SW 600A 600V 3P CLASS J
UL/CSA Fused Disconnect Switch
Sprecher + Schuh’s L11 series of fused and nonfused disconnect switches complies with UL98 service entrance requirements and is NFPA 79 compliant. This family of rod operated switches is suitable for applications that require small panel space and superior short circuit protection.
L11 disconnects are rated up to 1200A and can be operated at up to 600V. They protect motors up to 500HP (@480V). The L11 may be installed on circuits capable of delivering up to 200,000A of short circuit fault current levels typically found in modern industrial facilities.
The new expanded offering of the L11 disconnect series ranges from 100A through 1200A. The L11 Fusible switches are
available from 100A up to 800A, and are designed to be used with Class J & L fuses.
The L11 Non-Fusible switches are available from 100A up to 1200A. Optional auxiliary contacts can also be mounted on the switch for control circuit use. The L11 family performance comes in a compact design, leaving room for additional branch circuit components within the panel.
L11 switches are UL98 approved as a branch circuit protection device and are engineered to provide excellent short-circuit protection for downstream equipment up to 200kA. The L11 fusible switches accept the latest small dimension Class CC, J, L and HRCII fuses. This Type 2 protection limits let-through currents to levels specified for IEC equipment, and ensures that when the short circuit is cleared, the device will be operable.
The L11 offers a modular universal internal handle which provides an interlocked handle for test mode use (30A/60A) and
UL508A and NFPA 79 compliance in North America. The L11 30A & 60A are equipped with removable fuse carriers which
provide dead-front switch protection during fuse change-out. Fuse carriers with neon blown fuse indicators are also available as an option on 30A &60A models. Test mode D7 auxiliary contacts may be installed to provide test capability of control circuit
without energizing the main contacts for the L11-30A/60A swicthes. The L11 switches meet IP20 for finger-safe wiring terminals and IP30 for touch-safe fuse carriers.
All Sprecher + Schuh L11 disconnect switches are UL Listed under File Number E47426, CSA, CE Marked and are designed to meet IEC 947-3, and applicable NEMA requirements.
The Sprecher + Schuh L11 disconnect switches are part of the Rockwell Automation family and share a common design language with their Allen Bradley 194R counterparts. Crossover from AB 194R-J600-1753.
