Special features
Standard with surge counter
High-energy surge handling: The 300 kA per phase rating absorbs severe transients that would otherwise stress drives, PLCs, motors, and contactors. Business impact: Reduced downtime, fewer unexpected faults, and extended asset life translate into lower maintenance costs and more consistent production. Application: Ideal for manufacturing lines, CNC machines, and automated conveyors where rapid transients are common. Delta system compatibility: The 240 delta (4W+G) configuration is designed for delta-connected power architectures widely used in process controls and packaging lines. Business impact: Avoids rewiring or retrofits, enabling fast deployment and maintaining protection coordination. Application: Suitable for industrial facilities with high-leg delta feeders and mixed 3-phase/grounded loads. NEMA 4 enclosure with internal circuit breaker: Rugged enclosure provides weather resistance and ships with an internal breaker, simplifying service and shutdown procedures. Business impact: Reduces field wiring complexity and increases personnel safety. Application: Outdoor switchgear, wash-down areas, and damp production floors. Surge counter and monitoring readiness: Standard surge counter supports proactive maintenance, alerting teams to surge activity and enabling data-driven replacement decisions. Business impact: Improves maintenance planning, reduces emergency service costs, and supports regulatory reporting. Application: Facilities with asset management programs and compliance requirements. Regulatory compliance and longevity: UL 1283, UL 1449, CSA certification, and RoHS compliance help meet safety and environmental standards while enabling simpler procurement. Business impact: Streamlined audits and consistent product stewardship across facilities. Application: Hospitals, data centers, and food & beverage plants with strict standards. Warranty and total cost of ownership: The 15-year warranty, extended to 20 years with registration, lowers replacement risk and supports long-term budgeting for critical power protection. Application: Any mission-critical electrical protection program. Value: Lower TCO, better uptime, and predictable maintenance costs.

FAQs
Install the SPM300240H1R using standard L1-L3 connections plus the neutral/ground (4W+G) configuration. Mount the unit in a suitable location with the NEMA 4 enclosure accessible for servicing and ensure the internal circuit breaker is wired to protect downstream loads. Follow NEC guidelines for clearances, wiring methods, and labeling to enable safe field installation and easy future maintenance.
The 240 delta (4W+G) configuration matches delta-connected power architectures common in process controls and manufacturing lines. With a 300 kA per phase rating, it protects three-phase loads including drives and PLCs from transient surges, while the 4W+G setup simplifies grounding strategies and protection coordination within mixed-load panels.
Yes. The SPM300240H1R is UL 1283 and UL 1449 listed, with CSA certification and RoHS compliance. This combination ensures compliance with electrical safety standards, reduces risk during audits, and supports procurement in facilities with strict regulatory requirements for protective devices.
Yes. The unit features a NEMA 4 enclosure suitable for outdoor and damp environments, providing weather resistance and reliable protection. An internal circuit breaker further enhances safety during servicing, reducing exposure risks for maintenance personnel while keeping critical equipment protected in challenging conditions.
The SPM300240H1R carries a 15-year warranty from delivery, extending to 20 years when registered. This extended coverage lowers total cost of ownership by reducing replacement and downtime costs, delivering long-term protection for mission-critical equipment and predictable budgeting across facilities.
