Single phase induction motors need a device to start under load conditions.
We propose the following range of relays:
Current Type
Traditional MTRP
Gravity type relay used on domestic and light to medium power commercial refrigeration from 1/20hp to about 1/3hp. Also used for applications such as food mixers or coffee grinders.
Product Data Sheet
New MTRP
In thermoplastic compound offers higher wiring flexibility at low cost for large production batches
Product Data Sheet
Adapters to transform the MTRP plug-in relay into a bracket-mount relay:
ADFT - Fixing by means of two vertical self tapping screws
ADTE - Fixing by means of the ear tab on a vertical surface
MTRP determination procedure, according to motor characteristics
Potential Type
RVA
Used on larger commercial applications and air conditioning. Also used for submersible pumps, floor cleaning and other applications requiring high starting torque for motors from 1/2hp to about 3hp

RVA relay versus GE 3ARR3 relay conversion sheets
PTC Type
P Series plug-in type
Used for domestic refrigeration compressors.
Product Data Sheet
P Series bracket mount
With larger PTC elements, for commercial and air conditioning applications.
Product Data Sheet
Energy Saving Type
MTP
It saves energy by combining the advantages of PTC and current-type electro-mechanical starters.
