30A, 480 VAC with a 60-400 Hz window supports high-load motors and accessory devices without reconfiguration. Business impact: this reduces changeover errors, accelerates commissioning, and improves power quality in hazardous locations. Application: ideal for SRD interlock systems and stationary equipment where reliable interconnections drive uptime and safety in chemical processing, oil and gas, and mining facilities. Copper-free aluminum housing with brass contacts delivers corrosion resistance and a lighter, easier-to-handle interconnect. This reduces maintenance costs and extends service life in harsh environments. Perfect for hazardous-location interlocks and applications requiring sturdy, code-compliant connections. Cable grip and neoprene bushing provide secure termination and strain relief. This reduces pull-out failures, minimizes vibration-induced wear, and lowers maintenance in rough environments. Ideal for long cable runs and installations subject to movement or temperature cycling. Style 2 grounding ensures a reliable earth path, and its design is optimized for use with SRD spring door receptacles. This simplifies installation, reduces wiring errors, and improves safety during maintenance in hazardous zones. Suitable for explosion-proof interlock assemblies in chemical plants, refineries, and mining operations. NEC/CEC compliance and NEMA ratings 3, 7, 9, 12 ensure regulatory alignment, safer inspections, and interoperability with other safety devices in hazardous locations.
