The Installation Contactor Rail 16A 230V/AC/1NO is a DIN-rail impulse relay used to control lighting circuits in order to manage energy consumption efficiently. Each time voltage is applied to the coil terminals (A1–A2) — whether as a pulse or a continuous voltage — the relay toggles its contact state. This ratchet mechanism means the relay operates as a switch: press to open, press again to close (operating sequence: 0–1–0–1–0…).

Impulse relays of this type are used to connect and disconnect lighting circuits via parallel push buttons from multiple positions (two-way / three-way switching, also known as alé-retour), and as memory elements in automation circuits. The supply voltage covers 110–240V AC/DC, while the control coil operates at 230V AC.

Key Features

• 1NO (normally open) contact configuration
• DIN rail mounting for standard distribution board installation
• Ratchet (impulse) mechanism — toggles on each voltage pulse
• Control voltage: 230V AC; supply voltage: 110–240V AC/DC
• Module width: 17.5mm (1 DIN module)

Product Benefits

• Parallel push-button control from multiple locations reduces wiring complexity versus conventional multi-way switching
• Toggle-on-pulse logic means any standard momentary push button can control the circuit
• DIN rail mounting integrates cleanly into existing distribution boards without additional hardware
• 110–240V supply range covers both single-phase and industrial supply voltages
• Compact 17.5mm single-module width conserves space in crowded distribution boards
