Description

HS810 (MS Series): Product Overview
The ABB HS810 is a specific type code within ABB’s MS series of Manual Motor Starters. This device is a compact, all-in-one solution for the control and protection of small three-phase motors. It functionally replaces the traditional combination of a separate fuse, contactor, and thermal overload relay with a single, integrated unit. The HS810 is operated manually via a rotary handle that provides a visible ON/OFF status and serves as a disconnecting means, satisfying safety requirements for motor isolation.
Its primary role is to protect the motor and the circuit from damage caused by electrical faults. It features a thermal bi-metallic strip for protection against prolonged overloads (e.g., a jammed motor) and an electromagnetic trip mechanism for instantaneous response to short-circuit currents. The overload protection is adjustable to match the Full Load Current (FLC) of the motor, ensuring tailored protection. These starters are designed for simplicity, reliability, and space-saving installation in industrial control panels for machines, pumps, fans, and compressors.

HS810 (MS Series): Technical Specifications
  • ••
    Product Line:​ MS (Manual Starter) Series. A typical full order code would be something like MS132-2.5​ (where the number after ‘MS’ indicates the frame size and the number after the dash indicates the rated current).
  • ••
    Rated Operational Current (Ie):​ Available in various current ratings (e.g., 0.1A to 100A depending on the specific MS frame size).
  • ••
    Rated Insulation Voltage (Ui):​ 690 V / 1000 V
  • ••
    Rated Service Short-Circuit Capacity (Ics):​ Up to 100 kA (depending on the model and backup fuses)
  • ••
    Tripping Class:​ Class 10 (standard for motor protection, meaning it will trip within 10 seconds at 600% of the set current).
  • ••

Core Features & Customer Value
The primary value of the HS810/MS starter is its integration and simplicity. By combining three components into one, it significantly reduces panel space, wiring time, and the number of parts to inventory. For panel builders and machine manufacturers, this translates to lower installation costs, fewer potential points of failure, and a more compact control cabinet design.
The manual operation provides a safe and visible disconnection​ point, which is a crucial safety feature for maintenance. The built-in, adjustable overload protection​ ensures the motor is perfectly protected against overheating, extending its operational life. The high short-circuit breaking capacity, especially when combined with the recommended backup fuses, ensures the system can safely withstand and interrupt severe electrical faults, protecting both personnel and equipment.
Typical Applications
The HS810/MS starter is ubiquitous across industry for controlling and protecting small-to-medium three-phase motors.
  • ••
    Industrial Machinery:​ Driving conveyor belts, pumps, and fans on production lines.
  • ••
    HVAC Systems:​ Controlling fans and compressor motors in heating, ventilation, and air conditioning units.
  • ••
    Water and Wastewater:​ Operating pumps in water treatment and distribution systems.
