FAQs
For hazardous locations, install the GUSC3110 30 GB within an appropriate explosionproof enclosure and ensure all wiring methods comply with NEC/CEC requirements. Verify compatibility with Class I Division 1/2 and Class II Division 1/2 conditions, maintain required clearance around the device, and secure the 1" trade size mounting to support a single-pole, 30A circuit. Use proper lugs, seals, and conductors rated for 240 Vac to ensure electrical integrity and safety during operation.
The GUSC3110 30 GB provides NEC/CEC compliance and NEC hazardous ratings including Class I Division 1 and 2, Class II Division 1 and 2, and Class III. It carries NEMA ratings 3, 7, 9, and 12, making it suitable for a wide range of hazardous and outdoor environments. UL certification supports conformance claims, reducing the need for additional third-party validation during audits and equipment procurement.
Yes. The unit is rated at 30A and operates at 240 Vac, with a 1" trade size and a single-pole configuration. This makes it ideal for protecting individual feeders or control circuits in hazardous locations where space is at a premium and reliable protection is required. Proper breaker compatibility and enclosure rating ensure safe integration with existing electrical infrastructure.
The rugged Feraloy iron alloy construction and explosionproof design minimize corrosion and environmental wear, reducing maintenance frequency. Its compact footprint simplifies replacements and retrofits in tight spaces, lowering installation time and field labor costs. Regulatory compliance with NEC/CEC and NEMA ratings aids in faster approvals, decreasing project lag and warranty-related expenses.
