Why this matters for your operation

The QMR361 isn’t just a switch—it’s a safety and reliability enabler. By combining a robust fused disconnect with a 3-pole configuration, it ensures all three lines are safely interrupted together, reducing the risk of partial energization during servicing. The fusible element adds protective redundancy, mitigating arc energy and providing a clearer path to safe, controlled outages. In everyday terms, this means quicker maintenance, lower risk of equipment damage, and greater peace of mind for your team.

Practical tips for installation and care

• Install in a suitable electrical enclosure or panel that protects against dust, moisture, and mechanical wear.
• Keep spare fuse elements on hand and follow GE-recommended replacement procedures to restore full protection quickly after a fuse change.
• Incorporate the QMR361 into your lockout/tagout workflow to ensure consistent, verifiable isolation during maintenance.
• Schedule periodic inspections to verify connections remain tight and the fusible elements are within their service life limits.

Choose the GE QMR361 for dependable three-pole isolation with built-in fusible protection—designed to perform in demanding environments while supporting safe, efficient maintenance and long-lasting durability.
