Toshiba Vacuum Contactors

Toshiba's electronic relays provide motor overload and single phase protection, in addition to temperature monitoring and current sensing. When motor protection needs are not quite as elaborate, this relay combines reliable protection against overloads and single phasing with a simple, easily adjustable design.

RC820 Series

Motor Protection Relay Family

Instruction Manual

As a motor overload protection relay, the 2E is adjustable from Class 3 through Class 40 to provide optimum protection and to accommodate reduced voltage starting and high inertia loads. Ground fault and phase reversal modules are available.

Toshiba's 2E relay eliminates many motor failures. This solid state relay features precise motor protection for any horsepower/voltage combination in just three ratings. The 2E provides overload and single phase protection and has an adjustable setting for very wide range from 3 to 40 sec. (starting characteristic, at 600% current) to accomodate reduced voltage start-ups and high inertia loads. The 2E relay complies with international standards as well as UL (USA) listed and CSA (Canada) certified.

  • Overload & Single-Phase Protection - Two protective functions are incorporated.
  • Solid-State - Fully solid-state circuit provides high reliability and precise operation.
  • Manual Test Feature - Manual test switch offers convenience for sequence testing.
  • Manual/Remote/Auto Reset - Wide selection of reset mode gives application flexibility.
  • Surface/Flush Mounting - Selectable surface or flush mounting.
  • Flexibility - The relay allows for a high degree of flexibility for coordinating with wide range of current and trip time settings.
  • Visible Trip Indicator - LED indicator shows relay trip status clearly until reset.
  • Internationally Recognized - The relay complies with international standards as well as UL (USA) listed and CSA (Canada) certified.

Selection of the suitable model may require some preliminary calculations. See "Current Setting" to determine if the calculated "Current Setting %" can be obtained with the selected model given the motor full load current (FLA). Model Selection can also be influenced by wire size which limits the number of turns that can be passed through the CT windows.

SymCom Relays

Any Motor Load that has a small or very non-linear change in current vs. load requires the use of a power monitor for underload, dry run and dead-head protection. The change in power vs. load is more linear for most motor loads and is greater in magnitude than the change in current in all motor loads. This is because power measurements take into account both power factor (pf) and current.

The Contacts Interlock Mechanically with each other in order to ensure a synchronous switching status of both contacts. This guarantees that the alert contact will maintain the same switching status in the event of an error (for example, if the working contact melts from an overload). The controller (or safety controller) detects the alert contact and then compares the set point and actual values. If a difference occurs, measures
