SRSB-1(4102-1) Relay

The SRSB-1 (4102-1) Relay, specifically designed for diverse circuit scenarios, boasts a core differentiating advantage in its "multi-contact arrangement + medium-to-high safety insulation": It innovatively supports three contact arrangements (A/B/C), unlike the single A-type arrangement of the SRSB (4102) series. This allows for adaptation to different circuit control needs without changing the product model, completely resolving the pain points of buyers having to stock multiple specifications and limiting circuit design. Its 2500VAC high dielectric strength combined with 1000MΩ (500VDC) ultra-high insulation resistance, along with a UL F-level insulation system, precisely meets the circuit isolation requirements for medium-to-high safety levels. Its lightweight 6g body and standard PCB layout adapt to high-density installation scenarios. With a wide nominal voltage range of 3-24VDC (minimum 3VDC for low-power requirements) and 0.2W/0.45W low-power coils, it perfectly matches 5A/10A loads (250VAC, 125VAC/30VDC). Furthermore, it can... Stable operation in extreme temperature ranges of 40℃ to +105℃ makes it a cost-effective solution that is "flexible and adaptable + safe and reliable".
