WEEE Category
5. Small Equipment (No External Dimension More Than 50 cm)
High current rating and a three‑pole fixed configuration with rear terminals deliver robust protection for heavy loads, reducing oversizing and enabling selective coordination in the right panel environments. This improves system availability for critical processes and motor drives in manufacturing and process industries. PR121/P-LSIG release provides precise tripping characteristics, lowering nuisance trips and enabling tailored protection curves for feeders and motors. The device’s electrical durability of up to 8000 cycles and mechanical durability of 15000 cycles translate into longer service life and lower preventive maintenance costs in harsh industrial settings. With a 125 kA short‑circuit rating at typical distribution voltages, upstream equipment is protected from damaging fault energies, supporting safe downtime recovery. RoHS and REACH compliance, CE conformity, and UL 1066 certification simplify procurement and cross‑border installations while the rear‑horizontal terminal arrangement speeds installation and wiring literacy for technicians.

FAQs
This model uses fixed circuit-breaker terminals with rear horizontal entry, which streamlines wiring in panel boards. Ensure appropriate torque on terminal lugs, verify conductor cross‑section, and maintain clearances per UL 1066 guidance to prevent overheating and ensure service access.
Rated at 2500 A with a 600 V nominal voltage, it offers a 125 kA short‑circuit rating at 240/480/600 V and uses the PR121/P‑LSIG release. It is a 3P device designed for AC circuits with fixed terminals, delivering reliable protection for large feeders and motors.
Yes. The 3P fixed configuration, high current rating, and PR121/P‑LSIG release support heavy loads common in MCCs and data centers. The compatibility with SACE Emax components simplifies integration, maintenance planning, and spare parts availability.
The device is CE compliant, UL 1066 listed, and RoHS compliant, with documentation available for reach and environmental declarations. WEEE category classification applies for end‑of‑life handling, easing international procurement and compliance workflows.
Long mechanical and electrical durability (up to 15000 and 8000 cycles respectively) reduces maintenance frequency and replacement risk. Higher reliability translates to lower downtime, improved uptime for critical lines, and favorable total cost of ownership when integrated into a robust SACE Emax ecosystem.
