Bistable-pulse relay RPB-1ZI-A230, 1 changeover contact, 230 V AC, 16 A /250 V AC, withstand 120 A 864388

Bistable/Impulse Relay – Reliable Lighting Control

This bistable (on-off) impulse relay is an ideal solution for controlling lighting in public and residential buildings. Its non-memory design allows for simple and effective circuit management. Compact dimensions (17.5 mm width) allow for mounting in standard installation boxes, making integration with existing infrastructure easier.

The RPB-1ZI-A230 relay is characterized by high resistance to surge currents – up to 120 A for 20 ms – making it particularly useful in applications with inductive loads, such as LED fluorescent lamps or electronic transformers. The use of AgSnO2 contacts ensures reliable conductivity and long device life. Rated voltage of 230 V AC (50/60 Hz) guarantees compatibility with most standard electrical installations.

Design features and application

The relay is designed to work with impulse buttons and stairwell switches, allowing convenient lighting control from different points. A single-pole changeover contact (1Z) allows for simple connection to the circuit. The module housing allows for easy mounting on a DIN rail or directly in a flush-mounted box. This makes the relay suitable not only for new installations, but also during the modernization of existing lighting control systems.

Advantages and benefits
