Circuit protection element Rittal 1=4 RX Reitersicherungselement 63 A 3‑pole D02‑E18 (9360802)
Rittal Reiter fuse element 1=4 RX 63 A 3‑pole type D02‑E18 is a thermal/magnetic circuit protection insert designed for use in Rittal switchgear and distribution panels. Intended for three‑phase systems, this device provides overcurrent protection and secure mounting inside modular fuse holders. The compact 3‑pole configuration supports coordinated protection of industrial and commercial electrical circuits where reliable interruption of fault currents is required.
The element combines thermal and magnetic tripping characteristics to cover both overload and short‑circuit conditions. Its standardized D02‑E18 form factor ensures compatibility with Rittal modular fuse systems, allowing straightforward replacement and maintenance. The 63 A rating supports mid‑range current protection needs while the 3‑pole design enables balanced protection across all phases. Robust construction provides stable performance in panel environments.
Install the element into the designated Rittal fuse carrier according to the switchgear manufacturer’s mounting instructions. Ensure the supply is de‑energized before installation. Verify correct seating and mechanical engagement of the element in the holder and confirm the element rating matches the circuit protection requirements. After installation, restore power and perform any required functional checks in line with site procedures.
Select the 63 A element only when it matches the conductor and load characteristics of the protected circuit. Coordinate with upstream and downstream protective devices to maintain selectivity. Replace damaged or aged elements with original compatible inserts and follow periodic inspection intervals specified for electrical distribution equipment.
