<p>When it comes to robust control solutions, the MMS series offers a versatile and reliable option for industrial and commercial applications. Designed with precision, this product is engineered to meet the demanding requirements of various environments.</p><p>Operating at a rated voltage of 230 VAC, this switch is illuminated in an attractive green hue, providing clear visibility even in dimly lit conditions. The use of metal in its construction ensures durability and resilience against wear and tear. With an operational temperature range from -30 to 70 degrees Celsius, it can perform efficiently across diverse climatic conditions.</p><p>The IP66 degree of protection signifies that this product is dust-tight and protected against powerful water jets, making it suitable for harsh environments where exposure to elements is inevitable. This level of protection aligns with international 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.</p><p>Connection-wise, the switch employs a screw-type mechanism for secure electrical connections. It features a rated insulation voltage of up to 690 V along with a rated impulse withstand voltage of 4 kV—ensuring safety during transient overvoltages.</p><p>The contact configuration includes two normally open (2NO) contacts which are ideal for circuits requiring an uninterrupted flow until manually disengaged. Additionally, the actuator type boasts a long handle design which facilitates ease of operation even when wearing gloves—a common necessity in industrial settings.</p><p>Functionally momentary by nature means that the switch returns to its default position post-operation unless held manually—an attribute crucial for specific control tasks requiring brief engagement periods. Rated thermal current stands at an impressive 10 A catering well to moderate power demands without compromising performance integrity.</p><p>For installation purposes—the cutout size required is standardized at 22 mm ensuring compatibility with existing panel setups or new installations alike while maintained positions A C B provide flexibility depending on application needs. Light blocks are powered via dedicated power supply units enhancing illumination efficiency without additional energy draw from primary circuits.</p><p>Overall this MMS series switch exemplifies reliability adaptability and compliance offering peace-of-mind through stringent adherence to global standards whilst delivering consistent performance across varied industrial landscapes.</p>
