Disconnect Switches

L11 30A & 60A Fusible / Non-Fusible

Suitable For Use in Service Entrance Applications

Series L11 30A & 60A Fusible and Non-Fusible Disconnect Switches

Sprecher + Schuh's new L11 series of fused and non-fused 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.

Big performance in a small package

L11 disconnects are rated up to 60A and can be operated at up to 600V. They protect motors up to 30HP (@460V). 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. These rod-operated disconnect switches also incorporate removable fuse carriers with an optional LED blown fuse indicator carrier. This performance comes in a small package, leaving room for additional branch circuit components within the panel.

Maximum protection for downstream equipment

L11 switches are UL98 as a branch circuit protection device and are engineered to provide excellent short-circuit protection for downstream equipment. The L11 fusible switches accept the latest small-dimension Class CC, J 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.

Meets the toughest safety standards

The L11 offers a modular universal internal handle which provides an interlocked handle for test mode use and UL508A and NFPA 79 compliance in North America. The L11 is equipped with removable fuse carriers which provide dead-front switch protection during fuse change-out. Fuse carriers with LED blown fuse indicators are also available as an option. Test mode D7 auxiliary contacts may be installed to provide test capability of control circuit without energizing the main contacts. The L11 switches meet IP20 for finger-safe wiring terminals and IP30 for touch-safe fuse carriers.

L11 Series NFPA 79 Compliant

The L11 series is NFPA79 compliant, which meets the following guidelines under the NFPA 79 standards 5.3.3.1 and 6.2.3.1.2.

The Supply Circuit Disconnecting Device shall:

• Be provided with a permanent means permitting it to be locked in the open position only, independent of the door position.
• Be operable, by qualified persons, independent of the door position without the use of accessory tools or devices.

The interlocking means shall:

• Be reactivated automatically when the door is closed.
• Prevent closing of the disconnecting means while the enclosure door is open, unless an interlock is operated by deliberate action.
