NAL/NALF – for 12kVIndoor switch-disconnector and switch-fuse combination

ABB offers its NAL switch-disconnector for 12kV, up to 1250A, and 1000 operations to support your panel building and CSS manufacturing business needs.

Maximizing your productivity• up to 15 years maintenance intervals (see details

in product manual)• 100 breaking operations at 630 A rated current • Easy replaceable with NAL/NALF-H version design

Optimize your investment• Reduced spare inventories• Recyclable materials• Modular design minimizes installation time

Safeguard your personnel and assets• Wide operating temperatures within -40/+55

Celsius degrees (higher values available based on agreement with manufacturer)

• high making capability up to 67 kA• Visible open insulation gap

NAL 12 kV 400/630 A is a general purpose switch. NAL 12 kV 1250 A is a limited purpose switch

Ensures safety and protection ofpersonnel and assets

Guarantees continuous and reliable operation of critical processes

Reduces maintenance and logistic efforts
