Frequently Asked Questions
What breaking capacity do I need for my industrial disconnect switch?
Breaking capacity requirements depend on your system voltage and available fault current. Our INOSYS LBS series offers 750 VDC per pole for DC applications, while SIRCO models provide ratings up to 1500 VDC. For AC systems, our SIRCO UL 98C switches handle up to 800 VAC with double-breaking per pole design. Our engineers can calculate the proper rating based on your specific electrical system parameters and local utility characteristics.
Are your disconnect switches suitable for outdoor or harsh environment installations?
Yes, our disconnect switches are engineered for harsh environments. The INOSYS series has been tested for vibration, temperature extremes (-40°F to +122°F), salt spray, and humidity. Many models feature IP-rated enclosures and are specifically designed for demanding industrial conditions. We can recommend the appropriate environmental protection level based on your installation location and exposure conditions.
What certifications do your fused disconnect switches carry?
Our products carry comprehensive certifications including UL 98B, UL 98C, IEC 60947-3, CE marking, and CCC standards. Specific models also meet IEEE 519 compliance, NEMA standards, and REACH/RoHS environmental regulations. All certifications are documented with complete technical datasheets and declarations of conformity available for inspection and regulatory compliance verification.
Can I get visible contact indication for safety lockout/tagout procedures?
Absolutely. Our INOSYS and SIRCO disconnect switches feature direct position indication and visible contacts with transparent inspection windows. This allows visual verification of contact separation without removing covers, supporting OSHA lockout/tagout requirements. The sliding bar contact mechanism provides clear indication of switch position, and many models include external position indicators for added safety.
What's the difference between your DC and AC rated disconnect switches?
DC-rated switches like our INOSYS LBS series use specialized arc extinguishing technology designed for DC circuits where arcs are harder to interrupt. They feature patented breaking chambers and are certified to UL 98B for DC applications. AC-rated SIRCO switches are optimized for alternating current with double-breaking per pole design. Using the wrong type can result in inadequate protection—our team ensures you select the correct rating for your application.
How do I properly size fuse holders for motor protection?
Our RMS modular fuse holders accommodate 14x51mm and 22x58mm fuses with ratings up to 100A and 100 kA breaking capacity. Proper sizing requires calculating motor full load current, starting current characteristics, and coordination with upstream protection. Our engineers provide sizing assistance based on NEC Article 430 requirements and motor manufacturer specifications to ensure reliable protection without nuisance tripping.
Do you offer technical support for system integration and installation?
Yes, comprehensive technical support is a core part of our service. Our territory-based engineers provide application assistance, product selection guidance, custom configuration options, and installation support. We offer detailed technical documentation, wiring diagrams, and commissioning checklists. Post-installation, we remain available for troubleshooting, maintenance guidance, and system optimization.
What lead times should I expect for fused disconnect switch orders?
Lead times vary by product configuration and current demand. Standard catalog items typically ship within days, while custom configurations may require 2-4 weeks. For project planning, we recommend contacting our team early in your design phase. We maintain strategic inventory of popular models and can often expedite critical orders. Request pricing includes current availability and shipping information specific to your requirements.
