FAQs
Use the fixed front-terminal design for quick wiring, ensure panel depth allows 82.5 mm clearance, torque connectors to manufacturer specs, and verify 500 V DC operating voltage alongside 1000 V insulation. Confirm compatibility with XT2L-based cabinets and observe terminal accessibility for routine maintenance.
The 25 A nominal rating suits medium-load DC circuits, while the 85 kA short-circuit withstand in series configurations reduces the risk of cascading faults. This enables safer, more reliable protection for motor drives and DC power rails, minimizing downtime during faults.
The device complies with IEC 60947-2 and GB/T 14028.2, and carries CE conformity. RoHS and REACH declarations are available, supporting global procurement and sustainable manufacturing requirements.
Yes. With 500 V DC rated operation, 8 kV impulse withstand, and 85 kA Ics/Icu ratings, it is appropriate for DC distribution in storage and bus systems, provided the application stays within its rated current and surge capabilities.
Its 25,000 mechanical cycles offer durable protection with reduced replacement frequency, while front-terminal wiring speeds installation and servicing. Combined with RoHS/REACH compliance, this translates to lower lifecycle costs and easier compliance in ongoing modernization projects.
