ABB SACO64D4 Modular Contactor
Product Overview
The ABB SACO64D4 is a 4-pole (4P) power contactor belonging to ABB’s versatile and widely used SACO (System Accessory) modular contactor series. This device is designed for reliable switching of electrical loads in industrial, commercial, and building automation applications. As a modular component, it is part of a system that allows for easy assembly with various accessories like auxiliary contact blocks, mechanical interlocks, and pneumatic timers.
The SACO64D4 specifically features 4 main power poles (contacts), each rated for the same current, making it suitable for controlling three-phase loads (L1, L2, L3) with an additional pole for a neutral conductor or for switching a complete three-phase system plus an additional circuit. The “D4” suffix typically denotes the coil voltage; in this case, D4 commonly represents a 24V AC/DC standard coil. It is used for remote switching of motors, heaters, transformers, capacitor banks, and other electrical equipment via a control signal.

Main Features and Advantages
-
Modularity & Flexibility: The core strength of the SACO series. The base contactor can be easily combined with snap-on auxiliary contacts, interlocks, and timers to create customized control functions without complex wiring or additional relays.
-
High Performance & Compact Size: Offers a high switching capacity (64A) in a relatively compact DIN-rail mountable footprint, saving panel space.
-
Robust Construction: Designed for long electrical and mechanical life, ensuring reliability in demanding industrial environments.
-
Global Standards Compliance: Complies with major international standards (IEC/EN 60947-4-1), ensuring safety and interoperability.
-
Easy Installation & Wiring: Clear terminal markings, screw-type connections, and straightforward DIN-rail mounting simplify installation.
Application Fields
The SACO64D4 is used wherever a remotely controlled, robust switch for a significant three-phase (or three-phase + neutral) load is required:
-
Motor Control: Starting and stopping of three-phase asynchronous motors (pumps, fans, compressors, conveyors) as part of a direct-on-line (DOL) starter (when paired with an overload relay).
-
Heating Control: Switching of three-phase heating elements in industrial furnaces, ovens, or HVAC systems.
-
Power Distribution: Remote switching of distribution circuits or transformer primaries.
-
Capacitor Bank Switching: For power factor correction units (requires specific contactors rated for capacitive loads, verify suitability).
-
General Industrial Switching: Any application requiring reliable, electrically operated switching of up to 64A loads.
Related Products & Accessories
-
Overload Relay (Essential for motor protection): e.g., ABB TA…DU series thermal overload relay or EF… electronic overload relay, mounted directly below the contactor.
-
Auxiliary Contact Blocks: e.g., SACO A11 (1NO+1NC), SACO A10 (2NO), etc., snapped onto the sides.
-
Mechanical Interlock: e.g., SACO VM – prevents two contactors (e.g., forward/reverse) from closing simultaneously.
-
Pneumatic Timer: e.g., SACO PV – provides on-delay or off-delay functions.
-
Surge Suppressor: For DC coils, to suppress voltage spikes when de-energizing.
-
Control Circuit Fuse/Protection: A small fuse or circuit breaker (e.g., 2-4A) to protect the contactor coil.
