Description

<p>The MMS series offers a robust solution for industrial and commercial applications, where reliability and performance are paramount. Designed to meet stringent standards, this product ensures optimal functionality in demanding environments.</p><p>Operating with a rated voltage of 110 VAC, the illuminated white actuator provides clear visibility even in low-light conditions. The use of metal material enhances durability, making it suitable for harsh settings. With an operational temperature range from -30 to 70 degrees Celsius, this product is versatile across various climates and conditions.</p><p>The degree of protection is IP66, indicating its excellent resistance against dust ingress and powerful water jets. This makes it ideal for outdoor or washdown environments where exposure to elements is a concern.</p><p>Compliance with multiple standards such as CSA C22.2 No. 14, IEC/EN 60073, IEC/EN 60529, IEC/EN 60947-5-1, IEC/EN 60947-5-5, and UL 508 underscores its safety and quality assurance credentials. These approvals confirm that the product meets international benchmarks for electrical equipment used in control circuits.</p><p>Featuring a screw connection type for secure installation and maintenance ease, the MMS series includes a rated insulation voltage of up to 690 V and can withstand impulse voltages up to 4 kV. This ensures resilience against transient overvoltages typically encountered in industrial power systems.</p><p>The contact configuration of 1NO+1NC (one normally open plus one normally closed) allows flexibility in control circuit design while supporting complex operations requiring both make-and-break contacts.</p><p>With an actuator type featuring a short handle designed for momentary function use—meaning it returns to its original position after activation—it provides quick operation feedback essential in emergency stop or reset functions.</p><p>Rated thermal current capacity stands at 10 A which supports substantial electrical loads without overheating risks—crucial for maintaining system integrity during prolonged usage periods.</p><p>Designed with a cutout size of standard industry dimension (22 mm), integration into existing panels or new installations is straightforward without needing special accommodations or modifications.</p><p>Maintained positions marked A, C, B provide additional configuration options tailored to specific application needs ensuring adaptability across various systems setups while light blocks type powered by supply assures consistent illumination performance throughout its lifecycle enhancing user interface interaction efficiency especially critical when immediate visual confirmation is required under operational stress scenarios.</p>
