Siemens 51SA2CA Selector Switch Short Lever

Product Description

The SIEMENS 51SA2CA is a selector switch with a short lever actuator, designed for use in industrial and commercial control panel applications. Selector switches of this type allow operators to manually switch between two or more circuit positions, making them common in motor control centers, machine panels, and HVAC equipment control circuits. The compact form factor of the 51SA2CA makes it suitable for high-density panel layouts where mounting space is limited. Licensed electricians and panel builders are the primary installers of this type of switching device.

This selector switch is suited for installation in commercial and industrial control enclosures, including motor starters, relay panels, and automated equipment control circuits. The short lever actuator style provides a low-profile alternative to standard knob or long-lever actuators, making it appropriate for applications where operator access space in front of the panel is restricted. It is intended for low-voltage control wiring applications typical in 24-volt to 120-volt class II and class I circuits.

Key Features

• Short lever actuator provides low-profile operator interface for space-constrained panels
• Compact dimensions of 0.776 x 0.311 x 0.311 inches allow high-density panel mounting
• Lightweight construction at 0.573 pounds suitable for standard DIN or panel cutout mounting
• Manual selector function supports multi-position circuit switching in control applications

Compatibility

Designed as an OEM-style replacement or new-installation selector switch for industrial and commercial electrical control panels requiring a short lever actuator configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lockout/tagout the panel before mounting or wiring the switch. Verify the actuator style and circuit position requirements match the panel design before installation. Do not exceed the rated voltage and current specifications for the switch contacts.
