Application-Specific FAQ
Q: Can the 194R-J400-1753 be used as a motor disconnect for a 25HP, 480VAC motor?
A: Yes. A 25HP / 480VAC motor draws approximately 34A FLA, but with appropriate Class J fuses sized to 175% FLA (~60A), the 30A switch body is used for isolation only — not overcurrent protection. Confirm with your local AHJ and NEC Article 430 for branch circuit sizing.
Q: Is this switch suitable for outdoor installations?
A: The 194R-J400-1753 itself is rated IP20 and must be installed inside a suitable NEMA 3R, 4, or 4X enclosure for outdoor or wet location use.
Q: What fuse size and type does this switch accept?
A: The -1753 suffix designates Class J fuse compatibility. Maximum fuse size is 30A. Use time-delay (dual-element) Class J fuses for motor branch circuit applications per NEC 430.52.
Q: Can I get a Certificate of Conformance (CoC) with my order?
A: Yes. A CoC is available upon request for all orders. Please note this in your order comments or email us at support@konmask.com.
Q: Do you ship to the EU, Middle East, or Southeast Asia?
A: Yes. We ship globally via DHL Express, FedEx International, and UPS Worldwide. Export documentation including commercial invoice and packing list provided for all international shipments.
