OVERLOAD RELAY CLASS DESIGNATIONS
- Industry standards (NEMA Part ICS 2-222) designate an overload relay by a class number indicating the maximum time in seconds at which it will trip when carrying a current equal to 600 percent of its current rating.
A Class 10 overload relay will trip in 10 seconds or less at a current equal to 600 percent of its rating.
A Class 20 overload relay will trip in 20 seconds or less at a current equal to 600 percent of its rating.
A Class 30 overload relay will trip in 30 seconds or less at a current equal to 600 percent of its rating.
Allen-Bradley standard overload relay protection using either Type N or W heater elements provide Class 20 operation and are recommended for General Application.
Specific Applications may require Class 10 or Class 30 overload relays. Class 10 overload relays are often used with hermetic motors, submersible pumps, or motors with short locked rotor time capability. Class30 overload relays should be used with motors driving high inertia loads where additional accelerating time is needed.
