Description
The Schneider Electric (Barber Colman) M332A00 is a 24V floating, non-spring return terminal block designed to support precise actuator control wiring in commercial HVAC and building automation applications. As a trusted component in the Schneider Electric controls lineup — carrying the legacy of the Barber Colman brand — this terminal block provides a clean, organized wiring interface for floating control signal circuits.
Product Overview
Floating control is a widely used signal type in HVAC systems, allowing actuators to be driven open or closed via discrete directional signals rather than a continuous analog input. The M332A00 terminal block is engineered to support this control methodology in non-spring return actuator configurations, meaning the actuator holds its last commanded position upon loss of power rather than returning to a fail-safe default.
Key Features
- 24V operating voltage — compatible with standard low-voltage HVAC control circuits
- Floating (FLTG) control signal type for directional actuator positioning
- Non-spring return (NON-S/R) configuration — actuator holds last position on power loss
- Terminal block design provides organized, reliable wiring termination
- Schneider Electric (Barber Colman) quality construction for long-term reliability
- Ideal for use in building automation system (BAS) and DDC control panels
Typical Applications
- Damper actuator control wiring in commercial HVAC systems
- VAV box and air handling unit control panels
- Building automation and DDC panel wiring
- Retrofit and replacement of existing Barber Colman terminal block assemblies
Brand Heritage
Schneider Electric acquired the Barber Colman controls product line, continuing the legacy of dependable HVAC controls trusted by mechanical contractors and building automation professionals for decades. The M332A00 maintains that tradition of quality in a compact, field-ready terminal block format.
