Series 020 - Modular Step Relays 16 A. (Accessories) - FINDER

Modular step relays are electromechanical switching devices designed for alternating control of lighting or electrical loads from multiple points. The Series 020 from FINDER offers a compact 1-pole design rated at 16 A, suitable for DIN rail mounting in standard distribution boards. These relays feature a bistable mechanism that toggles the output state with each voltage pulse, eliminating the need for a continuous control signal. Key technical parameters include a rated impulse voltage of 4 kV, coil voltages available in AC/DC from 12 to 230 V, and a mechanical endurance of over 10 million operations. The modular width of 17.5 mm (1 module) allows for high-density installation, while the integrated manual override and status indicator simplify commissioning and maintenance.

These step relays are primarily deployed in stairwell lighting, corridor control, hotel room automation, and large-area lighting management systems. They are ideal for applications requiring centralized or decentralized switching from push-button panels, timers, or building management systems (BMS). The robust design ensures reliable operation in industrial control cabinets, commercial electrical installations, and residential smart grids. With a rated insulation voltage of 250 V AC and a pollution degree of 2, they are suitable for environments with moderate electrical noise.

The main subcategories include the standard 020.0 step relay (16 A, 1 NO contact) and the 020.2 version with a manual pushbutton. The article code typically follows the pattern 020.0.xxx.xx, where xxx denotes the coil voltage (e.g., 024 for 24 V AC/DC, 230 for 230 V AC). Accessories like the 020.0.0.024.0000 (24 V coil) and 020.0.0.230.0000 (230 V coil) are common stock items. These relays are often paired with push-button switches or occupancy sensors for complete control solutions.
