizing the coil and observing the switching of the main poles and auxiliary contacts under no-load and then load conditions.

Usage recommendations

Use the contactor within its 25 A rating and for intended AC loads; avoid continuous operation near the maximum rating without adequate thermal considerations. Select appropriate circuit protection (breakers or fuses) upstream of the contactor, and perform regular inspections of terminal tightness and contact condition in line with standard maintenance schedules for building electrical equipment.
