<p>The SRB Series Expander is a robust and reliable solution designed for industrial and commercial applications requiring precise control and safety. With its solid build, it serves as an essential component in various electrical engineering and automation systems.</p><p>This expander features a rated current of 1000 A, making it suitable for high-demand environments where efficiency and reliability are paramount. The contact configuration includes both Normally Open (NO) and Normally Closed (NC) contacts, providing flexibility for diverse operational needs. The actuator type is an H300 Roller Lever, which ensures smooth operation with a mechanical life of up to one million cycles, ensuring longevity even under frequent use.</p><p>Constructed from durable aluminium housing, the expander is lightweight at just 140 grams while maintaining structural integrity. It boasts a degree of protection rated at IP40, offering adequate protection against solid objects larger than 1 mm but not against liquids. This makes it ideal for controlled indoor environments where dust ingress needs to be minimal.</p><p>The operational temperature is set at 45&#176;C, allowing the device to function optimally within typical industrial settings without overheating concerns. Compliance with EC000030 standards guarantees that this product meets rigorous quality and safety benchmarks.</p><p>One of the standout features of this expander is its slow action mechanism coupled with a positive break NC contact design. This ensures that in the event of an emergency or failure, the contacts will open reliably to prevent accidents or system damage. The actuating speed stands at 0.3 m/s, providing consistent performance across operations.</p><p>With dimensions measuring 43.5 mm in length by 97 mm in height, the sensor size fits seamlessly into existing setups without occupying excessive space. Contact material made from silver enhances conductivity while minimizing resistance-related losses over time.</p><p>The rated insulation voltage is set at 500 V, ensuring safe operation within specified voltage ranges while protecting against potential electrical hazards.</p><p>Overall, the SRB Series Expander combines durability with precision engineering to meet demanding technical requirements efficiently.</p>
