COVID-19 UPDATE: Additional safety measures in place

The global outbreak of COVID-19 has created unique and unprecedented operational circumstances for organizations across the world. As of Saturday, April 4th, our services are ✓ fully operational. Our team is currently fully ready and capable of fulfilling orders and otherwise carrying out regular operations.

We remain committed to providing reliable service to our customers while doing everything we can to ensure the safety of our customers, partners, and associates. In accordance with recommendations from the World Health Organization (WHO) and the United States Centers for Disease Control (CDC), we have introduced the following special operational procedures to better ensure the health and safety of our customers, partners, and associates:

  • staff are working remotely, where possible;
  • surfaces throughout our facilities are thoroughly cleaned and sanitized frequently;
  • products are thoroughly cleaned before packaging; and
  • staff working in the office are frequently washing their hands and using sanitizing equipment readily available across our facilities.

We understand that the availability of our products is critical to many organizations and services. As we supply equipment for critical infrastructure services, we do not anticipate a situation where we are unable to continue our regular operation. We will be closely monitoring the situation and keeping our operational status up-to-date here, on our website.

The S811 Soft Starters are solid-state automation control devices. They are manufactured by Eaton Cutler-Hammer. They are compact in size and they can easily fit across-the-line NEMA and IEC starters. They provide a smooth start to 3-phase induction motors. They are mainly used with chillers, pumps, and machine tools that require 85% of the motor’s rated starting torque. The S811 Soft Starters come with a ton of features and they are available in different specifications. The starters feature edge-level sensing control, built-in communication using the Eaton Quick Connect port, advanced diagnostics capabilities (fault queue, control status, and breaker status), and an impressive array of system monitoring and protective features. The edge-sensing feature allows for a motor restart when a fault condition is cleared, the permissive terminal is supplied with 24 Volts DC, and the reset mode parameter is set to “AUTO” or “MANUAL.” 


The S811 Soft Starters are available in different starting modes, including the voltage ramp start and the current limit start. The S811 Soft Starters uses a silicon-controlled rectifier for controlling the starting process. The S811 Soft Starters features the unique soft stopping pump control option which provides a smooth transition for stopping a motor. This stopping mode is also used as a safety feature. The front part of the starters come with easily readable digital interface modules. They allow the operators to feed information into the devices, configure the devices, and troubleshoot them when necessary.  The interfaces are also used to monitor parameters and system values. The S811 Soft Starters feature reduced inrush currents which lead to more stable power grids. The starters are available in different configurations to suit different user requirements. They are available in different frame sizes with different current ratings.
