1SFA619212R3021 ABB C3SS3-30R-20 Compact 3-Position Selector Switch 2NO

Why Choose the ABB C3SS3-30R-20 Compact Selector Switch?

The ABB C3SS3-30R-20 is a compact and robust 3-position maintained/momentary selector switch designed for industrial machinery, control panels and automation systems. Identified by ABB order code 1SFA619212R3021, it forms part of the ABB Compact Pushbuttons range and combines the selector operator and contact functions in an efficient all-in-one design.

This selector switch features a red short-handle actuator with a durable chrome metal bezel and three A-B-C operating positions. Its operating mechanism provides fixed A and B positions with spring return from C to B, combining maintained selection with a momentary command in a single operator.

The C3SS3-30R-20 incorporates two normally open (2NO) contacts with no normally closed contacts and is non-illuminated. Designed for standard 22 mm panel mounting, it provides IP66, IP67 and IP69K front protection, a 300 V rated insulation voltage and robust metal-bezel construction for demanding industrial control environments.

Key Advantages

• Compact 3-position maintained/momentary selector switch for industrial control applications.
• Fixed A and B positions with spring return from C to B combine maintained and momentary control functions.

Combined Maintained and Momentary Selector Control

Maintained/momentary selector switches allow different control behaviours to be combined within a single panel-mounted operator. The ABB C3SS3-30R-20 provides fixed A and B positions together with spring return from C to B, enabling the selector to retain a selected position while also providing a temporary spring-return command from the C position.

The ABB Compact range is designed for machine builders, panel builders and industrial automation engineers requiring efficient operator controls with straightforward installation. The C3SS3-30R-20 combines its three-position selector mechanism, integrated 2NO contacts, red short handle and chrome metal bezel in a compact assembly suitable for standard 22 mm control-panel openings.

Typical Applications

• Industrial machinery and equipment.
• Factory automation and production systems.
• Machine mode and temporary command selection.
• Control functions requiring both fixed and spring-return operation.
• Conveyor and material handling systems.
• Process and manufacturing machinery.
• Electrical control panels and operator stations.
• OEM machinery requiring combined maintained and momentary selector control.
