FAQs
Consider mounting location with adequate clearance for the pistol‑handle operation, access for front‑loading fuses, and space for conduit connections. Ensure the panel provides a 22.5 inch depth, 18.45 inch width, and 13.19 inch height envelope to accommodate the device plus wiring. Verify compatibility with three‑pole configurations and reserve space for future maintenance access.
This model is specified for 600 V operation and a 100–200 A class depending on configuration; it features three‑pole operation in a NEMA 12 enclosure and carries CE marking for international compliance. The CF fuse type and pistol‑handle design support safe, front‑access maintenance and protection of downstream equipment.
Yes. The three‑pole configuration is intended for three‑phase circuits, making it a suitable isolator for typical industrial automation panels and motor control centers. It integrates with standard control circuits and aligns with common panel design practices for reliable isolation and maintenance access.
CE marking indicates conformity with applicable EU directives related to electrical safety, EMC, and product compliance. It helps ensure the unit meets performance and safety expectations for international deployments, particularly in European installations and global OEM projects.
Maintenance benefits come from front‑access fuse replacement and a durable enclosure that reduces exposure risk. The pistol handle simplifies operation, while the CF fuse design supports quick replacement, minimizing downtime. Over time, this translates to lower maintenance labor hours and improved equipment availability in automation jobs.
