Feature: Four-pole construction with standard terminals provides complete four-wire protection for three-phase systems, aligning with the behavior of an industrial miniature circuit breaker. Business Impact: Improves fault isolation and simplifies wiring, reducing commissioning time, avoiding miswiring in complex panelboards and MCCs, and supporting safer start-up in automated lines. Application: Ideal for industrial wiring and connectivity in automation panels, motor control centers, and switchgear. Feature: 40 A rating with 15 kAIC breaking capacity offers robust short-circuit protection for feeders and motor loads. Business Impact: Reduces equipment damage risk, minimizes unplanned outages, and supports near-term reliability targets in manufacturing lines. Application: Suitable for control panels and panelboards in automation and machine-building environments. Feature: Very low instantaneous setting tightens protection against fast transients on sensitive loads like PLCs and servo drives. Business Impact: Minimizes nuisance trips while preserving fast response to genuine faults, improving process availability. Application: Critical control circuits and machine interfaces in CNC machines and robotics systems. Feature: Certifications including UL 1077, IEC 60947-2, and CSA C22.2 No.235 ensure regulatory compliance and international acceptance. Business Impact: Facilitates global procurement, simplifies audits, and reduces compliance risk for multinational projects. Application: Global manufacturing facilities and multi-site automation deployments. Feature: Compact 3 x 3 x 3 in footprint, 1 lb weight, and standard terminals enable easy installation and quick field swaps. Business Impact: Lowers labor costs, reduces spare-parts inventory, and accelerates maintenance cycles. Application: Panel cabinets, enclosures, and retrofit projects in existing systems. Feature: Trip Type 2-3X provides selective coordination with upstream protective devices. Business Impact: Enhances reliability by ensuring protective action occurs at the correct location, protecting critical loads without unnecessary downtime.
